Partech - Model WaterTech pH & ORP -Combined Sensor
FromIn-Situ Process
The WaterTech pH & ORP Sensors has been designed to provide highly reliable pH, Redox and Temperature measurements. The sensors use a flat surfaced electrode which includes an extended reference path, these features combine to provide extremely robust pH & Redox measurements, suitable for use in surface water, wastewater and drinking water applications.
The electrode uses field-proven flat surface, self-cleaning technology. The reference system is enhanced by the Extended Path Reference (ERP) design which provides a complex path to protect the reference in the presence of interacting ions such as proteins, silver and sulphides.Most popular related searches

- Periodic cleaning is required at a frequency determined by the application. Our self cleaning shaft option is highly recommended, this eliminates manual cleaning between calibrations.
- Calibration : The sensor is inherently stable, calibration should be carried out to suit the application. Our recommendation is every 6 months.
