MISCO Refractometer Q&A Forum
Find answers to many common questions concerning applications, operation, calibration, and maintenance of refractometers:
We are specifically wanting to measure both Engine Coolant and Windshield Washer Fluid for % concentration and Freeze point. The Coolant is water and Propylene Glycol mixed seeking % Glycol in the mixture. The Windshield Washer fluid is a Methanol and Water mix where they want to know % Methanol. These define freeze point.
The Palm Abbe digital refractometer is the ideal way to measure automotive fluids. The refractometer can be programmed with scales for ethylene glycol (EG) & propylene glycol (PG) engine coolants, methanol for windshield washer fluid, and even brake fluid moisture content. You can select from refractometer scales that display freeze point or concentration for any of these fluids. Use the filters on the Product/Digital Handheld page to select a refractometer with the scales that you need. If you cannot find a refractometer that fits your needs, try the Build-Your-Own Refractometer section or call MISCO customer service. We will be happy to custom program a refractometer for you with the exact scales you need.
