HB Series pH/ORP Electrodes

Honeywell’s HB Series of electrode mountings are designed for high temperature, high pressure and harsh chemical applications. The HB Series electrodes offer the unique Axial Ion Path (patented by Barben Analyzer Technology) reference technology.  Axial Ion Pathways prevent poisoning Axial Ion Path sealing rings prevent internal plugging and insure against internal leaks Glass breakage and leak pathways during manufacture eliminated - no more DOA sensors Complete filling of reference body allows extreme temperature and pressure tolerance Non-polymerized electrolyte insures compatibility with all chemistries Large-area, liquid junction slows the buildup of coatings and reduces sensor drift Long life in both low and high pH applications The HB Series of electrodes has three designs: HB546 is designed for threaded in-line or submerged operations. The HB546 is designed with 3/4" MNPT threaded nose for installation into process, sample line or automatic cleaning system.  The insertion depth user specifiable to ensure the sensor will fit into the process. HB547 is designed for use with specified ball valve assemblies. The electrode is available with 1” MNPT Wrench-tite, or 1-1/4” MNPT Hand-tite compression fittings. HB551 is designed for use as a quick change sensor. 1” MNPT threaded adapter for installation into process, sample line or automatic cleaning system. The HB551 sensor comes with a nut-loc retainer for quick removal and replacement. The HB Series of electrodes join Honeywell’s industry-proven Meredian glass pH electrodes and Durafet ISFET (glass-free) pH electrodes to offer a complete solution for all pH needs.
