Description
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.
Features
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.
Compact size: diameter of 22 mm and length of 110 mm
Memory: 72,000 records of time stamp, pressure and temperature with back-up of 72,000 records
30-Point Pressure Factory Calibration
Corrosion-proof ceramic pressure sensor
Continuous and fixed length memory
