Indigo 201 transmitter with exchangeable Humidity and Temperature probe, Display, Current loop, relays , 0.8%RH/0.1°C accuracy

The Indigo 201 is an IP65-rated analog output transmitter, a host device for Indigo compatible probes with display, 4 ... 20 current loop output and two relays. Probes can be connected directly or with a remote cable (available as accessories) to the Indigo 201. User configuration and temporary viewing of data is easy and convenient with a wireless browser-based user interface.

The optional humidity and temperature probes (HMP4, HMP5, HMP7 and HMP8) and the temperature probe TMP1 are intelligent probes with 2m cable lenght. They are ideal for measuring humidity in demanding industrial applications. All humidity probes come with a traceable 5- point humidity calibration certificate. The probes are equipped with the latest HUMICAPR2 composite sensor. Sensor purge functionality improves measurement performance under applications where the probe is exposed to high chemical concentrations.
