BENETECH GM531 Handheld Thermometer Cooking Digital Infrared Thermometer, Measure Range: -50~530 C 1. Degree C Degree F Selection: The unit conversion operation allows data to transfer between Degree C and Degree F units. 2. Multi Function: The infrared temperature gun with AT function , which can measure current ambient temperature. 3. High Accuracy: The laser temperature gauge has a high precision sensor, under self calibration mode, can calibrate the unit between -5.0 Degree C and +5.0 Degree C, adjusting the emissivity from 0.1-1.0 according to the surface material being measured to improve measurement accuracy. 4. Fast Response: The infrared temp gun thermometer with a distance to spot ratio of 12:1 and a response time of less than 500Ms, Spectral response 5~14 um , 0.5s shows the most accurate temperature readings even at great distances,rapidly and accurately measured of object surface temperature. 5. Easy To Use: With backlight, makes it more easier to know the data even at the night . Data hold, low battery indication, auto power-off, small in size ,easy to store and carry. 6. Widely Used (Not for people): Temperature measurement range -50~530 Degree C (-58~986 Degree F). Temperature gun can be used for iron industry temperature test, food surface temperature test, oil surface temperature test, water surface temperature test, electrical Engineering etc.
