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.
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?
Do you know of a refractometer that measures the shelf-life of DEF? I’m not as concerned about our contamination as I am the risk. I’ve heard that comes from it sitting idle in a tank for too long.
Do I need to change the batteries in my Palm Abbe Refractometer if I receive the message, "Warning! Low Battery?"
Do you refurbish refractometers if we send them back?
