The Sentinel Quick Test Kit (MPN X100T-QT-GB) is a simple, disposable, colour-comparison test for confirming that Sentinel X100 Inhibitor has been dosed at the correct concentration within a sealed central heating system. Once a system has been cleaned and protected with X100, this kit gives installers and service engineers an on-site check within minutes, providing reassurance that the customer's system is properly protected against the two leading causes of central heating inefficiency: limescale and corrosion.

Test Method
Servicing & Commissioning
Use Case
Routine Servicing Tool
Designed for routine servicing, commissioning checks and maintenance visits where a quick confirmation of X100 inhibitor concentration is needed rather than a full multi-parameter water analysis.
Product Specific
This kit is formulated specifically to test for Sentinel X100 Inhibitor concentration. It is not a general water quality or multi-parameter test - for broader analysis of inhibitor, corrosion, pH and turbidity together, a digital test kit such as ADEY ProCheck should be used instead.
Fast Dosage Confirmation
Gives a quick, disposable check that Sentinel X100 Inhibitor is present in the system at a sufficient concentration to provide ongoing protection.
Simple Colour-Match Process
Uses a test tube, tablets, and colour comparison chart - no smartphone or app required, making it a low-cost option for a rapid on-site check.
Ideal for Aftercare Visits
Well suited to routine service and maintenance visits, giving engineers a documented reason to reassure customers their system remains protected.
Ready for Repairs
Useful during emergency repairs or quick fixes where confirming existing inhibitor levels quickly helps decide whether a top-up dose is required.
Compact and Portable
Small, lightweight kit that fits easily in a van or tool bag alongside other water treatment testing equipment.
Two-Test Capacity
Supplied with enough tablets and materials for two separate on-site tests, covering two visits or a retest where needed.

What does the Sentinel Quick Test Kit actually check?
It checks that a central heating system treated with Sentinel X100 Inhibitor has been dosed to a sufficient concentration for proper ongoing protection against limescale and corrosion.
How many tests are in one kit?
Each kit contains enough tablets and materials to carry out two separate tests (1 test tube, 2 No.1 tablets, 2 No.2 tablets, and a colour comparison chart).
Can this test other Sentinel or third-party chemicals?
This kit is formulated specifically for Sentinel X100 Inhibitor. It is not designed as a general multi-brand or multi-parameter water quality test.
When should I use this instead of a digital test kit?
It's ideal for a quick, low-cost concentration check during routine servicing or a repair visit. For a fuller picture including corrosion, pH and turbidity, a digital kit such as ADEY ProCheck may be more appropriate.
Is any equipment needed to read the results?
No. Results are read using the supplied colour comparison chart - no smartphone, app, or additional equipment is required.
