872-3 Digital Psychrometer is designed to take very accurate quick readings for all areas where accurate relative humidity, temperature, dew point, and wet bulb temperatures must be taken. Equipped with an big LCD screen that can display temperature and humidity simultaneously. It uses rotronic capacitor humidity sensor for the accurate reading and condensation will not affect meters' accuracy. This thermo-hygrometer has a reliable built-in microprocessor circuitry and Dew Point & Wet bulb is calculated in seconds. It also has advance functional features such as easy to self-calibrate by salt bottle, replaceable remote probe, maximum/minimum and reset function, hold function, backlight function, switchable °C & F, tripod mountable, auto power off that can be disable anytime, low battery indicator and battery life that can last 50 to 100 hours.

BUILT FOR RELIABILITY - It quickly and accurately measure and easily reach the inside of the pipe tubing, even in air ducts, corners and small or cramped spaces. The practice of manually swinging a wet bulb hygrometer for several minutes to measure dew point has been completely done away with using the digital psychrometer.

A must device for HVAC engineers' use. No more whirling and referring to a chart! This professional meter, with proper care, will provide years of safe reliable service.
