Replacement electrode for Hanna pHep 4 (HI 98127) and pHep5 (HI 98128) pH meters. Also replacement for pH electrode of Hanna COMBO meters, HI 98129 and HI 98130
The Hanna electrode replacement has a stainless steel round connector which means there are no pins to bend or break during replacement. The replaceable electrode has a pull-out cloth junction. When the cloth junction becomes dirty from routine testing, simply pull out 3 mm (1/8") to rejuvenate the electrode. Tool is required if you need to replace your electrode.
