Overview
Consort offrs a wide variety high quality electrochemical analytical sensors. Our pH, ORP (Oxidation-Reduction Potential),
Conductivity, Oxygen and Ion Selective Electrodes (ISEs) are designed for Laboratory, Industrial, Biotechnology and Medical
applications.
The most common electrodes are in our catalogue. We can supply variations depending on your needs: body style, submersible,
cable length, body length, connector type, ATC type,…
Most of our electrodes can be delivered from stock. ISE’s are never delivered from stock because of it’s limited shelf life. An ISE is
manufactured on demand and as such will guarantee an ideal shelf life combined with a low price.

Tips and tricks
While calibrating or measuring, all solutions should be stirred gently to ensure the electrode gives a true representation of the beaker
contents.
Calibration solutions with values near the expected sample value should be chosen. Only fresh calibration solutions should be used.
Changing all solutions daily is a good practice. All solutions should be maintained at equal temperature.
Rinse the electrode twice between measurements: fist thoroughly in distilled water and then with a small amount of the next sample
to be measured. Allow the electrodes suffient time to stabilise while calibrating or measuring. A stability indicator on all of our meters
prompts the user when readings should be taken.

Special electrodes
Glassless pH electrodes SP40
Our NEW Liquid pH or LpH sensor is specially designed so that there is no glass in contact with the
solution being measured. Conventional glass pH electrodes are quickly etched and destroyed by HF
and as a result, current glass pH electrodes for HF applications use an extra thick membrane causing
slow sluggish response time. This is not the case with the SP40!
SP40 is an exact replacement for conventional glass pH electrodes. The SP40 is available in
Laboratory 12mm design with double junction reference for extended probe life.

Ion selective electrodes Supplied with 1 m of cable and BNC plug
Polymer electrodes consist of various ion-exchange
materials in an inert matrix such as PVC, polythene or
silicone rubber.
Solid state electrodes utilise relatively insoluble
inorganic salts in a membrane.
Glass membrane electrodes are formed by the doping
of the silicon dioxide glass matrix with various chemicals.
Two versions available:
• Sealed (ISE20B…ISE37B)
• Refilable with replaceable membrane (ISE60B…ISE77B)
Gas sensing electrodes are available for the measurement of ammonia, carbon dioxides and nitrogen oxides. These electrodes have a
gas permeable membrane and an internal filing solution.
One versions available:
• Flat replaceable membrane (ISE50B…ISE52B)
All models are combination electrodes and have an epoxy body.
