Introduction

I got an Ion Selective Electrode (ISE) from Aliexpress.

More advanced version available from e.g. Pasco scientific, Mettler Toledo and Thermo Fisher.

The simple NO3 ISE

Bante-instruments

The series of ISE’s offered from Aliexpress are from Shanghai INESA Scientific Instrument Co., Ltd (REX?), including the PNO3-1-01 sensor. The webpage of INESA/REX does not contain any more specification on the sensor.

However, the company BANTE instruments sell the same type of NO3- ISE sensor and also offer a suite of manuals for ISEs. The manual for the NO3- ISE

For calibration a solution of NaNO3 (sodium nitrate)
