✅【BETTER ACCURACY AND QUICKER】-Non-contact laser measurement & K probe contact measurement with13 Points Laser Guidance and adjustable emissivity (0.1-1.0) for more accurate measurement.French HTU20 temperature sensor and laser head are used to display the ambient temperature/humidity, dew point,spoilage temperature, surface and interior temperature of the object at the same time..
✅【HIGH TEMP GUN THERMOMETER】HD colorful VA display and backlight display for work in low-light or no-light conditions,Unit switch (℃/℉),MAX/HOLD data,Low battery indication so you never accidentally run out of juice and auto-off function in 25 seconds to extend battery life (Batteries included),Response Time:003c0.5s.
✅【2 ALARM MODES】This Temp Gun has Spoilage Alarm Mode and Temperature Difference Alarm Mode. The Spoilage alarm mode is suitable for measuring wood, walls, food and other moldy objects. The temperature difference alarm mode can help you judge whether the difference temperature between the surface of the object and the ambient is greater than 5℃, which is very helpful to determine whether the surface temperature of the object is normal in a constant temperature environment..

Handheld digital meter measures ambient level of carbon dioxide (CO2) to monitor indoor air quality and performance of heating, ventilation, and air-conditioning systems.
Displays current CO2 levels, long-term average CO2 levels measured over an 8-hour period, and short-term average CO2 levels measured over a 15-minute period.
Alarm notifies operator when CO2 levels reach or exceed a preset threshold, CO2 measurement up to 9999 ppm.
Liquid crystal display (LCD) shows ambient CO2 levels, as well as air, wet bulb, or dew point temperature and humidity.
Manual calibration helps ensure accurate humidity and CO2 readings.

Measures CO, CO2, Temperature, Humidity, Wet Bulb and Dew Point on large backlit LCD display.
STEL (Short Term Exposure Limit – 15 minute weighted average).
NDIR (non-dispersive infrared) waveguide technology.
