TEMPERATURE/LEVEL/CONDUCTIVITY SENSOR The OTT PLS-C unit provides basic water quality indicators by measuring water level, temperature and conductivity. The probe is suitable for measuring both surface water and groundwater, with its high-quality and robust equipment ensuring easy operation and long-term precise readings. Low power consumption makes the product suitable for long-term deployment, particularly at solar-powered measuring stations. The precise ceramic capacitive pressure cell withstands mechanical impacts
