pH Combination Electrode





Fitted with coaxial cable and BNC (Bayonet Neill-Concelman) type SL-31 connector.

The combined Electrode consists of glass and reference electrodes in a single entity. Therefore a separate, reference electrode need not be used along with this electrode. Below the cap of the electrode a hole is provided for filling the solution in the internal reference electrode. The reference electrolyte solution or filling solution is a freshly prepared 2 M Potassium Chloride (KCl) Solution.

Preparation for Use

Soak the glass bulb and the fibre junction of the electrode in N/10 Hydrochloric Acid for 24 hrs to activate the sensing membrane. Then rinse the bulb with distilled water a number of times. Never use ordinary tap water.

Preparation of N/10 Hydrochloric Acid

Take 1 ml of concentrated Hydrochloric Acid and dissolve it in 100 ml of double distilled water.

Shake the solution inside the electrode to let it fall into the bulb. Fill the electrode with freshly prepared 2 M Potassium Chloride solution into three fourth.

Preparation of 2 M Potassium Chloride Solution

Dissolve 14.91 g of A.R. KCl in 100 ml of double distilled water and add a few crystals of A.R. AgCl

Instructions provided with electrodes.
