Electro-Chemical Devices S10 and S17 Analytical pH Sensors

Electro-Chemical Devices’ S10 and S17 Analytical pH Sensors monitor pH in water-based solutions and are sulfide-resistant. The sensors’ replaceable cartridge electrode features a pH range of 0 to 14 at temperatures from -5 to 130°C and survives pressures up to 300 psi at 25°C. It has been tested to sulfide ion concentrations of up to 25 ppm.

The product line consists of two sensor designs and replaceable electrode cartridges. The S10 Sensor is an immersion- or an insertion-style sensor, and the S17 is a valve retractable-style sensor. They are fully rebuildable and feature a 316 stainless steel body that incorporates the sensing cartridge, a temperature module and a signal conditioner with cabling.  

The cartridges provide specific solutions for the measurement of pH, ORP, specific ion (pION), dissolved oxygen, conductivity and resistivity in a wide range of industrial process applications.

The pH and ORP cartridges are available with either Radel (PES) or PEEK construction configurations with full crown, double or single tine-style pH bulb protection. The pION cartridges with solid-state, glass or PVC sensing membranes are suitable for continuous online measurement. The DO electrode is a galvanic cell with a lead anode, silver cathode and Teflon membrane. The conductivity and resistivity electrodes are designed in both contacting and toroidal sensor configurations for application flexibility.

The immersion/insertion sensor is designed with a 0.75″ MNPT compression fitting. The retractable sensor is designed with a 1″ MNPT ball valve, a 1-x-0.75″ reducer and a 0.75″ MNPT compression fitting.
