Product Number: AK4123
Checking antifreeze concentration without a reliable tester can leave your cooling system unprotected against freezing. The Sealey AK4123 is a convenient, pocket-sized ball-type tester designed specifically for ethylene glycol antifreeze mixtures. Freeze protection level is indicated by the number of coloured balls which float in the sample, giving you a quick, easy-to-read result. An at-a-glance temperature table is printed directly on the body, so you can interpret your reading on the spot without needing to consult separate documentation. Compact enough to carry in a toolkit or pocket, it's a practical addition for any workshop or roadside check.
