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.
Please explain why your Palm Abbe refractometer lists accuracy as 0.0001 nD AND as 0.1 % Brix when an interval of 0.1 % Brix is almost exactly 0.0002 nD. Am I right in thinking the Brix % should be changed to 0.05 or the nD to 0.0002, which? I use a refractometer to indicate the concentration of firefighting foam solution, by comparison with calibration samples and most other digital hand held refractometers on the market list accuracy as 0.0002 nD or 0.1 % Brix. Some popular firefighting foams have quite low RI, which results in having typical solution RIs of 1.3330 - 1.3338 nD, and if the accuracy claimed is twice as good as your competitors, the error on readings could be halved. Note: FPEs working with foam systems often have to report on RIs as low as 1.3332.
I am looking for a chart of what the medication should show up as on the brix scale. I want to use the Palm abbe digital refractometer mostly for Fentanyl, midazolam, morphine pf, ketamine, morphine, meperidine, sufentanil, and astramorph. If you know of where I can find this information that would be greatly appreciated.
I hear a rattle inside my refractometer whenever I shake it.
My Palm Abbe Digital Refractometer reads "No Sample / Detected" What can I do about it.
