Why do I get very different reading from hydrometers (2) and BRIX (0-32) refractometers?
I just calibrated a lot of 10 refractometer units with distilled water then compared readings from two hydrometers and 10 refractometers and I get a difference of 3.61 to 4.11 BRIX units from a know sugar solution concentration (1.046 gravity or 11.39 BRIX).
All tools , hydrometers and refractometers, read zero (0) with distilled water. Both hydrometers give consistent readings from one another. All ten refractometers gave readings within +/-0.25 BRIX from the know solution concentration. I assume I am familiar enough with the refractometer usage because I used this tool many time before in school (labs). Testing and calibration was done under good condition ~22°C.
What am I missing?
After investigation, it appear the units are defective. Most plausible cause being the wrong prism installed in the units according to the manufacturer technical support.
Thanks for stopping by this question.
Have you compensated for temperature?
I am not familiar with that calibration solution for refractometers. The only calibration soln that I have used is at a 28% Brix Calibration.
With luck I have found some online information that should help you.
Some refractometers require a calibration fluid other than distilled water. In particular the Brix 28 - 62%, Brix 45 - 82%, and Brix 58 - 90% refractometers require a calibration fluid containing a known amount of sugar. The 28%, 45%, and 58%, refer to concentrations of sugar in a solution measured by WEIGHT. A very simple method of making your own calibration solution would be to measure out your sugar, i.e. 28 grams, and then add 72 grams (72 cc) of distilled water to give you 100 grams of 28% sugar solution. Be sure to stir the solution to completely dissolve the sugar before you use it for calibration. If you do your measurements with care this will be close enough for common work.
Hummmm, Light Refraction Vs Soln Density
The last thing you need is a conversion from DENSITY- BRIX-REFRACTIVE INDEX.
A Conversion Chart would work for this or do it yourself.
(Specific Gravity from Density using Water = 0.99823 g/cc at 20 degrees Celsius)
