Measure, log and report...

Precision thermo-hygrometer with drift-free measurement even for constantly high relative humidity values. This measuring device is especially suited for monitoring climate chambers, rooms with tropical climate conditions and for use in food production.
The sensor is insensitive to dewing, since the sensor electronics is potted to protect against climatic effects. This makes the sensor with protective housing for protection against solar radiation and precipitation ideal for outdoor use.

Sensor:

• Temperature sensor:
  • Measuring range: -20°C...80°C
• Relative humidity sensor:
  • Measuring range: 0...100% RH
