Combined glass pH electrode, double junction, refillable, BNC connector, 1 meter cable
The MA917B/1 refillable with MA9011 3.5M KCl. This solution is sliver-free. Sliver can cause silver precipitate to form at the junction resulting in clogging. Clogging causes erratic and slow readings. The ability to refill the electrolyte also extends the life of the electrode.
