The miniaturised data logger T-Log3001 was specifically designed to measure temperature inwaters. In addition to its pressure resistance up to 100 metres water column it offers high accuracy and resolution as well as a large memory. The logger housing is made of stainless steel V4. If you have to undertake measurements in aggressive fluids the T-Log3001 can also be delivered with a plastic housing (for depths of up to 30 m).

The O2-Log3050 is a data logger for dissolved oxygen and temperature. It measures the oxygen saturation level in the water and saves the readings to its internal memory. It also calculates the ppm and mg/l concentration and allows for user-friendly recalibration and changing of its O2 electrode. In combination with its automatic temperature compensation it is best suited for operation in lakes, rivers, in sewage-treatment plants or for monitoring transportation, e. g. of fish.

The pH-Log3030 is a self-sustaining data logger for unsupervised measurements and logging of pH and temperature. It is perfectly suitable for water quality surveys, e. g. in bodies of water or sewer tunnels, or for monitoring in transportation, e. g. fish or fluids. Once the pH Log3030 has ben set up with a PC it records measurements of the chosen parameters in a freely programmable interval.

The μS-Log3040 can measure conductivity and temperature in aqueous solutions at the same time. Typical fields of application are monitoring wells, rivers, lakes and sewer tunnels or transportation, e. g. of fish.

The P-Log3021-MMC was specifically developed for applications demanding an increased memory capacity and high sampling rates. The measurement of the water level is carried out based on a piezoresistive pressure sensor and the measurement of the temperature is achieved by a high-precision measuring resistor. Its exceptionally high resolution and accuracy allow for water level and wave movements to be measured accurately to the very last millimetre.

The models P-Log3020 PA (=absolute pressure) and P-Log3020 PR (=gauge pressure) are data loggers capable of measuring water level with an accuracy of a few millimeters and also water temperature. Highlights of these data loggers are their high resolution as well as large memory. They offer a high long-term stability and provide reliable measurements over many years without a battery change thanks to an optimised energy consumption.
