Replacement Nitrate Sensor for NPK Meter

Solid state Nitrate Sensor with integral 2mm pin connector and a green colour coded tip.

This sensor fits directly into the NPK Sonde as a replacement item. The sensor should be placed into the Sonde head in the N position and pushed in using a twisting action so that the O-ring seats snuggly into the holder.

The probe will require 10-20 minutes conditioning in MultiCal 1 Solution prior to use. 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.
