| Ecolog-Net LH2 |
|
ECOLOG-NET LH2 data logger is a network-compatible 4-channel unit that has been designed for applications that require continuous logging and monitoring of temperature and humidity. Can able to connect 2 temperature/RH sensors.
The logger is available with a LAN or wireless LAN interface allowing connectivity through the LAN network to elproLOG software loaded on a PC. Data can be saved on the PC or on the server..
Multiple level alarm features are built in for local or network alarming. The device offers a high level of data safety as it has an internal Lithium battery which ensures that, in the event of a power failure, all the logged data is retained and the internal clock keeps running.
