Reliable pH probes and redox probes are an integral part of any monitoring system providing feedback at all times accurate readings which the instrument is dependant upon to maintain chemical levels in the system and the control dosing pumps. A robust design with low maintenance requirements sensors and electrodes suitable for all types of environments and applications.

High performance robust pH electrodes and redox electrodes with either PG 13 connection or with the coaxial cable connected direct to the electrode itself, providing a accurate reading back to the monitoring instrument which depends on stable and consistant signaling from the electrode for all types of process environments and water treatment applications.

pH Probes

Redox Probes

pH Probe & pH Electrode Measurement

The measurement of Hydrogen Ion concentration in an aqueous liquid, which determines whether a liquid is neutral (7.0 pH), acid or alkali. pH is usually measured with a glass or plastic combination electrode which produces a millivolt potential proportional to the pH value that is amplified by the software inside the pH instrument to give an instantaneous value.

 

Redox Probe & Redox Electrode Measurement

Typically used to determine the oxidizing or reducing potential (ORP) of a water sample solution being a measure of the tendency of a chemical species to acquire electrons from or lose electrons to an electrode and thereby be reduced or oxidised respectively, using a platinum tip electrode with the the value being presented millivolts (mV), the term Redox is derived from Reduction Oxidation and also be referred to as ORP (Oxidation Reduction Potential).

 

All controllers incorporate control relays as well as a (0) 4-20mA signal. Depending on which model of controller - these can be used to control a piece of control equipment such as a pump or solenoid valve. Often these pieces of control equipment can be controlled proportionally that is - causing the device to speed up, or dose faster / slower depending on the deviation from the desired set-point.
