VanEssen Baro-Diver Hardness Tester The sensor is a completelyThe Baro Diver is a datalogger for long term uninterrupted, real time atmospheric pressure monitoring. In addition, the Baro Diver can monitor shallow water levels 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 pressure and temperature and records
