Calibration Kit for RH Sensors

These reusable jars are made to easily calibrate relative humidity in the pSense Portable CO2 Meter, the pSense High Accuracy Portable CO2 Meter, and the cSense CO2-Temp-%RH Meter with relay. 

To use simply unstopper the jar, insert the probe into the jar, and start the calibration mode. It's that easy!

Note: Each meter has specific instructions on how to calibrate relative humidity. Make sure to follow the instructions closely to avoid damaging the meter.
