Process and plant engineers seeking a lower cost and maintenance solution will find the answer with the advanced Sentinel predictive maintenance technology from the T80 Universal Transmitter and S80 Intelligent Sensors. This technology alerts maintenance technicians to sensor electrode (pH, ORP, selective Ion) wear so that sensor electrodes are replaced only as necessary. Sensor replacement costs and labor time are reduced to the optimum level, water quality remains constant and other related equipment and systems continue to perform at high levels.
