Reed R8706-kit Psychrometer with Humidity Calibration Standards

This kit pairs the REED 8706 digital psychrometer/thermo-hygrometer with a set of 33% and 75% humidity calibration standards, so users can verify and maintain the meter's accuracy in the field. The 8706 itself simultaneously reads relative humidity, air temperature, dew point, and wet bulb temperature, with an optional probe available for contact/differential temperature checks.
