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

• -1000 to +0 mV

• -500 to +500 mV

• +0 to +1000 mV

This ORP (Redox) water quality sensor comes standard with 25ft cable and 316 stainless steel housing, a titanium version is avaialble for harsh chemical conditions, additionally, each sensor can be purchased with any cable lenght, up to 1,000ft.
