Micro Diver

The Van Essen Micro-Diver is the smallest data logger designed to measure and record groundwater levels and temperature. Measuring just 88 mm in length and 18 mm in diameter, this compact device is ideal for pipes with a diameter of at least 20 mm and is particularly well-suited for pumping tests.

This autonomous data logger is available in measuring ranges of 10 m, 20 m, 50 m, and 100 m and can store up to 48,000 measurements per parameter, providing nearly one measurement every ten minutes for an entire year. You can also connect the Micro-Diver to a modem to transmit collected data directly from the field to your data centre.
