Micro Diver

Micro Diver


Hydrolab Quanta Meter

Measuring only 88 mm in length and 18 mm in diameter, the Micro Diver is the smallest Diver capable of accurately recording groundwater levels and temperature. The Micro Diver is specifically designed for monitoring wells too small to accommodate larger data loggers.

The Micro Diver is perfect for use when performing pump tests or well recharge monitoring. Designed to fit safely inside a 19mm slotted PVC pipe, so you no longer have to worry about cables getting tangled or your logger being damaged during pumping or bailing.

In addition to its compact size, the Micro Diver’s memory capacity can store up to 48000 measurements per parameter – almost one measurement every ten minutes
for an entire year.
