The ADEY ProCheck App has been designed to work with the ADEY ProCheck Test Kit (sold separately) to provide heating engineers with a quick and easy method of testing central heating system water quality in the home using a smart phone. ADEY ProCheck's step by step process provides instant validation of system health, testing for the main parameters affecting system water quality. It gives instant results for Inhibitor, Corrosion and pH levels. Results are displayed within the app, offering recommendations for corrective action where required. ADEY ProCheck results can be shared instantly via the app to a known email address as a PDF document (subject to subscription) or via the ADEY ProCheck central management portal, where results can be retrospectively reviewed and compared over time (subject to subscription).
