The thermometer is a non-contact infrared thermometer which displays the present reading and the maximum reading simultaneously. It can be used to measure surface temperatures of hot, hazardous, or hard-to-reach objects. It features safety, fast operation, and high accuracy.   Specifications Measurement Range    -38℃ to +520℃ (-36.4℉ to +968℉) Operating Temperature    0℃ to 40℃ (32℉ to 104℉) Accuracy (Tamb = 23 ± 3℃)    ± 2℃ (4℉) or 2% of reading, whichever is greater Spectral Response    7.5 - 13.5 μm Emissivity    0.95 Resolution    0.1℃/0.1℉ Response Time    1s, 95% response Distance : Spot    8 : 1 Battery    1.5V battery, AAA or equivalent, 2 pieces Dimensions    160 x 118 x 40mm Weight    about 158g (including battery) The thermometer will automatically shut off if it is left idle for more than 15sec.   LCD ERROR MESSAGES The thermometer incorporates visual diagnostic messages as follows: " Err " is displayed when the ambient temperature is lower than 0℃ (32℉) or higher than +40℃ (104℉). " Hi " or " Lo " is displayed when the temperature being measured is outside the measurement range.   EMC/RFI Readings may be affected if the thermometer is operated in an intense electromagnetic field, but the performance of the thermometer will not be permanently affected.
