The equipment will continuously control pH value with an accuracy of ± 0·05 unit for periods of many hundred hours. The pH value may be changed at will by turning a knob on the controller. It is sufficient to check the pH meter standardization once every day or two. The main components of the apparatus are standard commercial products.
