The refractometer readout shown above is measuring 30 degrees Brix. Other Types of Refractometers. Digital refractometers require a drop of the tested solution to be placed in a well. That well is illuminated by a light .Remember, refractometers read on a Brix scale rather than actual percent. To get the actual percent, you must multiply the refractometer reading by your coolant’s multiplier (on product data sheet). With most soluble oils the multiplier is 1, so a refractometer reading of 5 multiplied by 1 = 5% concentration. Using a refractometer test, you can maintain your system for efficiency and lifespan. . This instrument requires only a few drops of fluid for glycol testing and requires no adjustment for fluid temperature. . Please find below the Freezing and Boiling Points chart used in our how-to video for both DOWFROST and DOWFROST HD Propylene glycol .
This is your Brix reading in degrees – i.e. 27%. If the reading is not very close to that of your calibration solution, you must adjust your refractometer. The calibration screw is on the handle and often has a cover. Pop off the cover and use a small screwdriver to adjust the sharp line to the proper measurement for your solution.Refractometer Calculator Convert pre-fermentation Brix to gravity, Brix to gravity during and after fermentation, approximate ABV, and original gravity from current Brix and gravity using the Refractometer Calculators below.Adjust the calibration screw: While looking through the eyepiece, adjust the calibration screw until the boundary line between the blue and white areas aligns with the 0°Bx mark on the scale. Your refractometer is now calibrated. Reading a Brix Refractometer. To read a Brix refractometer, follow these steps:(Use this chart to adjust your freeze point up to -35˚F) If refractometerreadingis off scaleor showsa freezepointfor the samplelowerthan-62˚F,use the chartaboveto adjustthe freezepointto -35˚F. To do this, take the coolant sample and dilute it 50/50 with water. Take a new refractometer reading, and match this value to Usingthe reading under
refractometer scale how to read
After the refractometer’s adjustment, the temperature of the testing environment can fluctuate within a certain range (10℃~30℃). Refractometer calibration needs to be at the temperature of the testing environment. If this is difficult, check the calibration chart. However, FJD digital refractometers have automatic temperature correction ATC.this method for homebrewers. You need to take a reading with the refractometer as well as a hydrometer and use this equation: ABV = [277.8851 - 277.4(SG) + 0.9956(Brix) + 0.00523(Brix2) + 0.000013(Brix3)] x (SG/0.79) In this equation, Brix is the Brix reading of your refractometer and SG is the specific gravity reading from your hydrometer. Step 3: Aim the refractometer at a light source and take your measurement. After closing and locking the flap in place, hold the refractometer towards the light and adjust the focus. Then record the reading from the Brix scale. Step 4: . Refractometer FAQs What is a Refractometer? A refractometer is a simple instrument used for measuring concentrations of aqueous solutions such as gases, liquids, and translucent solids. Different types of refractometers are available depending on the application. Refractometers can be handheld, compact, benchtop, Abbe, and Brix as well as different .
4. Hold the refractometer up to natural light or an incandescent bulb to obtain the reading. Look-ing into the eyepiece, one should see a distinct separation between a blue and white section, often called a “contrast” line. If the con-trast line is not directly at zero, then adjust by turning the screw on the top of the refractometer until it

Close the cover of the refractometer and let the water spread evenly on the prism. Look through the eyepiece and adjust the calibration screw until the line representing the refractive index of water (usually 1.000) aligns with zero. Step 2: Prepare Your Sample. Once your refractometer is properly calibrated, it’s time to prepare your sample.Refractometer-Calculator Adjustment Correlation: Terrill Linear Terrill Cubic Novotný Linear Novotný Quadratic Terrill & Novotný Bonham (Standard) Gardner Gossett Reading Before Fermentation (°Bx): Reading After Fermentation (°Bx): Wort Correction Factor:
Brix measurement can be performed by refractive index as well as by density. When measuring pure sucrose content in water, the techniques will deliver the same result. However, for other samples, different results are obtained depending on the instrument (technique) used: e.g., the hydrometer, pycnometer, refractometer or digital density meter.
It will take a little time for a refractometer to adjust to changes in environmental temperature. For instance, if you take a refractometer from a cool air-conditioned laboratory out onto a shop floor on a hot summer day, it will take some time for the refractometer to equalize with the temperature in the shop.
When taking a refractometer measurement of wort, the Brix reading is not necessarily accurate. What is obtained is the Brix WRI (wort refraction index). Only after dividing the Brix WRI by the wort correction factor is the actual Brix known. It is helpful to know that Brix and Plato are nominally the same to 3 Step 5: Adjust the zero point – Look through the eyepiece and locate the scale. Ensure that it is focused and set to zero or the calibration mark. Use the calibration screw or knob to make any necessary adjustments. Step 6: Verify the .the refractometer until it reads zero (Fig. 3). Replace the plastic cap after adjusting the calibra-tion screw to prevent water from entering the refractometer. You can adjust the focus by twist-ing the eyepiece until the scale can be seen clearly. Once the refractometer is calibrated to zero with pure water, dry the surfaces with a clean cloth.
4. If the instrument is properly calibrated, the reading will be 1.3330 less 0.0001 for each degree above 20OC or plus 0.0001 for each degree below 20OC. If the instrument is not calibrated, determine the proper reading (Chart 1) and rotate the adjustment control and depress the READ display button until the display reads correctly. (The shadow .This is where the reading is taken. Then adjust the calibration screw until the meter reads 0 Brix.
