Calibration Kit for RH Sensors

These reusable jars are made to easily calibrate relative humidity in the pSense High Accuracy Portable CO2 Meter and our pSense CO2 + CO + RH/T Portable Meter & Data Logger.

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.
