Overview
Rosemount™ 3900 General Purpose pH/ORP Sensor with Variopol (VP) ConnectionThe Rosemount 3900VP General Purpose pH Sensor / ORP Sensor features a double junction reference that aids in the pH/ORP sensor's resistance to harsh environments and helps prolong sensor life. The double junction protects the reference element from poisoning ions - such as ammonia, chlorine, cyanides, and sulfides. The pH/ORP sensor is made with a porous Teflon® junction. The robust pH/ORP sensor design makes the Rosemount 3900VP pH/ORP Sensor a reliable choice for a wide range of aqueous solutions found in pipelines, open tanks or ponds.
Benefits
* Extended pH sensor/ORP sensor life and protection against poisoning ions using a double junction reference
* Enhanced performance and increased life with cracking resistant glass
* Maximum chemical resistance provided by a rugged polyphenylene sulfide body
* Operates in sub-zero temperatures down to -10°C (14°F)
* Built-in solution ground for advanced diagnostics
* pH/ORP sensor body features a one-piece construction with both front facing and rear facing process threads
* ¾” and 1” MNPT process connections to meet a variety of application installation requirements
* Variopol (VP8) cable connection option, for quick cable-to-sensor release, eliminates cable twisting
* SMART enabled for pH measurements
