    Thanks for the very informative video! If measuring a surface over a fire, how accurate are they? I'm thinking of pottery in a kiln, iron in a forge, food in a campfire, etc. If you can avoid the smoke, are they accurate, completely worthless, or somewhere in between?

      Dear Tim! IR thermometers are good tools for measuring temperature from a safe distance. However, for measuring the temperature inside the kiln we suggest a pyrometer. We have selected for you a few temperature meters that are in the range, check it here: www.tme.eu/en/katalog/temperature-meters_112631/?s_field=1000011&s_order=desc&id_category=112631&search=thermometer&visible_params=2%2C1785%2C1786%2C1784%2C72%2C55%2C1747%2C2950%2C1952%2C317%2C1605%2C74%2C1807%2C82%2C1970%2C1813%2C375%2C384%2C1854%2C383%2C2390%2C2998%2C1810%2C1808%2C1594%2C3177%2C3035%2C32%2C1971%2C436%2C536%2C1967%2C885%2C351%2C1953%2C1825%2C707&mapped_params=1952%3A1821635%2C1819696%2C1821567%2C1819815%2C1819791%2C1821004%3B

    • @TME.ElectronicComponents
      @TME.ElectronicComponents  2 ปีที่แล้ว +1

      Hey :)
      Yes, you can give it some time and let the temperature stabilize.
      Overall, low emissivity objects such as shiny metals, emit less infrared energy and this can be a challenge for the IR thermometer. To get a more accurate measurement you can apply black tape or flat paint to the shiny surface, wait a bit and then measure.
      We hope it answers your question,
      Have a great day!

      Yes. The temperature of an industrial IR thermometer can range from -50 up to 1000 centigrade and even more. Therefore the accuracy is +/-1 deg which is enough for industrial applications. On the other hand, medical IR thermometers have much lower range between 32 up to 43 centigrade and ten times the accuracy of an industrial IR thermometer.

      Hey Jim, that's a great question!
      The emissivity for cast iron is between 0.7 to 0.9.
      For better accuracy, you can measure with an IR thermometer and a probe. Then, set the emissivity that will give you the same temperature. We hope it answers your question.

      @fractalnomics 3 ปีที่แล้ว

      @@onisti2635 No, it will not measure the air temperature at any temperature. It does measure some gases in the air, CO2 CH4 H2O vapour, but, they are trace gases. It does not nitrogen or oxygen, 99% of the dry atmosphere. And if you think these gases have something in common with what are termed the greenhouse gases and non-green house gases, they are in common. John Tyndall used the thermopile, the same as used in your device, to determine what he thought to be, and we still think are the greenhouse gases. He was wrong, we are wrong. They are the thermal electric and non-thermal electric gases, that's all. Oxygen and Nitrogen have emission spectra lines in the infrared and these are inferred by the Raman spectrometer. This is my discovery, no scientist enjoys what I have uncovered, I wonder why? Any ideas?

      @@onisti2635 Hi, we have to distinguish thermocouples from thermopiles, thermopiles are many thermo couples in series. Thermocouples are used in screeens and under touge, they are good and accurate. Not so from thermopiles, as used in the IR 'gun'. They will measure the screens, but not the 'air' directly in front of the thermopile detector, that's my point. Btw, they, thermopiles, don't measure (very well) the solid metal (metalloid) germanium either. By these substances all have a temperature though.

      Dear Fire Goddess, that's a wonderful question. But before we answer, we want to emphasize that those IR thermometers are not for medical purposes but for measuring the temperature of surfaces in a workshop, warehouse, HVAC, etc.
      The accuracy of the measurement can be found in the specification tab under the "Non-contact temperature measuring accuracy". With this information, you can calculate the divination from the real temperature.
      For example, the FLUKE 561 IR thermometer has an accuracy of +/-1% or +/-1deg (whichever is greater).
      This means that for a normal body temperature, 36.5deg, the measured value can range between 36.2-36.8 (for +/-1%) or 35.5-37.5 (for +/-1deg). In this case, the higher deviation is +/-1deg and hence a normal body temperature can be identified as fever (37.5deg) :/
      We hope this answers your question and we wish you a wonderful day :-D

      Because you’re wrist is generally a lower temperature, even if you have a fever. So if you have a fever but get scanned on your wrist, it may not show. Forehead is generally more reliable. And just so you know, they don’t hurt you. All they do is absorb the heat of whatever is around it, which is why they’re not ideal especially in hot and cold weather.
