The Chemtrol® pH Sensor NSF 50 is built for rugged pH and ORP applications, featuring an impact-resistant epoxy body for durability. It ensures precise readings with an Ag/AgCl gel-filled, sealed reference and dual ceramic pin wicks, reducing maintenance needs.
Designed for fast and accurate response, the pH electrode uses a GP bulb glass for reliable measurements across a 0–12 pH range. The ORP electrode integrates a solid platinum band fused to the glass bulb, optimizing performance.
This sensor operates continuously between 0–60°C and can withstand intermittent exposure up to 100°C. With a maximum pressure tolerance of 60 PSI, it is suited for demanding environments.
A low-noise coaxial cable with dual shields ensures stable signal transmission and compatibility with Chemtrol controllers. This makes it a dependable choice for pools, spas, and industrial water treatment.
