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, I’m interested in purchasing a refractometer, but I am not sure which type is suited to my needs. I plan to use it in order to verify concentrations of Urea concentration. The temperature of the solution will be 35 degrees Celsius, and I want to use high concentrations, 6M-8M Urea. Can you please advise as to which device is best suited to my needs?
How Can You Shut Off the MISCO Palm Abbe Digital Refractometer?
Need a refractometer that will read glycerin based antifreeze for fire suppression. Firefight GL is the product we use. Thanks.
I would like to obtain some additional information regarding your PALM ABBE PA202X-011-014 ethylene glycol refractometer. Our enquiry is related to the use of the refractometer for measuring runoff and surface waters for ethylene glycol. Specific questions are:
1. Units of measure. Does the instrument have the capability of reporting measurements in mg/L?
2. What is the range (lower detection limit and upper limit) of detection of the instrument in mg/L?
3. If there is an upper range, is there a procedure specified for sample dilution?
4. Are there any properties of the matrix (water) that may interfere with the analyses (e.g., suspended solids, dissolved solids, pH)?
5. What is the precision and accuracy of the measurements (+/- in terms of mg/L)? Does the accuracy/precision vary according to sample concentration?
6. Could you provide a pdf of the operating manual for our review?
