HPM Launchpad is delighted to be running a competition with Fernox to offer 20 free Express Inhibitor Test kits, which make testing central heating systems for the correct concentration of inhibitor quicker and easier than ever.

WIN A FERNOX EXPRESS INHIBITOR TEST Simply dip the test strip into the system water and it will instantly change colour. By comparing the test strip to the colour chart label on the bottle, installers can assess whether the system water includes the correct concentration of inhibitor.

A fully protected system will have inhibitor levels of 100ppm or above – and will pass the test. However, if the test fails and a result of less than 100ppm is received, the system should be re-dosed.

To be in with a chance of being sent a free tub of test strips, simply email with your contact details.
