Product Data Sheet

Sentinel Instacheck is a water quality testing app designed to allow heating engineers quickly and effectively test heating system water quality.

InstaCheck tests for corrosion (through dissolved copper), pH levels and inhibitor through the InstaCheck Test Kits (sold separately).

Results and guidance are provided at each step of the process to allow engineers to quickly understand and remedy any issues with system water quality (including without an internet connection). After testing the app will create a PDF that can be sent to customers and chosen contacts that allows both engineers and customers to be informed of the system water health.
