The Micro-Diver is a submersible data logger for long-term, uninterrupted, real-time water level monitoring using a pressure sensor when submerged at a fixed level under the water surface. The pressure sensor measures the equivalent hydrostatic pressure of the water above the sensor diaphragm to calculate the total water depth. The Diver autonomously measures pressure and temperature and records them in its internal memory. The Diver is ideal for ground and surface water level applications.
The Micro-Diver is specifically designed for monitoring wells or drive-points too small to accommodate larger data loggers. In addition to its compact size, the Micro-Diver’s memory capacity can store up to 48,000 measurements (date/time, pressure and temperature) – almost one measurement every ten minutes for an entire year.
The Micro-Diver has the following sample methods: fixed-length intervals, event dependent, averaging and pumping test.
The Micro-Diver is available in the following pressure ranges: 10 m, 20 m, 50 m and 100 m..

Monitoring groundwater under potentially corrosive conditions, such as brackish water and seawater, requires a robust and durable datalogger.
The ceramic-shelled Cera-Diver is designed specifically for such environments. This highly reliable and compact Diver measures groundwater levels with a typical accuracy of ±0.05% full scale.
In addition to its rugged casing, the Cera-Diver’s memory capacity can store up to 48,000 measurements (date/time, pressure and temperature) – almost one measurement every ten minutes for an entire year.
The Cera-Diver has the following sample methods: fixed-length intervals, event dependent, averaging and pumping test.
The Cera-Diver is available in the following pressure ranges: 10 m, 20 m, 50 m and 100 m.
