This professional refractometer is a high-quality optical measuring device specifically designed for the quick, accurate, and reliable quality control of essential fluids used in vehicles. The device is the ideal choice for repair shops, workshops, and professionals who need to check the battery acid (electrolyte), the antifreeze content of the coolant, the freezing point of the windshield washer fluid, and the concentration of AdBlue (urea solution) daily.
The refractometer, featuring a multi-functional scale and built-in LED illumination, guarantees precise measurements even in poor lighting conditions, ensuring user-friendly operation and long-term reliability.
This refractometer is an indispensable tool for modern vehicle maintenance, offering several advantages to users:
Multifunctional Applicability: Testing four different fluids (battery acid, coolant, windshield washer fluid, AdBlue) with a single device reduces the number of required tools.
Excellent Optical Quality: The precisely designed optical system provides a clear, sharp image of the scale, minimizing reading errors.
Integrated LED Illumination: The built-in LED light source allows measurements to be taken even in dark garages or poorly lit areas, increasing flexibility.
Fast and Easy Handling: The measurement can be performed quickly and easily with just a few drops of fluid, ideal for busy workshop environments.
Automatic Temperature Compensation (ATC): The built-in ATC system automatically corrects potential measurement deviations resulting from temperature fluctuations, thus ensuring accurate results across a wide temperature range.
Robust Construction: The device is made from durable materials, resistant to workshop conditions.
The refractometer's specifications ensure broad usability and measurement accuracy.
| Parameter | Battery Acid (Electrolyte) | Coolant (Antifreeze) | Windshield Washer Fluid | AdBlue (Urea) |
|---|---|---|---|---|
| Measuring Scale | Specific Gravity (SG) | Freezing Point (°C) | Freezing Point (°C) | Urea Concentration (%) |

Optical System: High-resolution lenses for a clear field of view.
Material Usage: Metal housing (aluminum alloy or durable plastic) and rubber-coated eyepiece for comfortable use.
Calibration: Simple zero-point calibration with distilled water.
Sample requirement: Extremely low fluid requirement (approx. 2-3 drops).
The refractometer allows for a quick assessment of the battery's charge status by measuring the density (specific gravity) of the electrolyte.
Above 1.27 SG: Fully charged battery.
Around 1.20 SG: Partially charged state.
Below 1.10 SG: Discharged or faulty battery.
Accurate SG measurement is essential for assessing maintenance needs and checking warranty conditions.
In winter periods, knowing the freezing point of the coolant is critically important. The device checks whether the coolant contains sufficient antifreeze (usually based on ethylene or propylene glycol) concentration suitable for local climatic conditions. The scale directly shows the freezing point measured in degrees Celsius.
Checking the freezing point of summer and winter windshield washer fluids ensures the system does not freeze in cold weather. The scale quickly indicates the temperature up to which the fluid guarantees frost protection.
AdBlue (Diesel Exhaust Fluid, DEF) is a urea-based solution used in Selective Catalytic Reduction (SCR) systems that reduce harmful emissions from diesel engines. The quality and concentration of AdBlue (ideally 32.5% ± 0.7%) are extremely important for the efficient operation of the catalyst. The refractometer directly shows the percentage concentration of urea, thus helping to maintain optimal system operation and protect expensive components (e.g., SCR catalyst).
