Product Description
From the manufacturer
The main function of this refractometer is to detect various antifreeze conditions.
Before the arrival of winter, the owner must remember to check the various liquids in the car. Qualified liquids in automobiles are essential for car safety to survive the cold winter.
If you have this refractometer, it can help you directly check the condition of the coolant, window cleaning fluid, Adblue, and battery fluid to determine if you need to replace these fluids to ensure safe driving, which will save you the cost of going to the automobile repair service.
You can also use this refractometer to configure a variety of liquids without buying the same high quality branded products.
The Refractometer is equipped with two scales for measuring of windscreen washer fluids, two scales for measuring of engine coolants , scale for measuring of battery electrolyte condition and scale for measuring of liquid additive AdBlue. The scales for windscreen washer fluids are under the „wipers icon“ – the scale on the left is designed for Ethanol + water mixture, the scale on the right (signed as SRF1) is designed for mixture Isopropanol + water.
The models have only one unit system: ℉. With the indication of the percentage we may know the freezing point of either ethylene glycol or propylene glycol based cooling systems. You can use it to check the temperature (freezing point ) of the condensation of your cooling water.
This product has been improved to a higher level of accuracy. The measured data is close to the ASHRAE standard. The new product adds functionality and can be used to measure AdBlue.
The unit can be used to check the proportion of battery fluid, instead of the use of hydrometer. Safe and reliable.
This product is used to measure the freezing temperature limit of automotive coolant. It is used as a tool to protect the car engine.
The instrument is resistant to abrasion and corrosion resistance. Can be measured acidic and alkaline and other general corrosive liquid.
Compensation temperature range: 50℉- 86℉
Calibration: Zero calibration with water close to 68 ℉.
Function 1: Measuring freezing point of automobile antifreeze based on ethylene glycol or propylene glycol(G11, G12, G13). Measuring Range: -60°F-32°F.
Function 2: Measuring specific gravity of battery acid and provide a quick reference of battery charge condition. Measuring Range:1.10 to 1.40 kg/l
Function 3: Measuring windshield washer fluid based on ethanol or isopropyl alcohol. Measuring Range: 32°F to -40°F
Function 4:Measuring Urea Concentration in automobile diesel exhaust fluid (DEF). Measuring Range:30% to 35%
Warning-Maintenance:
1.Calibration liquids can use clean water. This product does not require frequent calibration. The temperature of the liquid to be measured should be close to the temperature of the prism to measure the data is accurate.
2.The instrument is resistant to abrasion and corrosion resistance.Can be measured acidic and alkaline and other general corrosive liquid. But we do not recommend measuring these fluids for a long time. The residue should be cleaned immediately after measurement.
3.This is an optical instrument. Do not need regular maintenance. But you have to be careful, the vast majority of damage is due to fall, which will cause the instrument difficult to repair.
Package included:
1 x Refractometer
4 x Plastic Pipette

Homemade Antifreeze Fluids
To make sure that your vehicle has the proper amount of antifreeze at all times.
Having a low amount of antifreeze can cause your engine to overheat or freeze up, so make sure to check these levels every 2 to 3 months.
DIY-You can use this refractometer to formulate antifreeze.
Save a lot your money and drive safely.
Homemade Windshield Washer Fluids
Method 1:
2 cups isopropyl alcohol, 1 cup white vinegar, 3 quarts water, 2 Tbsp liquid dish soap, 5 drops blue food coloring (optional)
Method 2:
Ethanol+ water.
To Measure the Specific Gravity of the Battery Fluids
The lead-acid batteries require regular maintenance to function properly. We recommend checks every 2-4 weeks to keep the battery bank tuned up.
With this refractometer you only need to take a few drops of battery fluid.
Homemade AdBlue /Diesel Exhaust Fluids (DEF)
Diesel Exhaust Fluid (DEF) is a non-hazardous solution, which is 32.5% urea and 67.5% de-ionized water. DEF is sprayed into the exhaust stream of diesel vehicles to break down dangerous NOx emissions into harmless nitrogen and water.
