This refractometer comes pre-programmed with all of the following scales:
Brake Fluid Refractometer – Brake Fluid Scales – Percent Water & Boiling Point °F – MISCO DOT3 Refractometer
Fahrenheit model – The MISCO Palm Abbe Brake Fluid Refractometer is a precision digital instrument designed for measuring the water content, and estimating the boiling point, of DOT3 brake fluids. It only takes two drops of brake fluid to get an accurate indication of water content or boiling point in only seconds. Brake fluid may be measured from the master cylinder or from each of the wheel cylinders.
