The Kestrel RH Weather Meter Calibration Kit allows you to perform dozens of recalibrations of your Kestrel meter in the field to improve sensor accuracy and mitigate the effects of RH drift. If using distilled water, it can even be used an indefinite number of times. This kit includes the following items:
- Three clear, sealable containers
- One container with magnesium chloride salt
- One container with sodium chloride salt
- An insulated carrying case to hold all of the above and maintain a stable environment while performing calibration
Recalibrating a Kestrel meter using this kit takes approximately 50 hours including setup and calibration. This calibration kit is simple and easy to use, with full instructions in the user manual. RH Field calibration of Kestrel 3000-3500 Series, 4 Series, and 5 Series units usually return units to within +/-3% accuracy, but actual results will vary depending on your control of the calibration environment. It’s crucial to perform the calibration in a climate-controlled environment such as a home or office to ensure the best results.
