pH and Redox

With increasing legislation and environmental demands, accurate measurement and control of wastewater parameters is essential for the treatment of effluents to reduce the impact of industry on the environment.

The simplest and most useful of these is pH, the measurement of acidity and alkalinity of a solution. pH is one of the most common analytical measurements used in process control as many chemical reactions rely on the pH of a process being maintained at the correct value. By using accurate pH measurement it is possible to automate and improve the efficiency of a process minimising waste and reducing costs.

Redox measurement is used in cooling tower, swimming pool and industrial applications to control the addition of reagents and treat toxic chemicals in industries including metal finishing, biotechnology, municipal and industrial waste water.

COVID-19: Staying safe whilst we remain open


On 16 March 2020 we implemented a number of measures to protect the wellbeing of our staff and to mitigate any supply issues to our customers. From a Calibration Laboratory service perspective, we have split our staff into two shifts to reduce contact within the business whilst maintaining laboratory continuity.
Our Sales, Accounts and Admin staff are all working from home for the foreseeable future.
We can assure you that we will continue to do all we can to protect our staff, customers and their families.

You can contact us by phone 045 896660, or by email info@classictechnology.ie Our business hours are Monday to Friday 8.30am-5pm
