3900/3900VP General-Purpose pH/ORP Sensor
Brand: RosemountThe Rosemount 3900 pH/ORP combination sensor's double junction reference aids in the 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.
Both sensors are made with a porous Teflon® junction. The robust sensor design makes the 3900 reliable in a wide range of aqueous solutions found in pipelines, open tanks or ponds.
Features- Extended 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
- The sensor body features a one-piece construction with both front facing and rear facing process threads
- ¾” and 1” Male NPT 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
