Product Description

HR***3 Integrated pressure water level Transmitter
1.Overview
HR***3 is a three-parameter (water level, water temperature, conductivity)integrated pressure water level gauge, working with a digital barometer, which can be either external powered or internal battery self-powered, it is used for the long-term recording of the depth (pressure) and the temperature.  It is all stainless steel structure, which contains water level sensor, temperature sensor and conductivity sensor, built-in large-capacity non-volatile memory and high-capacity long-life lithium battery, it is suitable for three-parameter hydrological parameter measurement of surface water, groundwater and marine environment.
