A refractometer is a device that determines the physical properties of a liquid by measuring the refractive index at the boundary of the medium.

This allows you to specify:
– battery charge level
– Freezing point of propylene glycol or ethyl alcohol based fluids
– Freezing point of the washer fluid.

Professional refractometer for measuring the operating fluids of cars, trucks and buses. It is designed to determine the frosting temperature of the washer fluid, propylene glycol cooling and ethyl glycol. It also gives an electrolyte density range.

The kit includes a sampling pipette and a cleaning cloth. All packed in a solid plastic box.
How to use
Fluid measurement:
– Pick up a small amount of liquid with the pipette.
– Raise the dispersion plate and apply 2-3 drops of liquid to the prism of the instrument.
Lower the dispersion plate to distribute the liquid to be evenly distributed on the surf
