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.
Hi, will your hand held (both glycerin/ glycol) read below zero. In Utah we are required to provide -0 readings. Please let me know.
If a refractometer is tested with distilled water and consistently gives 32 degrees as the freeze point, would a certified calibration still be necessary? I am trying to understand how the refractometer could be outside of its specifications and require a certified calibration if it is consistently giving the expected reading with a control fluid such as distilled water. Also, how often does MISCO recommend that the digital refractometer receive certified calibration? Any information that could be provided is greatly appreciated!
I need to know the percent volume of my glycol?
How accurate is your refractometer when alcohol is present? Can I measure R.S. [residual sugar] in wine? thanks
