This professional refractometer is an indispensable tool for every modern workshop that requires precise and fast quality control for critical vehicle fluids. The device is ideally suited for measuring the battery acid electrolyte, the freezing point of coolants, the freezing point of windshield washer fluids, and the concentration of AdBlue (Diesel Exhaust Fluid - DEF).
The refractometer operates on an optical principle, is extremely reliable and easy to handle, ensuring quick and accurate results even under the most diverse temperature conditions.
This versatile measuring instrument significantly simplifies maintenance and service tasks, as the parameters of several important fluids can be checked with a single device:
Multifunctional Application: The freezing point of coolant (ethylene- or propylene glycol-based), the specific gravity of battery acid (electrolyte concentration), the freezing point of windscreen washer fluid, and the concentration of AdBlue (DEF) can be measured with a single device.
Könnyű Kezelhetőség: Simple sampling and quick reading. Only a few drops of the fluid to be tested are needed for an accurate measurement.
Automatic Temperature Compensation (ATC): The built-in ATC system automatically corrects for temperature fluctuations, thus guaranteeing accurate results over a wide temperature range.
Excellent Optical Quality: Bright, clear field of view for easy and error-free reading.
Robust Construction: Made from durable materials, resistant to the rigors of the workshop environment.
The precise measurement capabilities of the refractometer are supported by the following specifications:
| Parameter | Coolant (Ethylene/Propylene Glycol) | Windshield Washer Fluid | Battery Acid (Electrolyte) | AdBlue (DEF) |

| Resolution | 1 °C | 5 °C | 0.01 g/ml | 1% |
| Pontosság | ± 1 °C | ± 5 °C | ± 0.01 g/ml | ± 1% |
| Temperature Compensation | Automatic (ATC) | Automatic (ATC) | Automatic (ATC) | Automatic (ATC) |
| Sample Requirement | Minimum Quantity | Minimum Quantity | Minimum Quantity | Minimum Quantity |
1. Coolant Testing:
Checking the freezing point of the coolant is essential for maintaining engine life and efficiency. This refractometer is capable of distinguishing between ethylene glycol (longer life, general) and propylene glycol (more environmentally friendly) based antifreeze, and accurately shows the protection level on the given temperature scale. Early detection prevents damage caused by freezing, such as cracking the cylinder head or the cooling system.
2. Battery Acid (Electrolyte) Specific Gravity Measurement:
Assessing the charge status of the battery is crucial. The refractometer measures the specific gravity (density) of the electrolyte, which directly correlates with the battery's charge level. Values below 1.10 g/ml indicate a low charge, which can lead to acid stratification and capacity loss.
3. Windscreen Washer Fluid Check:
Especially in winter periods, knowing the freezing point of the windshield washer fluid is critical. The device quickly determines whether the fluid provides sufficient protection against the expected external temperatures, avoiding pump or tank damage caused by freezing.
4. AdBlue (DEF) Concentration Measurement:
The quality of AdBlue (urea solution used in SCR systems) directly affects the emissions and the operation of the SCR system in diesel vehicles. A urea concentration around 32.5% ensures adequate reduction of NOx emissions. The refractometer allows checking if the refilled AdBlue meets standards and has not been diluted or contaminated.
The kit designed for professional use generally includes the following, ensuring long-term, trouble-free operation:
Refractometer Main Unit: The calibrated optical measuring instrument.
Calibration Screwdriver: For setting the zero point of the device (usually for calibration with distilled water).
Pipette/Dropper: For precise sample collection.
Carrying Case: For protecting the device during transport and storage.
Operating Instructions: The precise operation and maintenance instructions.
This refractometer is the ideal choice for automotive workshops, fleet managers, technical inspection stations, and service centers, where quick and reliable checking of fluid quality is essential for professional work.
