I noticed Inkbird are having a birthday sale, and this is one of today's deals.
I have one of these and can vouch for how handy it is for doing pizzas in the outdoor oven, but also I have actually used it around the house to check for cold/damp spots around the ceiling.
Good temperature range (-50C to 550C) and response time. Even has a 9V battery included which I wasn't expecting.
Price drop to $23.99 but use the current ebay codes for further savings.
Would be good if there was a 9V eneloop. But I see there at some funky new 9v batteries that you can charge via usb!
A 9V rechargeable battery is quite expensive for just 1 compared to AA and most are only about 200mAh or less
AA eneloop (white) is 1900mAh
Just had a quick look and seems that you can now get 9V rechargables in 650mAh varieties which swings it back in their favour a bit (although price is much higher than eneloop):
9V * 650mAh = 5850mWh
1.2V * 1900mAh = 3300mWh
interesting.. didn't realize but 9v is just made of 6 x LR61
aka AAAA batteries
@m9: https://en.wikipedia.org/wiki/AAAA_battery
LR61 is shorter than AAAA
https://en.wikipedia.org/wiki/Nine-volt_battery
Most PP3-size alkaline batteries are constructed of six individual 1.5 V LR61 cells enclosed in a wrapper.[5] These cells are slightly smaller than LR8D425 AAAA cells and can be used in their place for some devices, even though they are 3.5 mm shorter.
that's alkaline …. carbon 9V are made out of flat discs ….
I have USB 9V lithium battery , work fine and easy to charge.
I've had a similar one for 10+ years, it's still working off the original 9v battery. I use it once every few days.
good to know..
how accurate do you find the gun and what are using measuring with it?
also how far distance can gun measure something without losing accuracy
what 9V brand and how many mAH is it?
if they include a cheapy chinese 9V might not be as good.
Infrared gun would only measure surface temps, so not good for taking temps on food.
Would be better if I could charge it directly via USB
look on Ebay, mine use AAA and looks the same from the outside.
Perfect second home for your smoke alarm backup batteries.
They don't do much in the smoke alarm so they're generally perfectly serviceable when you replace them.
"cold/damp spots around the ceiling"
Is this just indicative of a leak before it gets too bad?
Yeah, indication of a leak.
Good call. Maybe.
Normal Amazon price is $36 put it dips down to $26.99 once in a while. There is also a $3 promotion at Amazon at the moment so you can get it for $23.99 - if for some reason Amazon is better for you.
Got one of these last time, I use it to check the temperature of my milk when making coffees, works well.
what temperature is good coffee ?
Don't think it matters too much as long as it is not cold.
Just don't drink if it is "burning your tongue" temp
You want the milk too be between 60-70 degree depending on how hot you want it
You got plenty of spare time
[This was supposed to be a reply to the above comment about using to measure the temp of steaming milk for coffee]
This test by Decent Espresso looked at this very application. There is quite a lag in reading temp compared with the in-milk thermometer use. Ended up 10 degrees different at the end, even though the test was considered a success at testing the feasibility of this.
If you’re using and espresso machine/milk frother. You can get milk mugs that have a temp gauge built it. I use one when making my cappuccino. Works great.
10c extra for express shipping…get it 1 week instead of 2 weeks.
Bought 1 for I don't know why. ozbargain first ask questions later.
Lucky you, I had to pay a whole $1
Is this good for checking if windows leak air?
Thanks! Smoke one is a good idea.
Great advertising video. I can buy it to be a cat toy! 🐈
Oh yes, 100% awesome cat toy.
Ordered one. thanks OP.
Only getting one coupon code at a time can be used. Anyone else? Total of $21.71 delivered.
With the exception of the first day or two, I can't find myself using it much. I must resist the ozbargain spirit!!!
can we use it to measure Body Temperature e.g fever ?
Probably not accurate enough
The bottom of the eBay page has a note.
PLEASE NOTE:
This is not a medical thermometer. Do not use it to take the temperature of the forehead. Infrared thermometers can't measure the internal temperature of a human, object, or animal; Infrared thermometers are only able to read external surface/skin temperatures. They are not able to read internal body temperature. The measured temperature for humans or animals will not be correct.
probably it is not as sensitive as a medical infrared thermometer.
The medical ones add a couple of degrees to the temp it measures to give your an guesstimate of your internal temp. most of them will have an option to give your the real measured temp which would give a similar result to the inkbird.
One of the images on the page says "Not For human" haha
Yes, but to get an accurate reading you would need to… cough… take a reading in a more 'intimate' fashion.
Ordered, thanks OP :-)
justed ordered outdoor pizza oven this arrived right on time tks op
Dome? If so I just ordered both too haha
Not really sure why I bought but got lots of upvotes so couldn't risk a FOMO moment
"This code can't be applied to your order."
It shows a pic checking steaks on a barbie - how does that work? Don't you need to know the internal temp of the meat - not the surface temp?!
EDIT: I can't think of a use in my daily routine, so might have to pass on a DEAL…. nooooo!
hand in your badge. ozbargainers buy first, think later!
± 2% accuracy seems a bit janky
Is that normal for these things? I don't know much about them…
I have the Bosch PTD 1 model. It's ±1° C. More accurate, but also cost a lot more. These are not bad for the price.
± 2% accuracy seems a bit janky
What are you measuring that needs better accuracy? It's a $20 thermometer for checking if your pizza oven is 250⁰C, 350⁰C or 450⁰C.
2% is more than close enough for most things, problem is that quoted specifications are often widely inaccurate, since the vast majority of devices are not checked (even ANZ Standards "certified" devices are usually not checked either, but there may be some batch or random testing, especially on devices which can cause harm, but this is not one of those devices which would be a priority for testing).
