It gives a quick indication of inhibitor levels in the system water, helping ensure ongoing protection against rust, corrosion, and scale build-up.\u003c\/p\u003e\n\u003ch3 data-start=\"341\" data-end=\"365\"\u003eFunction \u0026amp; Purpose\u003c\/h3\u003e\n\u003cp data-start=\"366\" data-end=\"847\"\u003eThis test kit lets you assess the concentration of corrosion inhibitor in your central heating water on the spot. A small sample of system water is mixed with the test reagent supplied in the kit. A colour change then shows whether the inhibitor level is within the recommended range, too low (indicating topping up is needed), or absent. Maintaining correct inhibitor levels helps protect the boiler, radiators, pumps, and other components from corrosion and prolongs system life.\u003c\/p\u003e\n\u003ch3 data-start=\"849\" data-end=\"868\"\u003eCompatibility\u003c\/h3\u003e\n\u003cp data-start=\"869\" data-end=\"1153\"\u003eThe Express Inhibitor Test is suitable for use with \u003cstrong data-start=\"921\" data-end=\"983\"\u003emost domestic and light commercial central heating systems\u003c\/strong\u003e, including combi, system, and regular boilers. It checks the actual water drawn from the system, regardless of the brand of inhibitor used, making it broadly applicable.\u003c\/p\u003e\n\u003ch3 data-start=\"1155\" data-end=\"1183\"\u003eDesign \u0026amp; Build Quality\u003c\/h3\u003e\n\u003cp data-start=\"1184\" data-end=\"1507\"\u003eThe test kit is compact and designed for ease of use on site. It typically includes simple colour-matching reagents and a sampling tube or vial so that a sample of system water can be tested quickly and without specialist tools. The kit provides an immediate visual result, enabling fast assessment of inhibitor protection.\u003c\/p\u003e\n\u003ch3 data-start=\"1509\" data-end=\"1527\"\u003eKey Benefits\u003c\/h3\u003e\n\u003cp data-start=\"1528\" data-end=\"1879\"\u003eUsing this test kit helps ensure that corrosion inhibitor levels are adequate to protect the heating system against rust, oxidation, and scale formation. Regular testing can inform maintenance decisions, reduce the risk of premature component wear, help avoid breakdowns, and support better energy efficiency by keeping heat transfer surfaces cleaner.\u003c\/p\u003e\n\u003ch3 data-start=\"1881\" data-end=\"1905\"\u003eIdeal Applications\u003c\/h3\u003e\n\u003cp data-start=\"1906\" data-end=\"2269\"\u003eThe Fernox Express Inhibitor Test is ideal for \u003cstrong data-start=\"1953\" data-end=\"2011\"\u003eheating engineers, service technicians, and homeowners\u003c\/strong\u003e who want to verify that the central heating system is properly protected. It’s especially useful during servicing, after system cleaning, when adding new components, or as part of routine annual maintenance to confirm that inhibitor levels remain effective.\u003c\/p\u003e","brand":"Fernox","offers":[{"title":"Default Title","offer_id":57056154911065,"sku":"50010341","price":43.26,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0982\/9738\/1209\/files\/50010341_FO.jpg?v=1768817194","url":"https:\/\/plumbpartsxpressshop.com\/products\/fernox-express-inhibitor-test","provider":"Plumbparts xpress","version":"1.0","type":"link"}
