Mini Diver

Mini Diver

Overview

Hydrolab Quanta Meter

The Diver Water Level Logger is the smallest groundwater datalogger in the world!

It measures groundwater levels and groundwater temperatures simply and reliably and it fits in the palm of your hand. The Diver has a fully sealed stainless steel housing that provides protection from moisture or external electrical influences (FaradayCage). The housing contains the pressure sensor, the temperature sensor, the datalogger and the battery that can last up ten years.

The fully automatic, easily programmed Diver allows measurements at selected time intervals as small as 0.5 seconds with no wraparound programming – so data will cannot be accidentally overridden. Logarithmic and event-based sampling regimes are also easily programmed into the Diver software (included). Once programmed and installed, the Diver remains out of sight suspended on either a stainless steel cable or direct read cable.

With a length of only 90mm and a diameter of 22mm, the Diver can be used in almost any groundwater monitoring well. The memory is capable of storing 24,000 recordings, enabling you to execute and to store a measurement every 10 minutes for six months before the memory is full. The Diver can be used with the BaroDiver for improved accuracy through Barometric compensation of data.
