About This Item
Make automotive fluid testing more convenient with this 4-in-1 handheld refractometer. Designed for vehicle owners and automotive maintenance applications, this optical instrument measures antifreeze freezing points, windshield washer fluid freezing points, lead-acid battery electrolyte specific gravity, and diesel exhaust fluid concentration. Its compact design, glass prism, and adjustable eyepiece provide a practical solution for regular fluid checks.

What Problem It Solves
Different automotive fluids require different measurement scales, making routine vehicle inspections inconvenient when multiple tools are needed. This multifunction refractometer combines four fluid-testing applications in one handheld instrument, helping simplify maintenance checks and reduce the need for separate optical testers.

How It Works
Open the daylight plate and place a small sample of the appropriate automotive fluid onto the clean glass prism using the included pipette. Close the plate to spread the sample evenly, then point the refractometer toward a suitable light source. Look through the eyepiece, adjust the focus, and read the boundary line against the corresponding measurement scale. Clean the prism after each test.

Key Features
- 4-in-1 Measurement Scales: Supports antifreeze, battery electrolyte, windshield washer fluid, and DEF testing.
- Automatic Temperature Compensation: Helps account for temperature-related changes during measurement.
- Glass Optical Prism: Provides a clear surface for examining fluid samples.
- Adjustable Eyepiece: Allows convenient focusing of measurement markings.
- Textured Non-Slip Grip: Supports comfortable handheld operation.
- Calibration Adjustment Screw: Allows calibration according to the operating instructions.
- Battery-Free Operation: Uses ambient light for optical measurements.

Why Choose This Product
This automotive refractometer combines multiple fluid measurement functions with straightforward optical operation. Its glass prism, adjustable eyepiece, ATC feature, and included accessories provide a practical testing solution for vehicle maintenance. The battery-free design also eliminates the need for charging or replacing batteries.

Perfect For
Home garages, automotive workshops, routine vehicle inspections, coolant mixture checks, windshield washer fluid testing, compatible lead-acid battery maintenance, and diesel exhaust fluid concentration checks.

Make Vehicle Maintenance More Convenient
Add this 4-in-1 automotive refractometer to your garage tools and simplify routine fluid measurements with one compact, easy-to-use optical instrument.
