Electrodes for Laboratory and Field

Applications

All Oakton

electrodes have a BNC-connected combination

reference cell and measuring cell in one housing for easy use

Oakton offers a variety of electrodes for your general-purpose and specialty laboratory applications. The

“Application Guide” below provides information to help you find the electrode that best fits your application.

Carefully choose the electrode best suited for your application to ensure accurate pH measurements. The guide

only offers suggestions—contact your Oakton Technical Product Specialist for more specific recommendations

or clarification. Shipping dimensions for all electrodes are 9.25" x 1.75" x 2.75". Shipping weight 0.5 lb each.

Use and Care of Electrodes

Handling—Electrodes should be rinsed between samples with

distilled or deionized water. Never wipe an electrode—wiping can

cause erroneous readings due to static charges. Gently blot the end of

the electrode with lint-free paper to remove excess water.

Refillable Electrodes—see page 32 for reference solutions.

The filling solution in refillable electrodes should be filled up to, but

not past, the refill hole. Make sure the refill hole is left open when

measuring to ensure that the fill solution flows properly through the

reference junction.

Storage—see page 29 for storage products.

Always keep your pH electrode moist. We recommend that you store

your electrode in an electrode storage solution of 4 M KCl (see page

29). If 4 M KCl is not available, use a pH 4 or 7 buffer solution. DO NOT

store electrode in distilled or deionized water—this will cause ions to

leach out of the glass bulb and reference electrolyte, rendering your

electrode useless.

Temperature Probes

Order a temperature probe if you have an electrode without

a built-in temperature sensor and you want to take readings

with Automatic Temperature Compensation (ATC). Separate

temperature probes offer faster temperature response and

lower pH electrode replacement cost.

Oakton electrodes are shipped with a protective electrode

storage bottle to help prevent cracking or scratching, and to

keep the bulb moist. Remove the electrode storage bottle before

using your electrode. Keep your electrode in the bottle for

long-term storage—just fill the bottle with enough 4 M KCl

solution to cover the glass bulb and replenish as needed.
