Refillable Combination pH Probe for Milwaukee Type M917

Milwaukee MA917 Refillable Combination pH Probe DOUBLE JUNCTION The double junction design reduces risk of clogging with the reference cell physically separated from the intermediate electrolyte. REFILLABLE 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. GLASS BODY The glass body is easily cleaned and resistant to chemicals. ROUND TIP The round design of the tip provides the largest possible surface area for faster readings and is well suited to testing liquid samples.
