Level Data Logger PD-3/4/5

DATA LOGGER WITH PROBES FOR GROUNDWATER MONITORING

Level Data Loggers are the ideal measurement devices for reliable measuring of water level and temperature, conductivity or pH-value or further parameters in groundwater, at springs, or lakes. Appropriately to the measuring requirements diverse loggers and probes can be supplied.

Description
