The Sealey VS027 is a professional brake fluid tester designed for quick and accurate assessment of brake fluid moisture content in automotive workshops and garages. This comparative electrolytic type tester works by measuring the resistance of brake fluid to electric current, providing an immediate indication of fluid condition and whether replacement is needed. The unit features an intuitive three LED read-out system combined with an audible test cycle, making it simple to interpret results during brake service work. Operation is straightforward – just insert the probe into the brake fluid reservoir and press the button for an instant reading. The tester can be easily calibrated using fresh brake fluid to ensure continued accuracy over time.
