Technical specifications: <br>Measuring range: -50 ~ 680 Colour: Black + Red Material: ABS plastic Accuracy: -58℉~1056℉ Repeatability accuracy: ±0.5% or ±1℃(2℉) Resolution: 0.1℃/0.1℉ Response time: <0.5 S Upper / Lower Temperature Limit Alarm: Red LED Indicator Emissivity: 0.10 ~ 1.00 adjustable (0.01 step) <br>Power supply: 2 x 1.5V AAA batteries (not included) Product dimensionss: approx. 155 x 92 x 42 mm / 6.1 x 3.6 x 1.7 inches. Product weight: approx. 180 g / 6.35 oz. <br> <br> <br>Note: <br>Please note that this product is for industrial use and cannot be used to measure human body temperature.<br>1、【Wide measuring range】: Infrared thermometer With its wide temperature range -50℃~680℃(-58℉~1056℉), you can use this tool for cooking, barbecuing, car maintenance, home repairs or other household tasks <br>2、【Color LCD Display HD Display】: A clearer and larger data display makes this IR lasers thermometer noticeable, especially in the dark, it also has an auto power off function and a low battery indicator to prolong battery life; Auto power off is activated after 10 seconds of inactivity, so it does not run out of battery (battery included). <br>3、【High / Low Temperature Alarm】: The infrared thermometer shows the minimum, maximum, the difference between the two temperatures and the average temperatures; The indication turns red when the measured temperature reaches the high/low temperature you set up, making it easy to detect if a specific temperature is reached or exceeded. <br>4、【 ° C / ° F switchable】: It is possible to switch between Celsius (° C) and Fahrenheit (° F) to easily pass the measurement units. Slightly the measurement button, you can immediately get the M-a -x/Min/Avg. High and low temperature alarm. <br>5、【High Accuracy】: The lasers thermometer can measure quickly in 0.5 seconds. The emissivity of professional infrared thermometer can be adjusted between 0.1?1.0. The measurement error of the lasers thermometer is ± 1.5°C / ± 1.5°C. The distance?point ratio is 12:1, which means you can measure the temperature more accurately than most other infrared thermometers.
