Antifreezing & Coolant & Brake Fluid Refractometer

1pc/plastic box , 20plastic box/carton, G.W. 7kgs/carton

These model can be used for measuring the freezing point.

They can you whether the antifreeze contains the right amount of either ethylene glycol or propylene glycol antifreeze solution,

it can also be used for checking the strength of electrolyte solution batteries, and testing the cleaner water too.
