Overview
Rosemount™ 389VP General Purpose pH/ORP Sensor
The Rosemount 389VP pH Sensor / ORP Sensor is housed in a molded Tefzel™ body with Viton™ o-rings, making each sensor virtually indestructible and chemically resistant. Complete encapsulation eliminates leakage or high humidity problems traditionally found in other pH/ORP sensor designs. The simplified construction, designed with user convenience in mind, does not require electrolyte (KCl) replenishment or any high maintenance troubleshooting procedures.
Benefits
* Triple junction reference prolongs pH sensor/ORP sensor life and protects against poisoning ions such as ammonia, chlorine, cyanides, and sulfides
* Enhanced performance and increased life with cracking resistant glass
* Available with a glass electrode option for high pH applications
* Superior chemical resistance provided by a rugged Tefzel body with Viton O-rings
* The molded sensor body features 1” MNPT front and rear facing process connections for insertion, submersion, and flow-through applications
* Variopol (VP6) cable connection option, for quick cable-to-sensor release, eliminates cable twisting
* SMART enabled for pH measurements
