What is a Refractometer?

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.

About MISCO Refractometer

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.

  • Refractometer for Measuring Ethylene Glycol Run-Off.

    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?

  • Change Battery in Palm Abbe Digital Refractometer.

    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?

  • Measuring Alcohol and Sugar with Digital Refractometer.

    We use your Palm Abbe PA201 digital refractometer for making sorbet, and love it! But we're confused as to how it operates on solutions that contain sugar and alcohol in combination: the readings don't seem to make sense. Is there a way to compensate for this?

  • Refractometer to Measure Balling in Distillers Mash.

    Can your digital refractometer be used to determine balling (sugars) in distillers mash? The standard has been to use a balling hydrometer. Also would there be one to determine alcohol in the fermenting mash? The max is around 9% by volume.

Build Your Own Refractometer

While we pride ourselves in having one of the largest selections of refractometers available, we recognize that every user is different and that there may not be a one-size-fits-all solution to your measurement needs. Build-Your-Own Refractometer allows you to design a custom refractometer to your exact specifications. Just select the desired number of scales, choose protection options, and then add accessories to your design - truly making it your own. When you're done you can choose to print a custom quote or place the order immediately! Give it a try! Of course, call us anytime for personalized service. 866-831-1999
