SRH77A TWO Temperature Zone plus Humidity Thermo-Hygrometer
The Cooper-Atkins SRH77A is a feature packed meter that consistently beats out the competition. It includes 2 temperature probes and an RH probe. The electronics are built into a rugged case. Temperature range is -40/300F (-40/150C). RH range is 10/95%. Special features include Wet Bulb, F/C, Backlight, Temperature Differential, Scan Mode and Auto Shut-off. This humidity and thermo-hygrometer is a Value Priced Workhorse for your HVAC work. The humidity probe should not be used above 150 degrees F.
Brand New, Factory Fresh - Includes Full Warranty and all Standard Probes
If you need certification, please check the appropriate boxes for your needs.
While the temperature probes can be used to a maximum of 300 degrees, the humidity probe should not be used above 150 degrees F. Temperatures over 150 degrees F will damage the humidity probe. Further, if used in an environment which is smoky or where contaminants present, the humidity probe will likely be damaged. Probes that are used under any of these conditions can not be warranted.
If you have a high temperature/high humidity application, please call our Applications Engineers at 800-390-0004 x1002. The most cost effective way to determine relative humidity at high temperatures is usually to use the Wet Bulb/Dry Bulb method. Call for details.

Relative Humidity Engineering Notes:
Between 20 and 80 percent relative humidity, the accuracy is +/- 2%, and below 20 percent or above 80 percent relative humidity, the accuracy is +/- 3%.
While the temperature probes can be used to a maximum of 300 degrees, the humidity probe should not be used above 150 degrees F. Temperatures over 150 degrees F will likely damage the humidity probe.

They went out of their way to supply me with calibration certificate by email so I could have it for a report.. Really appreciate the extra few steps. Shipping was fast too
Received it faster then expected and in great conditioned. Packaged well.
I purchased the instrument as a Christmas gift so it has not been used yet. It was received with no problems and in new condition. Can send a review at a later date about the use but delivery was fine.
Equipment has "two temperature zones ". But, it only comes with one dry bulb temperature probe.
