4 in 1 Car Refractometer for Antifreeze, Battery Fluid, Urea and Coolant Testing

Check key vehicle fluids quickly with one handheld car refractometer. It measures antifreeze, battery fluid, glass cleaning solution, and vehicle urea concentration with automatic temperature compensation for reliable spot checks.

4 in 1 fluid testing for faster vehicle maintenance

✅ Save time by checking four automotive fluids with one tool.

✅ Avoid winter fluid issues by verifying freezing point before temperatures drop.

✅ Read battery fluid condition clearly with specific gravity measurement.

✅ Confirm urea concentration accurately with a 30–35% measurement range.

✅ Get more consistent readings in normal working conditions with automatic temperature compensation from 10C to 30C.

✅ Carry and use it easily thanks to the compact 15.6 × 4 cm handheld design.

The glass prism construction supports concentration testing across common workshop checks. Use it for antifreeze testing, battery electrolyte checks, glass water freezing point testing, and vehicle urea concentration testing.

Measurement ranges include antifreeze from -50C to 0C, glass water from -40C to 0C, ethylene glycol 0–70%, propylene glycol 0–70%, and battery fluid specific gravity from 1.10 to 1.40 kg/L. Resolution is 5C and 5%, with urea concentration resolution at 0.2%.

Please note: urea test solution is not included. This tool can be ordered with or without a box.
