pH Water Quality Sensor Description

The STs Series pH water quality sensor is designed to meet and accomodate your application requirements by providing years of trustworthy pH and temperature data via noise-resistant 4-20 mA signals. The sensor has a large, double junction reference electrode for stable measurements over long periods of unmanned operation. In addition, our noise-reduction technology prevents ground loops and other forms of electrical interference for consistently accurate measurements. A narrow diameter (0.75” or 1.9 cm) and fully sealed, submersible design allows the sensor to go anywhere you need to collect data while the durable, chemicalresistant housing and Kevlar-reinforced® cable ensure many years (10+) of operation, even in polluted environments.
