HD35ED – Wireless Data Logger System
Brand: Delta OHM S.R.L.HD35ED series of data loggers: the data loggers are the remote devices connected to the measuring probes.
They are installed in the environments to be monitored and are powered by the internal battery (not rechargeable) that allows a long working life.
The acquired measurements are stored in the internal memory and sent to the base unit automatically at regular intervals or upon user request. Versions with or without LCD are available.
The versions with LCD allow the measurements and the RF signal quality to be viewed also at the installation site and allow the data logger configuration through the front keyboard too.
