Radio data logger with external temperature sensor for remote temperature

The tempmate.®-R radio data logger LGR36 features an external temperature sensor (accuracy ± 0.3°C) for remote temperature monitoring. The measurements are transmitted directly to a PC, where they are then displayed. The measurement data is transmitted live by radio to the monitoring workstation, or is stored in the data logger until it is called up wirelessly.

Product recommendations:

  • LGR36: Data logger without probe.
  • STE51: tempmate.®-R external temperature sensor, directly connectable to the LGR36.
Radio range 30m to 1km (depending on the antenna on the PC)
Interface to the sensor With external plug connection or tempmate.®-R PT1000 probe, ordered separately (see available probes).
Storage capacity 32,256 timestamped measurements
Radio frequency ISM 868 MHz
