X100Check

Inhibitor test strips for central heating systems
Ensure your heating system stays protected with X100Check Inhibitor Strips — the fast, easy-to-use test strips that reveal inhibitor concentration. Designed for domestic systems, they help you verify inhibitor levels, helping to prevent corrosion and prolonging boiler life. No lab, no guesswork — just quick, reliable results.

50 tests
Sentinel X100Check contains 50 test strips

Simple testing process
Each test strip is simple to use and provides fast results with no need for laboratory testing

Install and servicing testing
Ideal to test for inhibitor levels at both install and servicing

Helps to protect boilers
Identifies whether inhibitor needs adding in order to prevent corrosion

Description
Based on best practice, the X100Check test strips allows engineers to test and therefore adjust inhibitor levels within the system. A quick and easy way to ensure the correct levels of system inhibitor are present after installation or for servicing.

Usage
1 pot of X100Check provides 50 tests for inhibitor levels. This provides 3 potential results.
Low inhibitor present – add inhibitor. Inhibitor is at the correct level – no inhibitor to be added. Inhibitor levels are too high – circulate the system water to achieve better mixing of inhibitor.
Correctly dosed inhibitor ensures the system is adequately protected against the effects of corrosion and limescale.
