If there is not a special mention, all our electrodes use a reference system as Ag/AgCl with a porous reference junction in ceramic: theoretical zero is at pH 7 (0 mV). Theoretical gain is close to 58 mV per pH units (at 20°C).

Glass and reference electrodes are always as a combination system. The glass electrode is totally protected by the surrounding low resistance electrolyte from the reference electrode. The measurement area corresponds to axial centered wire. 

For these electrodes, the glass bulb is replaced by a metallic ring, Platinum or Gold, according to the application. Gold ring electrodes are mainly used for ORP measurement in liquids containing cyanides. 

All our probes have a 12 mm outside diameter and are 120 mm long. They are fitted with an S7 plug for our coaxial connector ref. 9054. Water tightness is handled with a threaded connector type Pg 13.5. 

Any industrial electrode must fit on an adapted electrode holder, in order to protection it and to optimize the measurements.
