Origin of Precision.

A combination pH electrode with a plastic shaft, ring junction and a fixed cable. Designed for soft water like surface water or drinking water.

Stable reading in ion-poor samples

High electrolyte outflow reduces the potential at the junction, which in turn supports more stable readings.

IP67 - For a water-proof measurement

Ensures your entire portable measuring system (Seven2Go meter and InLab sensor) is able to withstand wet and demanding environments.

Spill free wetting cap Easy-to-use wetting cap with a self-tightening screw lock that guarantees clean and secure electrode storage.
