e+WATER L

e+WATER L Surface Water Level Loggers are for the measurement and logging of water level/depth and temperature and the depth of rivers, canals, lakes. The loggers are able to cope with a water fluctuation from 0m to 200cm and are capable of storing up to 28,000 measurements. These vented surface water level loggers have built in barometric compensation so are more accurate than standard down well unvented water level loggers. They are also frost resistant if exposed to the elements.

They form part of our telemetry systems for remote programming and data interrogation.

Diver-Office

Downloadable Diver-Office software for a desktop solution for the Diver range of water level loggers.

Diver-Office Premium is upgraded software for managing, reporting and manipulating Diver groundwater data.
