Replacement Nitrate Sensor for NPK Meter – Coming Soon


Out of stock

SKU: 2021/NPK Categories: ,

Solid State Nitrate 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 Nitrate ISE 1021 and requires a separate reference electrode compatible with the NPK Sonde.
