The HABOTEST Infrared Thermometer takes non-contact/contact temperature and humidity measurement. This is an efficient and long lasting all-purpose IR thermometer, which is great for measuring hot objects at a safer distance to monitor electrical, mechanical, HVAC, automotive systems and kitchen appliance. It works on a 9V batttery and Features an color LCD display, adjustable emittance, 12:1 distance-to-spot ratio, K-type thermocouple, mildew alarm, data hold, auto off, switchable degree Celsius/Fahrenheit. Features: ALL-IN-ONE: Able to detect mildew, and measure ambient temperature, ambient humidity, dew point temperature and non-contact temperature. IR THERMOMETER: Reacts very fast within 0.5s, and measures temperatures from -58 to 1472 degree Fahrenheit(-50~800). USER-DEFINED: Emissivity setting(range: 0.10~1.00) and alarm value can be self-defined for different scenarios. HIGH PRECISION: It has a 12:1 Infrared distance-to-spot ratio with laser sighting for pinpointing the measurement area. MIDEW ALARM: Warning light turns red when the object has mildew, and turns yellow when there is a tendency. THERMOCOUPLE TEMPERATURE: Comes with a K-type thermocouple temperature probe, measures temperatures from -58 to 932 degree Fahrenheit(-50~500). UV LEAK DETECTION FLASHLIGHT: Turn on the ultraviolet lamp to pinpoint leaks in air condition and HVAC for flurorecence leak detection. CLEAR TO VIEW: Color LCD display with backlight ensures clear visibility, easy to read. PRACTICAL FUNCTION: Features data hold, low battery indicator, degree Celsius/Fahrenheit switchable. AUTO OFF: Auto power off if there is no operation after 30 seconds. EASY TO CARRY: Comes with a tool bag for protection, compact and lightweight to carry around. APPLICATION: Widely used by mechanics, electricians, HVAC professionals, and even cooks. Note: *Read the user manual carefully before use. *Battery not included. Parameters: Display: Color LCD D:S: 12:1 Emittance: 0.10~1.00 Response Sepectrum: 8~14um Laser:
