Refractometer Brake Fluid (DOT 4)

Professional Handheld Refractometer, DOT4 Brake Fluid Hand refractometers are made with a variety of different scales to measure dissolved solids in solution. Hand refractometers are categorized according to the type of measurement scale required. All are easily transportable for field use, simple to use, and require only an outside light source to be functional. Models with the ATC designation are Automatic Temperature Compensated over a 30ºCtemperature range. Included in the set: • 1 x adjustment screwdriver • 1 x 5 ml pipette Brake Fluid Refractometers Brake Fluid Refractometers are precision optical testing instruments for measuring the boiling point and water content of DOT4 brake fluids. In seconds and with only two drops of brake fluid an accurate indication of the boiling point or percentage of water content can be obtained. Brake fluid may be measured from the master cylinder or from each of the wheel cylinders. Many automobile manufacturers recommend regular brake fluids inspections, but until now there was never an easy, inexpensive means for testing it. The Brake Fluid Refractometer represents the most accurate field testing means available for determining the boiling point and water content of brake fluids.
