  • Description

  • General

Measurement and transmission of temperature
and relative humidity

With the tempmate.®-R data loggers, temperature and relative humidity can be measured and remotely monitored wirelessly. 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 stored in the data logger until it is called up wirelessly (by radio).

This product is available in three variants, depending on the desired measurement accuracy:

  • LOG20: with accuracy +/- 0.5°C (temp) and +/- 4.5% relative humidity
  • LOG22: with accuracy +/- 0.4°C (temp) and +/- 3% relative humidity
  • LOG25: Sensor with accuracy +/- 0.3°C and +/- 2% relative humidity
Sensor Internal; external upon request
Resolution measurement frequency 1s
Memory 100 years (flash memory);
32,768 timestamped measurements
Radio range 30m to 1km (depending on the antenna on the PC)
Measurement frequency Between 1x per minute and
1x every 4 hours
