Van Essen Instruments TD-Diver Datalogger 11.7 Lamp TEMPERATURE RANGES - Operational: -20Van Essen Instruments TD Diver Datalogger TD Diver, the industry standard water level datalogger. The TD 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 Diver autonomously measures
