Relative Humidity Sensor

The RH-5 is a low-cost continuous measurement relative humidity sensor. It is compatible with 9300 loggers equipped with rechargeable batteries and PV panels as well as Symphonie loggers equipped with any iPack and RH SCM.

The RH-5 uses a polymer resistor sensor which provides excellent linearity and sensitivity with fast response and long-term stability. Mounts to underside of shelter box. Includes 1.5 m (5 feet) cable.
