Infrared Thermometer comes with a single laser pointer to indicate the target under test. It has a temperature range from -50 C to 1000 C (-58 F to 1832 F) with an accuracy of +/- 1.5%. This 1000 Degrees C Digital Non-Contact Infrared Thermometer features 31/2 digits (1999 Counts) backlit LCD display that gives a clear view of the readings. It has a fixed emissivity of 0.95. The distance to sighting (D.S.) ratio is 50:1 and the spectral response is 8 to 14um. The auto data hold function freezes the displayed data for users to get an accurate reading. The auto power-off turns off the thermometer, when not in use and improves battery life. Its compact design enhances user comfort and ease of use.

The underlying technology for Infrared Radiation Pyrometers is based on the principle that all objects emit radiation at wavelengths in the infrared region of the electromagnetic radiation spectrum. Infrared is that portion of the electromagnetic spectrum that lies beyond the visible (blue to red, 0.4-0.75 um) response of the human eye. Infrared thermometers measure this radiation and provide an output signal calibrated in a variety of ranges.
