    Hi, jdr,

    Here a review video by one of our customers, the review of the Infrared Thermometer. Maybe you will be interested in it, :)

      I could not understand any word he was saying. I should not have watched the video. I've ordered one :)

      Unfortunately that is in Dutch… Do you know of one in English?

  All the pictures pertain AAA or AA batteries. However the description states 9V battery… which is it?

    Watch the video and you can see that it is not 9V. It's a pair of AAA (or maybe AA).

    Hi, it is AAA batteries. Sorry for the wrong information.
    I correct it~

    Amaze people by predicting when the pot is about to boil.

  Any mechanical engineer should have 10 of these!

  cheapest on ebay is $12.36 AUD so a slight savings, enough for me to impulse buy.

  I bought this exact model a month ago, from a different supplier, for about $15. It does use AAA batteries, and works fine with NiMh batteries.

  I thought I could use this as a fever thermometer, to measure body temperature. You can, but the surface of your body is not the same temperature as the core of your body, and varies depending on many factors (e.g. sweatiness). So as a fever thermometer, it's pretty useless.

  I also thought I could use it to check the temperature of soldering irons. Wrong again, even though this has a 12:1 spot ratio, a soldering iron tip is way too small.

  Also, the temperature shown depends on the "emissivity" of the item. I opened my fridge and tried it on a few things, like plasticware, foil-covered items, plastic bags of food, cardboard boxes containing food, etcetera. All of them were still in the fridge, and all were measured within a minute of opening the door. The thermometer showed temperatures from -2C to +16C, depending what it was pointing at.

  This is best used for things where great precision isn't necessary, maybe like frypans, or applications where you want to discover if something is changing temperature. Or comparing like with like, e.g. finding hotter spots on the ceiling, to discover if your insulation has gaps.

    Hi Russ, thanks for the useful info.
    Have you tried pointing the laser spot at the side, and down into, a saucepan of boiling water? I'd be interested to know exactly what the readings were. I'd also be interested to know what sort of readings you can gain from a distance by pointing it at empty metal pans in an oven at a 'known' temperature. Accurate - or of not much use?
    Cheers.

      Tried it tonight for boiling water. Saucepan was boiling vigorously, element on max heat.

      Lid of saucepan 82-85 degrees (made 5 measurements, temperature not stable).
      Side of saucepan 84-85 degrees.
      From above and just outside the steam plume, firing into the boiling water, 94-95 degrees.

      And I was wrong above, it was Tmart I bought the thermometer from, not another supplier. According to the email Tmart sent, they charged me AU$14.78 on 28 May.

      I particularly wanted this one, as it was the only cheap one I could find that takes AAA batteries. I did find one or two others using AAA batteries, but they were $30 plus. All the rest use a 9V battery.

        Thanks for the tests Russ. They just seem to reinforce the point in your first comment about these things really only being useful for relative measurements.
        Still interested in the oven results if you can be bothered, but I suspect those results will be a bit weird too.

        I also suspect that fooling gullible people into believing that you own a miniature radar speed gun may turn out to be the best possible use for these things…

        I don't have a reliable nor accurate way to know what the temperature of my oven is, so no point in doing that test.

        The unit isn't a bad laser pointer. The laser turns on while the "trigger" is pressed, but it beeps when the measurement is done, so maybe not THAT useful as a laser pointer.
