portable brake fluid refractometer

A portable brake fluid refractometer is a tool used to measure the refractive index of brake fluid. A small sample of the brake fluid is taken using a pipette or a similar tool. The sample is applied to the glass surface of the refractometer.When light passes through the sample, the refractometer measures the bending of the light, which is influenced by the refractive index of the fluid. The refractive index is typically correlated with the water content in the brake fluid. Higher water content can negatively impact the performance of the brake system.DOT 3 measuring range-121 °C ~ 260 °C;DOT 4 measuring range-125 °C ~ 275 °C;Refractive index-1.3330 nD ~ 1.5177 nD for more visit labtron.us
