Model ST956

ST956 Submersion & In-Line DynaProbe pH and ORP Sensors with Solution Ground

The ST956 is a rugged, sealed sensor assembly designed for in-line or submersion applications. The patented solid state reference cell features the unique IonTrap® design for extended service life in the most severe applications. The body, with an integral 3/4″ MNPT insertion thread, is moulded from chemically resistant Ryton (PPS) and the reference junction is porous Teflon. Built-in temperature compensators are available. Features include built-in sensor guard that protects the sensor tip from impact. Sensor also available in Redox (ORP) version.

Application: Used in aggressive & corrosive application. Also with special selection can be used in Hydroflouric Acid (HF).
