TEMPERATURE AND HUMIDITY SENSOR
► Product Description
- RHP SERIES are temperature and humidity sensors, the output signal can be Vol or current and can be used by customers removable temperature sensors (passive temperature or RTD). Capacitive polymer capacitance humidity sensor with accuracy of 2%, 3% or 5% depending on requirements. The duct-mounted type can add a 2-line LCD display.
