Measuring only 88 mm in length and 18 mm in diameter, the Micro-Diver is the smallest Diver capable of accurately recording groundwater levels, surface water levels and temperature. Suitable for pipes with a diameter of at least 20mm. These instruments are more narrow, and suitable for pumping tests.
The Micro-Diver measures autonomously and 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. Connect the diver to a modem to transmit collected data directly from the field to your data centre.
The datalogger is housed in a stainless steel cylindrical casing, with a suspension eye at the top. The suspension eye can be unscrewed and is designed to install the Diver into the monitoring well and protect the optical connector. The electronics, sensors and battery are maintenance-free and installed into the casing. The Diver is not designed to be opened.
Special software is available for the Divers. Download via WeTransfer.

Where there is a need to monitor groundwater levels and salt water intrusion, injected wastewater, or contamination from chemical discharges and landfill sites, the CTD-Diver with its 22 mm diameter rugged corrosion-proof ceramic (zirconium-oxide) housing is the instrument of choice.
The CTD-Diver is a submersible datalogger 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 ceramic casing is suitable for brackish or saltwater applications as well as aggressive environments.
Connect the diver to a modem to transmit collected data directly from the field to your data centre.
Features
The CTD-Diver is an ideal choice for ground and surface water level applications. The water logger is equipped with a four-electrode conductivity sensor that measures electrical conductivity from 0 to 120 mS/cm. This type of measuring cell is relatively insensitive to sensor fouling, thus keeping maintenance to a minimum.
