Technical Specification

Sensor	1 or 2 RTD sensors (PT100) connectable
Maximum measurement range	±0.2 °C (-200 °C bis 850 °C) without Pt100
Reproducibility measurement channel	+/- 0.1°C (measurement range -100 °C to +200 °C of the channel) with the logger at 23 °C ambient temperature NOTE: The reproducibility of the PT100 sensor is to be added still.
Reproducibility measurement channel for maximum range	+/- 0.2 °C (measurement range -200 °C to +850 °C of the channel) with the logger at 23 °C ambient temperature NOTE: The reproducibility of the PT100 sensor is to be added still.
Frequency	868 / 915 MHz
RF Range logger to gateway	868 MHz: 20 - 50 m (within a building) 915 MHz: 15 - 25 m (within a building)
Maximum number of logger per gateway (per channel)	60 loggers
