This professional refractometer is a high-quality measuring device specifically developed for the quick and accurate quality control of critical fluids used in vehicles. It is an ideal choice for repair shops, workshops, and professionals who require reliable results, ranging from measuring the density of battery acid to the freezing point of coolant and the concentration of windshield washer fluid and AdBlue (SCR fluid).
The device operates on an optical principle, providing extremely simple operation and immediate, readable results, minimizing potential user error. Its wide applicability and robust design guarantee long-lasting, reliable performance even under the most intensive workshop conditions.
This refractometer is not just a simple measuring instrument; it is a versatile diagnostic tool that supports every aspect of vehicle maintenance and servicing where fluid quality needs to be checked.
Versatile Application: With a single device, it is capable of measuring four different types of fluids, thus reducing the number of required tools.
Könnyű Kezelhetőség: Only a few drops of the fluid to be tested are needed for the measurement. The results can be read quickly and visually on the scale.
Precise Measurement: A high-resolution optical system ensures precise results within the specified measurement ranges.
Automatic Temperature Compensation (ATC): The built-in ATC system automatically corrects measurement deviations caused by temperature fluctuations, ensuring consistent accuracy at ambient temperatures between 10°C and 30°C.
Robust Design: The housing, made of durable, high-quality materials, protects the internal optics against mechanical stress encountered in the workshop environment.
Convenient Focusing: An adjustable focus ring allows for achieving a clear image adjusted to the user's vision.
The refractometer scale contains multiple, independent measurement ranges, each serving to check specific fluids:
Battery Acid (Electrolyte): Checking the freezing point and electrolyte density, which is essential for assessing the battery's state of charge and winter protection.
Coolant (Antifreeze): Determination of the freezing point for ethylene glycol or propylene glycol-based antifreeze fluids, ensuring engine protection at low temperatures.
Windshield Washer Fluid: Checking the freezing point for alcohol-based summer and winter washer fluids.
AdBlue (SCR Fluid): Measurement of carbamide (urea) concentration (32.5% ± 0.7%), which is critical for the proper functioning of diesel particulate filter systems (SCR) and emission regulation.
The specifications of the device ensure compliance with the requirements for professional use:
| Parameter | Battery Acid | Coolant | Windshield Washer Fluid | AdBlue (Urea) |
|---|---|---|---|---|
| Measurement Range | 1.100 – 1.400 sg | -50°C – 0°C | -40°C – 0°C | 10% – 50% |
| Resolution | 0.01 sg | 5°C | 5°C | 5% |
| Pontosság | ± 0.01 sg | ± 5°C | ± 5°C | ± 5% |
| Temperature Compensation (ATC) | Yes (10°C – 30°C) | Yes (10°C – 30°C) | Yes (10°C – 30°C) | Yes (10°C – 30°C) |
| Sample Requirement | A few drops | A few drops | A few drops | A few drops |
| Optical System | High-quality prisms | High-quality prisms | High-quality prisms | High-quality prisms |
| Material | Metal housing with rubber coating | Metal housing with rubber coating | Metal housing with rubber coating | Metal housing with rubber coating |
The refractometer is delivered completely ready for work:
1 pc Refractometer (multifunctional)
Calibration screwdriver (for zero point adjustment)
Pipette (for sample collection)
Cleaning cloth
Robust storage box
The device is extremely simple to use, but for long-term accuracy, a few steps must be followed:
Sample Collection: Using the included pipette, apply 1-2 drops of the liquid to be tested onto the prism surface. Avoid air bubbles.
Readout: Point the refractometer towards a light source and look through the eyepiece. The sharp boundary visible on the scale indicates the measured value.
Cleaning: Immediately after every measurement, clean the prism with a soft, damp cloth or the included cloth, especially after measuring AdBlue, as urea can crystallize.
Calibration: Periodically, or when the accuracy of the measurement becomes questionable, calibrate the device with distilled water (it should show a freezing point of 0°C on the coolant/windshield washer fluid scale) or with the calibration fluid recommended by the manufacturer.
This refractometer is an essential tool for every modern vehicle service committed to fast, accurate, and reliable fluid diagnostics, especially considering the specific cooling and handling requirements of increasingly common electric and hybrid vehicles (e.g., fuel cell systems).
