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
NIST Traceable Certification provided by Tech Instrumentation

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.

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 to use the Wet Bulb/Dry Bulb method. Call for details.

Easy ordering

Easy ordering, And very prompt service. We ordered the same units in the past and have used him extensively. We are very happy with the high-quality

Great Bread Thermometer

I love the big dial which makes it easy to read, unlike the ones they sell in the stores, which have small dials. I could not find a thermometer made just for yeast and dough. I am glad that I came across your website.

This gift was well received, especially since the recipient picked it out. Got it up and running in time for the good storm (very windy today). We live on the northern coast of California and usually have at least 7 mph winds on a slow day. Today we are having 20-30 mph winds, love the new weather station!!

On time and professional service
