Refractometer electrolyte fluid tester amio

Refractometer coolant and electrolyte tester Essential in every workshop, the refractometer is a device that allows determining the physical properties of liquids by measuring the refractive index at the interface of media. Professional refractometer for measuring operating fluids of passenger cars, trucks, and buses. Designed to determine the freezing point of windshield washer fluid, propylene glycol coolant, and ethylene glycol. Also provides electrolyte density range. The set includes a pipette for sample collection and a cleaning cloth. All packed in a handy box. Set contents: Three-scale refractometer Sturdy comfortable foam-lined case Pipette for collecting and applying liquid to the prism Microfiber cloth for cleaning the prism and lens Calibration screwdriver Tester determines battery charge level, freezing temperature of fluids based on propylene glycol or ethyl alcohol, freezing temperature of windshield washer fluid.
