Constant air flow reduces chance of oversaturating. This chamber is available as a complete unit or an upgrade kit for your current humidity sensor. It will run off the 24 VAC for the fan and 12 VDC power from the controller for the humidity sensor or with an optional transformer. The fan air flow rate is over 25 CFM [.7 CMM], so the unit can be placed out of the way and still get accurate readings. With the Val-Co Humidity Sensor, you can get a 15 second response time.
