The DTK comprehensive Closed System Test Kit for heating and chilled water systems has been developed specifically for engineers and treatment professionals responsible for the maintaining and management of closed water systems. This test kit has been designed to include the key parameters which enable the optimum operating conditions in these water systems.

The kit provides accuracy and speed, utilising drop test and comparator reagents together with electronic meters for the most efficient monitoring of water samples. The reagents and equipment are specified below.

The CLK003 is supplied in a robust carry case with reagents and instruments secured by a high quality chemical resistant foam insert with sufficient chemical reagents to carry out between 100 and 200 tests.


Closed Water Systems for Low Pressure Hot Water (LPHW), Chilled Water & Heating require regular and careful monitoring to ensure the correct water conditions are maintained within an approved treatment programme.

Any failure to maintain the correct levels and dosing of the chemical treatments can lead to;

  • Corrosion of the system (leaks),

  • Formation of scale (blocked pipes),

  • Increased biological activity.

These can lead to unstable water conditions with potential negative consequences to the life of the plant and operating costs.

This kit also comes with the Copper Free and Total Comparator as detailed below.
