01Overview
What It Is.
pH governs inhibitor performance, scaling tendency and biocide effectiveness; ORP indicates whether the water is currently in an oxidising state. Both are only as good as the electrode’s installation and calibration discipline.
02Key Benefits
Why It Is Specified.
Construction matched to duty
Differential constructions for fouling or high-conductivity duty; high-temperature bodies where process conditions demand.
Predictable service life
An electrode selected for the actual chemistry lasts longer and drifts less between calibrations.
03Applications
Where It Is Used.
- Cooling water pH control
- Halogen feed control by ORP
- Effluent neutralisation
- Process water monitoring

C-Water specifies the measurement points, sets the control strategy against the actual treatment programme, commissions the loop and supports it in service. The instrument is the tool; the control philosophy is the engineering.
