The Oakton WD-35801-71 is a single-junction, 12-mm, gel-filled, pH electrode, with an epoxy body, and pH sensor models of 0 to 14 for high sodium/pH solutions. The electrode measures the pH of a solution and is commonly used for field, clean water and general purpose applications. It is an all-in-one, standard electrode with a combination pH electrode/temperature sensor. It features a built-in temperature sensor for ATC, has a single-junction for general purpose applications, and a pin-type junction for low electrolyte flow and longevity. It has an epoxy body for impact resistance and durability. The electrode houses a gel-filled electrolyte to enhance performance, and has a BNC connector to provide a tight coaxial cable connection and stability. It comes with a protective electrode storage bottle to prevent damage.

This 35801-71 electrode has a temperature range of 0 to 80 degrees C (32 to 176 degrees F), an Ag/AgCl reference solution, 12-mm diameter, and features a 30-inch cable. It is intended for use with pH 10/100/500/1000/2500 meters.

pH testers measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists in hydroponics, aquaculture, agriculture and wine-making.

We are really pleased with this electrode. We could not find a replacement thru our typical ordering systems, but we had no problem thru Amazon. It was brand new and works well. Now we can continue to make compounded medications. Grandpa's Compounding Pharmacy- Placerville California.

Found a very nice discontinued Ph meter on ebay for dirt cheap and needed to pick up the probe to complete the package. The only thing I could find was almost twice the price of this unit. So far so good though, been taking weekly measurements with this guy for over a year now and I expect it will last me another 10 years at least, just make sure you keep the probe in calibration solution! Otherwise Oakton makes quality products and I can't complain at all.If you need a new probe and need a great price then I wouldn't hesitate to consider this unit.

Bought this to replace a pH meter in the lab in which I work. Worked great and the price could not be beat. Please note that this is not a stand alone pH meter. You need the portable unit (where you plug this into) to be able to use it.
