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.
What is the difference between freezepoint and burst point when testing with a refractometer.
Can the Palm refractometer be used to check Trieythelene Glycol?
I am interested in the VIP Inline Process Refractometer, and I have a few questions: 1) what is the min/max flow rate through the device? 2) what are the inlet/outlet connections? NPT? what are the sizes? 3) is the process liquid usually pumped in? what is the pressure rating? 4) what are the outputs? is specific gravity an option? I see the concentration %, is that for a programmed chemical?
We have a PA203X refractometer. When using this to test % PG in water, is it possible to get a false positive at low levels (e.g., 0.1, 0.2)? Does the turbidity of the sample have any effect?
