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.
Hello, I am looking for a handheld portable device to measure the % mass ethylene glycol in a glycol / water solution. Thanks.
Very interested, yet ignorant about this technology. I need reliability in testing % NaCl in water softening applications as well as concentrations of sodium hydroxide, hydrochloric acid, and sodium sulfite. Do I need multiple instruments? Can I get the meter to read in ppm of sodium sulfite? Can the meter(s) read in % saturation of NaCl? I am used to reading hydrometers for all but sodium sulfite, can the instruments give the same read out in % acid or caustic? I really do not understand the BRIX scale and how that will look when all I want is the strength of acid or % saturation of NaCl. Thanks,
How do you know when to change DOT brake fluid?
I read that all Palm Abbe refractometers have serial numbers. Is there a way I can tell the serial number for my refractometer?
