1. Introduction
The IJ series of electrodes are designed to be
versatile, robust, reliable, accurate and long
lasting. The IJ
“intermediate junction” reference
system addresses an uncertainty in
potentiometric measurement i.e. the condition
of the contact zone between the reference
electrolyte and the sample, which affects
accuracy. This is achieved by an easily
removable reference sleeve which allows
frequent, easy and effective cleaning of the
junction
surrounding the contact zone.
Interchangeable reference sleeves are
provided: unprotected for direct insertion into
semi-solid samples (meat, cheese, wet soils
etc.), and protected for non-viscous samples. IJ
electrodes are fully waterproof; allowing full
immersion including the cable to 10m.
