The Kestrel 0802 Relative Humidity Calibration Kit is for calibrating all relative humidity measuring Kestrel Meters including the Kestrel 3000. The large container is used to create a stable environment. The small containers are used to hold the saturated salt solution. The saturated salt solutions generate well-defined humidities when they are confined to a contained environment.
Note: YOUR KESTREL SHOULD BE RE-CALIBRATED IF THE RELATIVE HUMIDITY (RH) SENSOR HAS BEEN REPLACED OR HAS SHOWN DRIFT IN ITS RH MEASUREMENT.Learn More
