Smart Fog® S3 Relative Humidity Sensor

Product Number: S3

Product Name: Smart Fog® S3 Relative Humidity Sensor

Product Description:

The Smart Fog® S3 Relative Humidity Sensor is designed to withstand the elements. A removable sintered filter protects the polymer capacitance sensor from solid objects that may come in contact with the transmitter. The transmitter is available with 4 to 20 mA or 0 to 10 VDC output signals for both temperature and humidity.
