The rubberized protective housing s both ergonomic and rugged for daily use. Flip the switch and app immediately knows which side of the system you’re going to place your psychrometer probe. Use the long wireless range, strong magnet, and flexible probe for quick and easy psychrometrics testing.

Maintenance

CLEANING: Clean the exterior with a damp cloth. Do not use detergents or solvents. Do not touch the sensor.
BATTERIES: When the LED slow blinks Red, the batteries must be replaced. Ensure the power is OFF. Remove the single crew from the yellow battery cover. Install 2 x AAA batteries. Monitor battery life in the app’s tool manager.
SENSOR CARE : Cover the sensor with the slipcover when not in use. Extreme conditions or exposure to solvent vapor may offset the RH sensor. To re-calibrate, place the sensor in a controlled environment of 75%RH and between 68°F – 86°F for a  period of 24 hours. To create a 75%RH environment, add wet salt to a clean open container (bottle cap). Be careful to not let the solution touch the probe. Place this container and the probe in a large sealed bag at room temperature, undisturbed for 24 hours.
