Kestrel RH Calibration Kit for Kestrel 3000, 3500, 4000 Series Meters

Your Kestrel should be re-calibrated if the Relative Humidity (RH) sensor has been replaced or has shown drift in its RH measurement.

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 humidity when they are confined to a contained environment.

The RH calibration kit includes the following items:

• Three clear, sealable containers
• One container with magnesium chloride solution
• One container with sodium chloride solution
• Two wooden scrapers
• An insulated carrying case to hold all of the above and maintain a stable environment while performing calibration
• Not intended for Kestrel 5 Series Meters
