What are the different scales of a refractometer?
Measuring ranges: 0 – 32 °Bx (Degrees Brix)…
- 0.2 °Bx (Degrees Brix)
- 1 °Oe (degrees Oechsle)
- 0.2 °KMW (Klosterneuburger Zuckergrade)

What liquid is used to calibrate a refractometer?
AG Fluids are aqueous solutions that cover the range 1.33-1.40 RI (0-40 °Brix equivalent) and have a shelf life of 12-months. They are ideal for calibrating refractometers that have temperature control in both food and industrial applications as well as instruments that have AG Fluid temperature compensation.
What is the difference between TSS and Brix?
Brix doesn’t differentiate between the different sugars but indicates the total content of all sugars. The °Brix, measured at 200C, is said to be the amount of total sugar in fruit. So, 50 Brix means the fruit has 50% of sugar (or TSS).
How do you read the scale on a refractometer?
Place a small amount of liquid (usually 2–5 drops) on the prism and secure the cover plate. This will evenly distribute the liquid on the prism. Point the prism end of the refractometer toward a light source and focus the eyepiece until the scale is clearly visible. Read the scale value at the point where the dark and light portions meet.
What kind of scale does a veterinary refractometer use?
Veterinary clinical refractometers typically have two or three scales (figure 2). The scale used to measure specific gravity is normally found on the right hand side and is typically labelled as U.G. (urine gravity) or S.G. (specific gravity) with a range of 1.000-1.030 or 1.000-1.040 Figure 2. Clinical refractometer scales (from amazon.com)
Do you need specific gravity scale for Brix refractometer?
A Brix Refractometer that includes a specific gravity scale. You won’t have to do conversions between Brix and gravity when doing measuring, you’ll get the two index in one time. Best of all, it only requires a few drops of liquid for an accurate reading. No need to lose a whole hydrometer test jar of beer or wine in the process.
How is a Refractometer used to read percent salinity?
To make the conversion easier, refractometers are available with scales that are calibrated to read the desired value, in this case, percent salinity. Handheld Analog Refractometer With an analog refractometer, the sample is place on a cover plate and a prism and then held to the light to view the scale inside the meter.
