ORP (Redox) Water Quality Sensor Description
The STs Series ORP water quality sensor makes your job easier by providing years of trustworthy ORP and temperature data via noise-resistant 4-20 mA signals. It does so with a large, double junction reference electrode for stable measurements over long periods of unmanned operation. In addition, pHionics 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.
Ranges available
• -1000 to +1000 mV
