Engineers and technicians looking for a flexible, cost-effective solution to monitoring sour water containing Hydrogen Sulfide (H2S) compounds in oil/gas refineries will find the sulfide-resistant Models S10 and S17 analytical pH sensors from Electro-Chemical Devices (ECD) help them keep their processes and plants running efficiently. ECD’s S10 and S17 pH Sensor product family monitor pH in water-based solutions. The S10 and S17’s Model 20005130 replaceable cartridge electrode features a pH range of 0 to 14 at temperatures from -5 to 130 oC and survives pressures up to 300 psi at 25 oC. It has been tested to sulfide ion concentrations of up to 25 ppm.
