Model 397 TUpH® Sensor & the Quick-Loc Kit

---

THE TUpH® MODEL 397 pH SENSOR OFFERS: EXCELLENT PERFORMANCE in process solutions with a high solids content. LONGER SENSOR LIFE and reduced maintenance due to the industry proven patented polypropylene reference junction and helical reference pathway. AccuGlass® pH glass formulation for maximum glass performance. INSTRUMENT COMPATIBILITY with Rosemount and other manufacturers’ instruments. THE QUIK-LOC KIT OFFERS: QUICK AND EASY ACCESS to Model 397 pH sensor without cable twisting. VISUAL CONFIRMATION that the sensor is locked into position.

FEATURES AND APPLICATIONS The low maintenance Model 397 pH sensor offers long life and high performance in the measurement of pH in aqueous solutions with high suspended solids. The Model 397 is housed in a highly chemical resistant polypropylene body and is completely sealed with EP (ethylene propylene) to eliminate process intrusion. This TUpH® sensor features a patented, large area, polypropylene reference junction¹ for maximum resistance to process coatings, generally found in harsh, dirty and high solid applications. In addition, the patented secondary helical reference pathway² serves as added protection from poisoning ions. The Model 397 features AccuGlass® and a large glass bulb for increased resistance to the effects of aging for longer life. The sensor is specifically designed for use with the Quik-Loc Kit and is only available without an integral preamp. The preamplifier must be in a remote location or integral to the analyzer/transmitter. ¹ May be Protected by U.S. Patent No. 5,152,882, Foreign Patent Pending ² U.S. and Foreign Patents Pending AccuGlass® is a registered trademark of Rosemount Analytical, Inc.
