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.
