ATC Car Auto Ethylene Glycol Antifreeze Refractometer Fluid Engine Coolant Test 

Product Descriptions:

 -  100% brand new and high-quality.
 -   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.

How to use:
1. Open the cover plate, use the cleaning cloth to clean the main prism.
2. Drop a few drops of the solution on the prism, lightly close the cover plate in case of bubbles appear. Let the solution cover the whole prism surface.
3. Aim the Refractometer to lights, take a look though the eyepiece and adjust the focus till you can see a clean vision of the boundary line of the Blue and White area.
4. Read the result where the boundary line sits.
