Reference system:
When no specific mention applies, 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).
Fluid conductivity must be over 50 μS/cm

pH combined electrodes:
Glass and reference electrodes are always as a combination system.
The measuring electrode is totally protected by the surrounding low resistive electrolyte from the reference electrode. The measuring area corresponds to special glass bulb end.

ORP combined electrodes:
For these electrodes, the glass bulb is replaced by a metallic element, in platinum or gold. Gold is mainly used for ORP measurement in liquids containing cyanides.

All our electrodes have a S8 plug to receive a coaxial connector ref. 9054. Safe fitting and water tightness are ensured with a threaded connector type Pg 13.5.
Our industrial electrodes fit on dedicated electrode holders, in order to protect them and for optimized measurements.

For immersion in tank please see the data-sheets 130-01, 135-01 and 145-01.
For in-line flow through cells see the data-sheets: 140-01, 140-02, 141-01 and 142-01.
