4-in-1 Tester - Measuring Freezing of automoblie antifreeze based on ethylene glycol or propylene glycol -60℉ to 32℉. Measuring Specific Gravity of battery acid 1.10 to 1.40Kg/L. Measuring of Windshield Washer Fluid based on ethanol or isopropyl alcohol -40℉ to 32℉. Measuring Urea Concentration in automobile diesel exhauset fluid (DEF) 30% to 35%.
Display In Fahrenheit - Updated antifreeze coolant refractometer in Fahrenheit (℉) display, allow you easy to read measured results by ℉ unit, no need to units conversion and save your time.
ATC Function - Coolant refractometer Fahrenheit can automatically compensate temperature when ambient temperature changes, eliminate the deviation, you can get the accurate results fast and easier.
Easy To Use - Only need 2 or 3 drops of solution and wait for few seconds, then you get the accurate results. These antifreeze tester needs less sample solution than tradistional hydrometer and less expensive then digital refractometer.
Durable And Portable - Antifreeze coolant tester is made of aluminum and ABS rubber, non-staining, anti-rust and stury for long perfermance. Comes with durable plastic box, portable and easy to take with you.

Convenient, pre-mixed coolant for motorcycles, ATVs, karts, etc.-pour and go.
Blended with purified, deionized water and proper WaterWetter percentage.
Reduces rust, corrosion and electrolysis, cleans and lubricates water pump seals.
Compatible with all antifreeze and coolant.
Satisfies ASTM D2570 and ASTM D1384 corrosion tests for glycol-based antifreezes.

Coolant Filling Kit: 5 direct fit radiator adapters, 4 caps, 2 45 degree elbows, 1 5 inch straight extension, 1 fluid stopper, 1 fluid tester, and 1 clear funnel.
Easy to Use: This spill free funnel kit makes coolant filling simple.
Select the correct adapter, attach the funnel, and fill.
Adapters fit most passenger vehicles and light trucks.
Don’t Get Stuck: The 45 degree angled elbows as well as the 5 inch straight extension in the coolant funnel kit allow you to access hard to reach areas.
Mess Free Coolant Refill: The fluid stopper prevents drips and spills when removing the funnel from the filler neck.
The adapter gaskets also prevent fluid leakage.
Test the Waters: The included coolant tester in this spill proof coolant filling kit quickly provides the freezing point of glycol-based coolants.

Robinair's Coolant and Battery Refractometer is designed for use in measuring the freeze point of propylene or ethylene glycol based cooling systems and for checking the strength of electrolyte solution batteries.
Precision instrument features high-quality optics with ultra smooth focusing to ensure reliable, accurate test results.
When a liquid (such as coolant or charging liquid) is placed on the tools prism, the light passing through it is bent - the more concentrated the liquid, the more the light will bend.
Scale range: -60 degrees Fahrenheit to +32 Fahrenheit.
Complete kit includes refractometer with rugged aluminum housing, eyedropper, screwdriver, vial of distilled water, cleaning cloth, foam lined rigid plastic case, and more.

Antifreeze Refractometer for car. Designed for measuring coolant and antifreeze based on ethylene glycol or propylene glycol.
Requires only a few drops of sample Measurement in 2 seconds.
Power off: Meter will power off within one minute if no any operation.
With temperature display, freely switch operating. Automatic Temperature Compensation is an absolute necessity for refractometer.
Portable and Exquisite, Low power consumption, Anti-loss design.
