Engineers and technicians searching for a high-performance oxidation-reduction potential (ORP) sensing solution will find that the S10 and S17 ORP Sensors from Electro-Chemical Devices (ECD) feature a no-glass design with platinum or gold sensor tips to operate safely in a wide range of applications. ECD’s ORP S10 and S17 Sensors come with easily replaceable ORP cartridges that plug into a rugged 316 stainless steel body, which incorporates the sensing element, a temperature module, and a signal conditioner with cabling. The S10 is an immersion or insertion style sensor, and the S17 is a valve-retractable style sensor.

ECD’s ORP electrode cartridge features rugged PEEK (polyetheretheketone) construction and measures from –2,000 to +2,000 millivolts over a wide temperature range of 23F to 176F. The ORP sensors are available with the SENTINEL option to monitor the reference electrode potential and display measurement drift graphically and/or with a 4-20 mA output providing a predictive maintenance alert before reference electrode degradation causes problems to occur.
