Refractometer for Battery Acid, Coolant, Windshield Washer Fluid, and AdBlue Testing
This professional refractometer is an indispensable tool for every modern workshop requiring precise and fast quality control of critical vehicle fluids. The device is perfectly suited for determining the concentration and condition of battery acid (electrolyte), coolants (antifreeze and corrosion inhibitor additives), windshield washer fluids (alcohol content), and AdBlue (urea solution).
Using the refractometer is extremely simple, provides fast results, and guarantees that vehicles always use fluids with optimal composition, ensuring long service life and safe operation.
Key Features and Advantages
This versatile measuring instrument provides the highest level of accuracy in checking the composition of various fluids:
- Multifunctional Application: With a single device, it can measure the condition of antifreeze (ethylene- or propylene glycol-based), battery acid (density), windshield washer fluid (methanol/ethanol content), and AdBlue (urea concentration).
- Könnyű Kezelhetőség: The ergonomic design and simple operation of the device minimize measurement time. Only a few drops of sample are needed for an accurate result.
- High Accuracy: The precisely calibrated optical system guarantees reliable and repeatable measurement results.
- Durability: Thanks to its robust design, it is ideal for withstanding the rigors of the workshop environment.
- Easy Reading: The large, easily visible scale makes quick evaluation of measurements easier.

Application Areas Details
1. Cooling System Maintenance (Antifreeze)
Maintaining the optimal temperature of the motor is crucial. The freezing point of the coolant can be checked with the help of the refractometer.
- Ethylene glycol-based antifreeze: Precise measurement for winter protection.
- Propylene glycol-based antifreeze: Safe inspection in systems used in areas sensitive to food industry or environmental concerns.
Incorrect concentration not only increases the risk of freezing but also reduces the efficiency of corrosion protection additives, which damages the engine components in the long run.
2. Battery Acid Test
The charge status of the battery is quickly assessed by measuring the acid density.
- A value around 1.27 g/cm³ indicates a fully charged state.
- A value below 1.15 g/cm³ indicates deep discharge, requiring immediate charging.
This function is essential for assessing the condition of traditional lead-acid batteries.
3. Windshield Washer Fluid Quality
The appropriate alcohol content of the windshield washer fluid is critical during the winter period.
- The device distinguishes the freezing points of methanol and ethanol-based fluids, ensuring the washer fluid does not freeze in pipes or on the windshield.
4. AdBlue (SCR Systems) Inspection
AdBlue (or DEF – Diesel Exhaust Fluid) is a urea-based solution essential for reducing harmful emissions from modern diesel engines (Selective Catalytic Reduction – SCR).
- Critical Concentration: AdBlue efficiency depends on a 32.5% carbamide concentration. The refractometer accurately measures this ratio.
- Faulty AdBlue: If the concentration is too low (e.g., due to water addition), the SCR system will not function properly, leading to error codes and potential limitation of engine performance. This function helps prevent costly repairs.