Significant deviance from manufacturer specifications is mostly discovered when there is an accident, injury, or a significant loss of money which leads to compensation.
Handy for getting refunds on cold Ubereats
These are good for working on moving parts in a car (or any moving parts really).
Rubbing one object against another creatures friction, friction creates heat, which can be picked up with a remote temperature sensor.
So, you can diagnose a lot of moving parts in a car, especially the engine (eg you can compare manifold temperatures to see if a component may be failing, such as a spark plug).
You can check for things like worn out rings or inadequate oil or water supply to a part of the engine, etc.
Wish I had one of these when I was mucking around with cars.
P.S. I haven't used this brand or model, so I can't vouch for it's accuracy, or compare to another unit.
Yes i've used mine on the car a few times, last time was when i changed the brake pads and rotors i was able to see the temps were even left to right on rotors, hubs, calipers after a drive which showed they were working evenly and not dragging.
That's a good example.
The accuracy of the device doesn't even really have to be high in this case, just as long as it's consistent.
How accurate is this? I got a cheap one from an online Chinese shop and it is not accurate.
Accurate enough for me. I've compared it to a brand name one and they are within 1 degree from each other
I don't know if you can calibrate this device, but if you can (or if you just want to check it's accuracy) you can use a simple water temperature check.
Put enough ice in a container, and wait for water temperature to drop (it should still have ice in it).
Water temperature (at sea level air pressure) will never drop below 0° Celsius (it will turn to ice instead).
Boiling water (at sea level air pressure) will always stay at 100° Celsius. Any excess heat being immediately removed by formation of bubles (steam) keeping the water temperature at exactly 100° Celsius.
Actually, this was how the Celsius scale was originally defined.
Keep in mind that you want to make sure you are checking the water temperature, not container temperature, nor ice or steam temperature.
Huh, I had no idea you could accurately measure water temp with a $20 IR thermometer!
No, I'm not sure if this is what you meant, but it's the other way around - you can measure the thermometer accuracy with water temperature.
So, for example, if you're measuring temperature of boiling water, and the thermometer is showing anything other than 100° Celsius (at sea level air pressure, which for the most part makes no difference) then the thermometer is not accurate.
Let's sai it reads 103° Celsius, then it's 3° C off (exceeding the +/- 2° C specified).
Then, knowing how much it's off, some digital thermometers let you calibrate (adjust/improve) accuracy by manually setting the thermometer to show 100° C.
Then, you would do the same for water which should be showing 0° C.
If you can't adjust the thermometer, if the difference is big enough to worry you, exchange or return it, or add or subtract the difference for each temperature measurement (around 100° C because you can't assume that error is linear across the temperature range of the thermometer.
But, if it's showing +3° C at both 0° C and 100 ° C, then it's fairly safe to assume that the error is linear in that range, and you can probably extrapolate that error to temperatures below 0° C and above 100° C, and adjust for it (by adding or subtracting the same amount from the reading on the thermometer at other temperatures).
Anyway, this probably sounds more complicated than it really is, but you can just google (or search on YouTube) how to calibrate (or adjust for the error) of a thermometer using water, or other common substances (although water is probably the easiest).
The key is to remember that pure boiling water is always exactly at 100° C (at sea level) and starts to melt from water ice at exactly 0° C (at sea level) and stays at 0° C if there is ice still in the container (but if you're really picky you should probably stir it very gently, once or twice, and wait intil it has settled for a minute or so, before measuring the temperature, to make sure that the water temperature is evenly distributed).
But, honestly, unless the thermometer was showing a big difference at 0° C or 100° C I'd probably just put up with it for general use.
@BooYa: The accuracy will not be changed by any amount of calibration.
It will still be ± 2%, just offset now by whatever you have set via calibration
@trapper: It is calibrating accuracy in a sense, offsetting the reading is what they do at the design and/or testing stage, to increase accuracy after all.
Although, the accuracy of the sensor will not be affected, like you said - it will be offset (increasing the accuracy of the thermometer as a whole).
To give an analogy, it is a similar process to calibrating any electronic device, like HDR on TV, or other picture settings (the accuracy of the display is improved while the accuracy of the panel remains the same).
But I know what you mean, and it's a perfectly valid point of view, the difference between our statements is more semantic than anything, since the end result is the same.
@OzBragain: Yes. Exactly.
I would just note that some
people often confuse accuracy and precision, or think they are the same thing, they are not.
And yes, you can check the accuracy (not precision) of practically any thermometer using this method (just like you can separate liquids which are in a mixture, by knowing at what temperature they evaporate, and separate them in a process called fractional distillation).
Although, I don't know how useful that last example is to explain my point (it may help to point out that many people use fractional distillation in their home brewing kit, to separate ethyl alcohol from the other liquids and solids in the mixture).
But, the general gist of it is that every element and compound (chemicals) have their own physical and chemical properties (like melting points) which can be used to do some useful things, knowing what those temperatures are.
@OzBragain: Lol, I know it's long and convoluted. I wrote it (after not sleeping for second night in a row) 🤣
This will be good to check if the chock is done.
Mmm. Not really. You should get a probe thermo to check internal temp
Only if the chook does a brown eye with immaculate orientation.
Oss
I'm going to ask the rep to restock… TBA
Rep says out of stock. No more.
Sorry ppl.
Tell the rep to restock or people will spend their money elsewhere :)
have my own one for cooking, checking the pan temp before i start putting things onto it, works great.
$23.99 on Amazon with a code to Rick to apply, matching the non coded eBay price, for anyone still keen at this price which is still decent as per camel x3
