Refillable Combination pH Probe
The MA918B/1 is a lab grade refillable glass electrode with a conic tip designed for fast accurate measurements in all applications.
Triple Junction
The triple reference design reduces risk of clogging with the reference cell physically separated from the intermediate electrolyte.
Refillable
The MA918B/1 is refillable with MA9011 3.5M KCl+AgCl electrolyte. 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.
Glass Body
The glass body is easily cleaned and resistant to chemicals.
Conic Tip
The conic design of the tip provides the largest possible surface area for faster readings and is well suited for testing in many applications.
