Review on UNI-T UT301A+ Infrared Thermometer: Non-Contact Laser Temperature Gun, LCD Display, -25.6°F to 788°F (-32°C to 420°C), Red & Grey by David Butterfield

This infrared thermometer feels good in your hand, is easy to target with a very bright laser dot, and has a clear and colorful display. to operate the device correctly. Understanding the emissivity concept is important to get accurate results. Not all surfaces radiate energy equally, in the form of radiant heat, and this device must be told the emissivity of the material in order to calculate temperature correctly. The instructions provide an emissivity table for common materials, and you use the value in the table to set the thermometer's emissivity configuration option accordingly. You will find that the standard value works well for many types of ordinary surfaces, but metal surfaces often have a very different emissivity from the standard value, so refer again to the attached table, especially if you think the temperature reading is off too far . Photographs showing a comparison of the temperature of the air surrounding a dark carton with a calibrated instrument and the temperature of the carton measured with an infrared thermometer. As you can see the readings are close together and the error is within the published accuracy of the device. If this was a helpful review, could you click the helpful button below? Thanks very much!
