The TD-Diver is acknowledged as the most reliable instrument for the autonomous measuring and recording of groundwater level and temperature. It's available in the following pressure ranges: 10 m, 20 m, 50 m and 100 m.
The TD-Diver is a compact groundwater monitoring instrument for the continuous and autonomous measuring of level and temperature in groundwater, surface water, and industrial waters. This model succeeds the mini-Diver and offers a completely new design, which combines over 75 years of groundwater monitoring experience with the latest technology available in the market today.
The instrument samples pressure and temperature at fixed length intervals and stores these values in fixed length or continuous memory. For each measurement, the TD-Diver registers the date and time, groundwater level, and temperature. The data collected can be used to manage water resources, estimate hydraulic conductivity and other aquifer conditions.
This easy-to-use datalogger features state-of-the-art electronics and a robust high-precision pressure sensor for long-term accuracy. The absolute pressure sensor requires minimal maintenance and re-calibration.
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.
Its internal memory of 72,000 measurements per parameter provides sufficient capacity to perform one measurement every 15 minutes for over 2 years. Connect the diver to a modem to transmit collected data directly from the field to your data centre.
