Specifications and Features
2714-2717 pH/ORP Electrodes
Signet 2714-2717 pH and ORP Electrodes provide unsurpassed simplicity, reliability and accuracy for a wide variety of industrial applications. Rugged CPVC construction, large reference volume and intelligent positioning of internal elements combine to extend the service life of these dependable and highly responsive sensors. Flat versions allow sediment and particles to sweep past the measurement surface, minimizing risks of abrasion, breakage and coating.
The unique twist-lock design enables sensor connections in one easy motion. This includes the integral temperature sensor in pH electrodes, and the I.D. circuit in ORP electrodes. These contacts are used for automatic sensor recognition by Signet pH/ORP Instrumentation, adding convenience and versatility to our systems.
