Field of View Description:
Intermediate scale: (ETHYLENE GLYCOL) Ethylene glycol antifreeze freezing point.
         (PROPYLENE GLYCOL) Propylene glycol type antifreeze freezing point.
Left scale: (BATTERY FLUID) Battery liquid specific gravity.
           1.15 ~ 1.20 to be charged
          1.20 ~ 1.25 power enough
          1.25 ~ 1.30 sufficient power
Right scale: glass cleaning solution freezing point
First, the principle:
The instrument can measure the antifreeze and glass cleaning agent freezing point, the proportion of lead-acid battery electrolyte. Temperature compensation device is included to ensure the measurement is simple and convenient, to ensure accurate measurement in the 10oC ~ 30oC ambient temperature.
 
The basic principle is to use the total reflection critical angle method to measure the refractive index of the solution, and then calibrate the measured liquid concentration and its performance. Because of its principle of reliable, accurate to meet the actual needs, there are small size, light weight, handsome in appearance, easy to use, it is widely used in the automotive industry.
 

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.
* Allows easy steps for quick and accurate testing/analyzing the glycol concentration of engine coolants or other anti-freeze solutions.
* Equipped with ATC (Automatic Temperature Compensation), can automatically adjust itself to correct temperature discrepancies while being used.
* 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.
