    Coolant is also called cutting fluid, is an industrial liquid used in metal cutting and grinding processes to cool and lubricate tools and workpieces. Coolant refractometer adopts high-definition prism, has atc temperature compensation and multi-range for selection. Refractometer can accurately measure the specific gravity of coolant and the freezing point of antifreeze. It is often used in management of cleaning fluid of metalworking parts and the configuration of coolant, antifreeze, quenching liquid, etc.

    Coolant/Antifreeze Refractometer Operation Instructions

    1. Calibrate the refractometer to 0.
    2. Place 2 to 3 drops of sample solution on the prism surface.
    3. Cover the prism cover, put it in a bright direction.
    4. Adjust knob until the internal scale is clear.
    5. Read the reading at the blue and white junction.

    Tips: Refractometer working principle.

    Refractometer is an optical instrument that works on the basis of total internal reflection. When light enter another transparent medium from a transparent medium, it causes refraction. The incidence angle of light when this phenomenon occurs is called critical angle. The phenomenon is due to the difference in speed at which light travels in a variety of different medium. Refractive index is the ratio of speed at which light travels through air to the speed at which it travels in other medium. The magnitude of critical angle is determined strictly by refractive index of the two species.
    Analysis of the liquid is based on analysis of solution concentration. Refractive index of the solution has a certain correspondence with its concentration, and solution concentration can be measured by conversion based on the correspondence. As the density of a substance increases, its refractive index increases accordingly. Refractometer is an instrument that uses the above principle to measure refractive index, birefringence, and light.
