Lufft OPUS20 THI
Temperature and rel. Humidity
For climate monitoring in buildings
and the control of all climate-sensitive
production processes, in electronic
data-processing centres, control
cabinets, wind turbines, storage rooms
and museums.
The OPUS20 runs on batteries or
powered via USB. Alternatively, you
have the possibility to power the device
via POE (Power over Ethernet).
The only LAN datalogger with built-in
sensors and the highest precision
For high-precision
