Compact Size
Measuring only 88 mm (3.46") in length and 18 mm (0.71") 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 or drive-points too small to accommodate larger dataloggers.
In addition to its compact size, the Micro-Diver’s memory capacity can store up to 48,000 measurements per parameter - almost one measurement every ten minutes for an entire year.
