IZAR RADIO EXTERN TEMPERATURE
IZAR RE TEMP radio generation operates under RealData protocol (Wireless M-Bus) at a frequency of 868 MHz. This radio is equipped with a temperature sensor with a wide measuring range (-55°C to +125°C). IZAR RE TEMP radio comes fully programmed and ready to use with an identification number.
IZAR RE TEMP radio transmits the ambient as well as the minimal, maximal and average temperature over the last 6-hours period. IZAR RE TEMP can be read in mobile mode with a handheld computer together with an IZAR RECEIVER BT. In fixed network mode, reading is performed using either the IZAR RDC STANDARD/BATTERY or PREMIUM or the M-Bus IZAR CENTER installation.

Principle of operation
IZAR RE 868 TEMP includes a temperature sensor that records current, lowest, highest and average temperature on a 6-hours period.
This radio can be read through walk-by/drive-by or fixed network and is 100 % compatible with RealData (Wireless MBus) protocol. IZAR RE 868 TEMP enables the control of leak on the overheated water network and the detection of breaks in the cold chain.
