High Pressure pH Probe from Ken Kimble (Reactor Vessels) Ltd

For Measurements Under Pressure

High Pressure pH Probe with Adapters

The measuring accuracy of the pH sensor is in the 5% range. However the exact calibration of the sensor is much more important. Calibration with a buffer solution is essential prior to conducting experiments involving the determination of the exact pH value.

Pressure Resistance

The pressure inside the pH sensor must be the same as the ambient pressure to enable pH measurements at high pressure. the new pH sensor has been equipped with a pressure equalisation opening.

The sensor itself is not subject to wear. Only the electrolyte needs to be refilled from time to time.

How Are Measurements Made?

When the pH measurement is being made, the potential of the measuring electrode is compared with that of the reference electrode.

Both electrodes are installed in a single combination electrode. The tip of the glass sensor is designed with a diaphragm so that H or OH ions change the electrical conductivity of the electrolyte by a diffusion process. The pH value can be derived from the change in potential between the measuring and reference electrodes.

Installation

The protection tube is available in standard lengths of 180 and 210 mm. Shorter protection tubes and other materials such as Hastelloy can be supplied on request.
