How to Test the Humidifier Temperature Humidity Sensor

Humidifiers that are used for maintaining optimal curing conditions for cement products usually have temperature humidity sensors in them. These sensors will monitor both the temperature and humidity levels in a room, and adjust them if necessary to aid in the curing process. The steps below outline an easy way to test these sensors.

Tools and Material Needed

• Thermometer
• Humidity Sensor

Step 1 – Find a Controlled Room

Move the humidifier into a room that can be temperature controlled. The smaller the room is, the quicker the results will be determined. Close all doors and windows leading to the room to ensure no outside elements influence the test.

Step 2 – Find the Baseline Levels

Use a handheld thermometer and a humidity sensor (also called a hygrometer or a psychrometer) to find both the temperature and humidity levels of the room.

Step 3 – Set the Humidifier

Set the humidifier so that it will activate itself at the humidity level the room is already at, and shut off at any higher humidity level. The humidifier should immediately turn on and begin jettisoning a heat exchanging water vapor into the air.

Step 4 – Make Sure the Temperature Humidity Sensors Work

Once again using the handheld thermometer and humidity sensor, monitor the levels in the room. When the temperature and humidity levels in the room reach the levels that were set on the humidifier, check to make sure the humidifier shuts itself off. If, according to the handheld thermometer and humidity sensor, the humidifier activates and deactivates itself at the correct levels, then the temperature humidity sensor in the unit is functioning correctly.
