Honeywell HB551 Quick Change pH Sensor

Quick Change pH Sensor

The HB551 pH electrode offers a reliable combination of measuring and reference electrodes together with an integral automatic temperature compensator in a 1-piece corrosion resistant body (the body material is chosen by the customer). The HB551 pH electrodes are designed for quick-change in-line installations. The HB551 can also be used in submersion operations. The HB551 pH electrode is a quick change sensor.
