A Refractometer is a precision optical instrument designed to measure the concentration or mixture ratio of water soluble fluids. It measures refractive index, the speed at which light passes through a liquid. The denser the liquid the slower the light will travel through it, and the higher its reading will be on the refractometer. There are four main refractometer types: Traditional Analog Refractometers, Digital Handheld Refractometers, Inline Process Control Refractometers and Refractive Index Sensors, and Desktop, Benchtop or Laboratory Refractometers.
MISCO Refractometer, in business for more than 60 years, is a respected industry leader in the field of refractometry. We maintain this leadership position because refractometers are all we do - just refractometers. Refractometers are not just a catalog item or sideline business for us, they ARE our only business. That's what makes us unique.
Our strategy is simple - we are dedicated to making refractometers useful instruments that are easy for people, not just scientists, to understand and use. We do this by demystifying arcane scientific methods and offering real-world solutions for fluid measurement applications. We pride ourselves on being the information warehouse for the refractometer community.
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.
Hi, will your hand held (both glycerin/ glycol) read below zero. In Utah we are required to provide -0 readings. Please let me know.
What is the difference between the traditional analog Brix refractometer and the electronic digital handheld for Glycol testing? What are the benefits to having one over the other?
Looking for a refractometer to test metalworking fluids for grinding at concentrations from 0.5 to 4%, current analog scale 0 - 15% is too large and we cannot see concentration movements - have you got anything?
