1Wide 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 2Color 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). 3High / 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. 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. 5High Accuracy: The lasers thermometer can measure quickly in 0.5 seconds. The emissivity of professional infrared thermometer can be adjusted between 0.11.0. The measurement error of the lasers thermometer is 1.5C / 1.5C. The distancepoint ratio is 12:1, which means you can measure the temperature more accurately than most other infrared thermometers.Technical specifications: 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: 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.
