Capacitive Humidity and Temperature Probes

RHT10E & RHT20E

The RHT10E & RHT20E are cost effective, compact and robust RH and temperature probes for use with Eltek GenII transmitters (the probes are not suitable for other applications).
The sensor is housed in a replaceable protective cap with a non-removable stainless steel (grade 316) 100 micron dust filter.
The RHT10E & RHT20E are intended for indoor, non-condensing applications. The RH and temp sensor is removable thereby permitting exchange or calibration.
The lead is non detachable and can be ordered at a user-specified length from 1m up to 10m.
