INDUSTRIAL APPLICATION ELECTRODES
INSTRUCTIONS NOTE
 Electrodes
Reference System
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).
PH Combination Electrodes
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.
ORP Combination Electrodes
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 Other information about combination pH electrodes is applicable on ORP combination electrodes.
Electrodes
Electrodes are combined gel filled (no filling up is necessary).
Dimensions
All electrodes are 12 ±0.5 mm external diameter, fitting with thread connection and electrical plug for a specific 9054 connector.
A Pg 13.5 connection insures the perfect sealing.
Mounting
Any industrial electrode must fit on an adapted electrode holder, in order to protection it and to optimize the measurements.
- For immersion in tank or open channel flume, please see the documentation 130, 135 and 145.
- For in-line flow through cells please see the documentation 140 and 141.
Please Note: Electrode must always be immersed in liquid.
