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.
Which hand-held digital refractometer would be best for checking specific gravity of industrial battery electrolyte (sulfuric acid and water)? Need a minimum range of 1.100 to 1.350
We have a Palm Abbe Digital Refractometer #PA202. Our battery is running low. What device would be used to remove the door to replace the battery? What type of battery is needed?
Why is my Palm Abbe Digital Refractometer reading "Sample Out Of Range?"
I'm interested in testing calcium chloride (CaCl2) at a 30% concentration. This would be to verify identity of totes. Is this possible with a refractometer?
