The ULTIMETER Outdoor Humidity/Temperature Sensor utilizes a precision thick-film polymer capacitance device to measure humidity. The sensor is used in a low-frequency oscillator circuit, which changes frequency as the relative humidity of the air changes. The output of the oscillator is fed into the microprocessor. The ULTIMETER Temperature Sensor is a precision aged interchangeable thermistor. Designed for under-eaves mounting, out of direct sun exposure.
- The exceptional long-term stability of the humidity sensor element means years of use without recalibration.
- Operates over the full humidity range, from 0% to 100% R.H.
- Temperature range is -55 F to 150 F.
- Includes 40 ft. cable and mounting hardware (longer cable lengths optional).
