4-in-1 antifreeze refractometer ethylene glycol, propylene glycol, for automotive cooling fluid, Windshield washer fluid, AdBlue(DEF), automotive and industrial battery fluid measurement

Features: The refractometer is designed according to the principle of different concentration of liquid having different refractive index. Specially designed to apply for automatic cars/vehicles battery antifreeze fluids glycol testing and analyzing. Equipped with ATC (Automatic Temperature Compensation), can automatically adjust itself to correct temperature discrepancies while being used. Allows easy steps for quick and accurate testing/analyzing the glycol concentration of engine coolants or other anti-freeze solutions. You may easily know the freezing point for both propylene glycol and ethylene glycol, with the indication of the percentage. It is also used for checking the strength of electrolyte solution batteries. Decorated with soft and comfortable anti-slip rubber. Small size and light weight, makes it a portable one, very convenient. The best partner for the car-owners in winter. Measuring Range: Propylene Glycol:-50 to 0°C Ethylene Glycol:-50 to 0°C Cleaning Fluids:-40 to 0°C Battery Fluids:1.10-1.40sg Resolution Factor: Propylene Glycol:5°C Ethylene Glycol:5°C Cleaning Fluids:5°C Battery Fluids:0.01sg Package content : 1 x Antifreeze Fluids Refractometer 1 x Mini-screw Driver 1 x Pipette 1 x Cleaning Cloth 1 x Carrying Case

• 🚗【4-in-1】— If you notice that the battery of your your cars, solar plant or heat pumps is not durable anymore, DO NOT hurry to change it. This antifreeze refractometer will help to measure the specific gravity of your battery acid, then provide a quick reference of battery fluid condition. Also the refractometer can be used to measure cleaning fluids freezing point, screenwash antifreeze point, ADBlue point.
• 🚗【Easy to Use】—Place 2 - 3 drops of sample onto the prism of the refractometer, then look through the eyepiece to get the reading directly.
• 🚗【ATC Design】—The refractometer adopt Automatic Temperature Compensation from 10℃ to 30℃ (50°F~86°F), reading directly, fast, accurate and light weight.
• 🚗【MEASURING RANGE】—Ethanediol (ethylene glycol): 0 to -50 ° C; Propanediol (propylene glycol): 0 to -50 ° C; windshield cleaning liquid - ethanol + water: 0 ° C to -40 ° C, sopropyl alcohol + water (SRF1): 0 ° C to -40 ° C. AdBlue: urea concentration 30% - 35%, Battery acid from 1.10 to 1.40 kg / L
• 🚗【Packing List】— 1 x refractometer; 1x calibration screwdriver; 1 x pipette; 1 x instruction manual; 1 x cleaning cloth, and a free hard case included which make the refractometer convenient to store and carry around.
