RIEF DESCRIPTION
IZAR RE 868 TEMP is a unidirectional radio transmitter intended for temperature readings
with a wide measuring range (-55 °C to +125 °C). Equipped with an external temperature
sensor, IZAR RE 868 TEMP uses the M
-
Bus Wireless international communication
standard and can therefore be read by any system using this protocol.
IZAR RE 868 TEMP is intended for radio reading in mobile mode or fixed network. The
lifetime of the module
can reach
up to 12 years (non-replaceable battery).
Reading IZAR RE 868 TEMP is done, in mobile mode, with an IZAR PSION handheld
