Components:

Newly designed components

1----Light plate; 2----Calibration screw; 3----Focus adjustment; 4----Peephole; 5----Gauge screw lock

Operating procedure:

1) Point the front edge of the refractometer at a bright light source and adjust the eye so that the crosshair of the sight is clearly visible.

2) Calibration.

A refractometer with a temperature compensation function should be adjusted at a temperature environment 20°C.

If the operating temperature in the room or measurement location (but not the sample) has changed by more than 3 °C, it is recommended to recalibrate to improve measurement accuracy.

3) The operating procedure is carried out after calibration in the same sequence as calibration. Open the light plate. Wipe the surface of the prism with a soft cotton cloth. Place 2-3 drops of the test solution onto the main prism. Close the light plate and press it lightly, then you can read the scale at the border of the light and dark areas. The readings correspond to the value related to the solution.

4) After measuring, wipe off all the solution from the surface of the prism and light plate with a damp cotton cloth. After drying, the plate must be pressed well again.

Maintenance warnings.

1) Zero setting. The liquid and sample must be at the same temperature. If the temperature varies greatly, the zero point should be reset every 30 minutes.

2) After use, never wash the device with water to prevent water from getting inside the device.

3) Since the device is a precision optical instrument, it should be handled and maintained with care. Never touch or scratch optical surfaces. The device should be stored in a dry, clean place, away from sources of corrosion, and the surface should be protected from fog and mold. When transporting, avoid sudden shocks.

4) If you use the tool in accordance with the specified methods, then it is guaranteed to never become unusable. The optical properties of the device do not change over time.

Temperature correction

The base temperature of the device is 20°C. During operation, temperature compensation should be carried out according to the table. Models marked ATC are equipped with automatic temperature compensation. Therefore, temperature correction according to the table is not required for them.

What is a refractometer?

A refractometer is an optical instrument that measures the refractive index of light in a medium. Refractometry, performed using refractometers, is one of the most common methods for identifying chemical compounds, quantitative and structural analysis, determination of physical and chemical parameters of substances.

The operation of a refractometer is based on measuring the refractive indices of light in various media. If the density of a substance increases, its refractive index increases proportionally (for example, when sugar is dissolved in water). A refractometer reads the relative "weight" of a sample compared to distilled water.

Refractometer Calibration and Use

Wait approximately 30 seconds before you proceed to the next step. This will allow the sample to adapt to the ambient temperature.

Point the refractometer towards natural daylight and look through the eyepiece. You will see a circular area (box) centered at the bottom.

(Figure 1 shows the scale without calibration fluid or any other fluid.)

Tighten the calibration screw until the boundary between the upper blue area and the lower white area meet exactly at the zero mark.
Figure 2 shows what you see during calibration.

Once the refractometer is properly calibrated, it is ready for use. Gently clean the instrument (especially the plate and prism) using a soft cloth, then place 2-3 drops of sample onto the prism. Close the daylight plate.
Figure 3 illustrates what you see at this stage.

	Picture 1 This drawing illustrates what you can see in the eyepiece without any reference. Notice that the entire scale is colored blue. When viewing, make sure you use natural daylight. You should not take readings in the presence of fluorescent light.
	Figure 2 This is what you see after the refractometer has been calibrated. Please note that for proper calibration, the border of the blue and white scale should be exactly at the zero mark when using distilled water as a sample.
	Figure 3 This example shows a scale for measuring grape juice. You can see that the meter shows 23% Brix, the best time to make wine! After finishing the measurement, make sure you clean and dry the refractometer.

Refractometer maintenance

Accurate measurement depends on careful and correct calibration. As a reminder, differences between ambient temperature and sample temperature will reduce the accuracy of the reading. Be sure to wait approximately 30 seconds before taking a reading.
Do not immerse the instrument in water or allow water to get inside.
Do not measure harsh or corrosive chemicals with this instrument because they may damage the prism coating.
Clean the instrument between each measurement using a soft cloth.
A refractometer is an optical instrument. It requires careful handling and storage. With careful use and proper storage, this tool will provide reliable performance for many years.
The air temperature during calibration should be 20° C. However, many modern models come with ATC (automatic temperature compensation), so you don't have to worry about calibration air temperature or sample temperature.

Refractometer RSG-100/ATC (0-32) allows you to measure the density (amount of sugar) of your beer or mash using just 1 drop.

A refractometer is an optical instrument designed to measure the concentration of sugars in aqueous solutions. Concentration is measured by measuring the degree of refraction (refraction) of light in a solution.

Refractometers, most commonly used by homebrewers, do not contain any electronic components.

Using a refractometer is very simple.

First you need to calibrate it: place a drop of distilled water on the glass, close the lid and wait 30 seconds.

Point the refractometer at the light source and look through the eyepiece: measurements are taken using the dividing line between the blue field and the light field (you will immediately understand everything, as soon as you look). This line indicates the degree Brix scale, which you also see in the eyepiece.

Using a calibration screwdriver, ensure that the refractometer shows 0 Brix on distilled water. After calibration, clean the glass, drip wort onto it and read the readings.

HOW TO TAKE READINGS:

Initial gravity is measured very simply, you simply drop a drop of wort onto the refractometer before putting it into fermentation and determine it to BRIX gravity. Final gravity is a little more complicated. When the liquid already contains alcohol, the refractometer gives distorted readings, but there is a special calculator that allows you to determine the exact figures for the final gravity of your beer. It also helps to calculate the final alcohol content.

http://www.northernbrewer.com/refractometer-calculator/

In the first point, from above, recalculate Brix to S.G.

It is not necessary to use it since this refractometer model shows both indicators at once.

Enter the initial and final density in Brix, and the program calculates the actual final density in S.G.

In the last paragraph: Approximate ABV and Original Gravity from current Brix and Gravity converter.

Enter the final density in Brix (what the refractometer shows you), the final S.G - what you calculated in the point above. At the output you get the strength and, to check, the initial gravity in S.G.
