The Oakton 35608-50 is a conductivity/Total Dissolved Solid (TDS) electrode, with cell constant of K=1.0 for mid-range conductivity measurements. The electrode, also known as a probe, measures the conductivity and TDS of a solution, and is commonly used in testing water, such as pure and sea water, in field and laboratory applications. This probe features stainless steel sensors for specific application, Polyetherimide (PEI) ultem-body housing for chemical resistance, and an 8-pin DIN connection for stability. It comes with a removable, plastic probe guard to preserve the unit.

The 35608-50 electrode has a temperature range of 0 to 80 degrees C (32 to 176 degrees F) and is used for mid-range conductivity measurements. Its dimensions are 100 (l) x 12 (d) mm. It is intended for use with the Oakton CON 400, and meters that have 5-pin Deutsches Institut für Normung (DIN)-connections (sold separately). It comes with a 3-foot cable.

An electrode is used with a meter to measure the parameters of a substance. Conductivity is the ability of a solution or material to conduct an electrical current. TDS measurement indicates materials such as salts, bases or minerals, which contribute to electrical conductivity, within a solution.

Calibration:
Calibrate according to meter instructions. Always use fresh calibration standards. Select a calibration standard value that is close to your sample value.

Measurement:
Avoid air bubble entrapment by gently tapping electrode to dislodge. Ensure sensors are completely immersed. Rinse with clean water after each use.

Cleaning:
If the electrode has been stored dry, soaking in alcohol or clean water for a few minutes can help performance.
