Replacement Potassium Sensor for NPK Meter – Coming Soon

Solid State Potassium sensor with integral 2mm pin connector. This sensor fits directly into the NPK Sonde as a replacement item.

The solid state sensors have a huge advantage over conventional ISEs because there is no internal fill solution to degenerate the sensor. This means that EDT directION ISEs have an un-rivalled lifetime and a very low cost of ownership.

The technical specifications are identical to the standard Potassium  ISE 1031 and requires a separate reference electrode compatible with the NPK Sonde.
