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.
