## Technical Data and Measuring Ranges<\/p>\n
The refractometer offers specific measurement scales for the following fluid types and parameters:<\/p>\n
| Fluid Type | Measured Parameter | Measuring Range | Resolution |
\n| :— | :— | :— | :— |
\n| **Battery Acid (Electrolyte)** | Specific Gravity \/ Freezing Point | 1.10 \u2013 1.40 sg | 0.01 sg |
\n| **Coolant (Antifreeze)** | Ethylene Glycol \/ Propylene Glycol | -40 \u00b0C \u2013 0 \u00b0C | 10 \u00b0C |
\n| **Windshield Washer Fluid** | Methanol \/ Ethanol Content | -40 \u00b0C \u2013 0 \u00b0C | 10 \u00b0C |
\n| **AdBlue (SCR Fluid)** | Urea Concentration | 10% \u2013 50% | 5% |<\/p>\n
### Further Technical Specifications<\/p>\n
* **Housing Material:** Solid aluminum
\n* **Optical System:** Precision lenses
\n* **Focusing:** Adjustable focus ring
\n* **Temperature Compensation:** Automatic temperature compensation (ATC) for accurate measurements across a wide temperature range.
\n* **Calibration:** Factory pre-calibrated, easily recalibrated with distilled water if necessary.<\/p>\n
## Detailed Application Areas<\/p>\n
### 1. Battery Acid Check<\/p>\n
The refractometer allows you to check the charge status of lead-acid battery electrolytes by measuring the specific gravity (sg). The correct specific gravity directly correlates with the battery's charge level, helping to identify maintenance needs before performance degradation occurs.<\/p>\n
### 2. Determining Coolant Freezing Point<\/p>\n
Modern vehicle cooling systems use complex mixtures (based on ethylene glycol or propylene glycol). This device accurately indicates the freezing point, ensuring the coolant provides adequate protection against damage to the engine and cooling system during winter. The scale for both types of glycol (Ethylene and Propylene Glycol) allows for the measurement of different types of antifreeze fluids.<\/p>\n
### 3. Windshield Washer Fluid Effectiveness<\/p>\n
During the winter season, proper freeze protection for windshield washer fluid is essential. The refractometer quickly determines the methanol or ethanol content, thus guaranteeing that the fluid will not freeze in the nozzles or the tank.<\/p>\n
### 4. AdBlue (DEF) Concentration Measurement<\/p>\n
AdBlue (Diesel Exhaust Fluid, urea solution according to ISO 22241 standard) is essential for reducing harmful emissions from diesel vehicles (SCR technology). Too low a concentration (dilution with water) can cause system malfunction and limit vehicle performance. This refractometer is capable of measuring urea concentrations between 10% and 50%, ensuring AdBlue quality compliance.<\/p>\n
## Operating Instructions Summary<\/p>\n
1. **Cleaning:** Wipe the measuring prism and the inside of the cover clean with a soft, clean cloth.
\n2. **Sampling:** Lift the cover plate and place 1-2 drops of the fluid to be tested onto the prism.
\n3. **Closing:** Carefully close the cover plate so that the fluid spreads evenly over the prism surface without air bubbles.
\n4. **Measurement:** Hold the refractometer in a bright place and look through the eyepiece. The sharp dividing line visible on the scale indicates the property of the fluid on the selected scale.
\n5. **Temperature:** Automatic Temperature Compensation (ATC) ensures that the ambient temperature does not significantly affect the reading (typically between 10\u00b0C and 30\u00b0C).<\/p>\n
