Sealey VS0052 Antifreeze/Battery Fluid/Screenwash/AdBlue Refractometer

The Sealey VS0052 is a multi-purpose refractometer designed for accurately testing battery fluid, screenwash, antifreeze and AdBlue® strength in vehicle maintenance applications. This precision diagnostic tool measures the refractive index of light passing through fluid samples, providing reliable concentration readings essential for proper vehicle cooling system and fluid management. Built with a temperature-corrected prism, this refractometer ensures accurate measurements regardless of ambient conditions. The adjustable focus eyepiece allows for clear, easy reading of results, whilst the simple calibration process using distilled water maintains measurement precision over time. The instrument is suitable for modern synthetic antifreeze mixtures including long-life OAT (Organic Acid Technology) and G13 formulations, as well as measuring the aqueous/urea content of AdBlue®. This makes it ideal for workshops, garages and fleet maintenance operations working with contemporary vehicle flu
