The ROOKS automotive refractometer is designed for fast, accurate assessment of battery electrolyte and vehicle operating fluids. It enables service technicians to check fluid condition directly and make informed maintenance decisions.
Only a small fluid sample is required, reducing waste and making the instrument quick and convenient to use. The optical scale provides immediate results without an external power source.
Suitable for automotive workshops, service centres, vehicle fleets and private garages when checking batteries, coolant and washer fluids.
