Description
The Automotive Refractometer Tests Coolant, Battery Acid, Screenwash and AdBlue using an optical prism test technique and now includes a NEW internal Light feature for ease of use in poor light. Coolant ‐ Tests both propylene and ethylene based anti‐freeze coolant solutions and determines the freezing point. Battery Acid ‐ indicates the specific gravity of the battery electrolyte. Screen Wash ‐ shows the freezing point of screenwash fluids in degrees C. AdBlue – Indicates % concentration of AdBlue additive.
