Tax included

Delivery time from stock or 7 days.

THERMASGARD® RSTF resistance thermometre with passive output, in an elegant plastic housing with snap-on cover, base with 4-hole attachment, for mounting on vertically or horizontally installed in-wall flush boxes, with predetermined breaking point for on-wall cable entry. The device is specifically used for temperature detection in larger rooms.

The RSTF room radiation temperature measuring transducer determines the effective portion of active radiation or the effective radiant heat at the measured location. Excellent measuring results, representative of the specific room, are achieved thanks to the measuring method employed by the dark radiation sensor.
