Car maintenance, automotive servicing, and fluid quality control.
Whatever your application, you can find the right refractometer to ensure accurate and reliable fluid measurement.
Measuable Liquids
Our automotive antifreeze and coolant refractometers are commonly used to measure:
- Coolant / Antifreeze – Quickly determine the freezing point of ethylene or propylene glycol-based coolant to ensure proper engine protection.
- Battery Fluid – Measure the specific gravity (SG) of battery electrolyte to assess battery health and performance.
- DEF / AdBlue – Check the urea concentration to ensure compliance with emission standards.
- Windshield Washer Fluid – Measure both the concentration and freezing point to guarantee visibility in cold weather conditions.
