REFRACTOMETER RHW-25BRIX-ATC, DESIGNED TO MEASUREMENT THE SUGAR CONTENT,

AS WELL AS POTENTIAL ALCOHOL IN BEVERAGES SUCH AS WINE, JUICE, WORT, ETC.

At its core, a refractometer is a small, hand-held instrument that is usually

includes temperature compensation that occurs in automatic mode, and also differs

waterproof performance. The product will be indispensable for those who consider themselves lovers of winemaking,

and is also equated to specialist brewers. With the help of our device,

You can always carry out the procedure for measuring the volume of sugar present in the wort, as well as juice, or in any liquid solution. Also, you can determine the volume of alcohol in an alcohol-containing liquid. The manufacturers took into account all the subtleties, as well as the suggestions of users, and made a very solid, high-quality product at a very affordable price. 0-25% alcohol and 0-40% Brix sugar.

We propose to consider how exactly the device is used directly. The operation of the refractometer is extremely simple. Before using it, you need to carry out an accurate calibration procedure. To achieve accurate results later, use some distilled water, which you place on the prism.

Then close it with a special glass flask. Water should spread around the entire perimeter, and without air penetrating under the flask. Once everything is ready, point the device at the light and look through the special eyepiece and start rotating it. Thus, the level of sharpness is adjusted. It remains only to visually read the available readings that are on the scale of the boundaries of the blue and white areas. Using an ordinary household screwdriver, ensure that the adjusting screw is correctly adjusted so that, within the eyepiece, the border of the colored areas is exactly at zero. Everything, the device is completely ready for daily operation.

The figure shows the general structure of the device:

Number one is the main prism;

Number two is the glass lid;

Number three is the adjustment screw, which makes the overall adjustment;

Number four is the body of the refractometer;

Number five is the data acquisition eyepiece.

Color scales located in the refractometer allow the user to provide an interpretation of the specific gravity data. There are several convenient formats, which we propose to talk about below:

Brix scale, which provides the user with information about exactly what percentage of sugar is present in the sample.

An alcohol scale will be needed to display the presence of alcohol. For example. To find out the level of alcohol in a wine drink, or in beer, you will need to organize two types of measurements. The first procedure should be performed even before fermentation. Then, you need to perform the second event.

The first dimension is 16 percent;

The second dimension is 4 percent.

Accordingly, the calculation is done as follows: 16 - 4 = 12 percent.

If we talk about the advantages of the device, you should pay attention to the fact that the design is completely universal. That is, having received Brix data on the corresponding scale, the user will be able to convert them to other values. There are special tables for this.

In order to teach the future how to use the device, we offer for consideration a special data ruler, with the help of which the Brix values ​​taken from the refractometer eyepiece can be converted into the values ​​of interest.

S% is a scale for sugar content. It is also called the Brix scale;

S g/l - measurement of the proportion of sugar in the sample. It is possible to identify the product in grape must;

A% - a scale showing the mass fraction of alcohol that is present in the distillate, including finished vodka, moonshine cognac, etc.;

M g / l is a scale for determining the mass fraction of an extract, for example, in wine, or a wine drink;

In% - a scale showing the presence of protein volume. It is required to detect it in the blood serum, as well as in another solution of water.

As an example, we suggest considering a ruler that clearly shows information on measuring alcohol in an ordinary aqueous solution. When a little vodka hits the prism, the device will show data at the rate of 14.5 Brix. We look a little higher and see that the data corresponds to 40 percent alcohol content. Correctly using these or those scales of the ruler presented by us, the user will easily be able to obtain all the values ​​\u200b\u200brequired for him.

Equipment:

Additional protective case

User manual.

The design is specially designed for use with alcoholic beverages, as well as all kinds of syrups that are related to winemaking. The device makes it possible to measure the amount of sugar in grapes. This will help the winemaker find the best time to start harvesting and producing grape wine.

What you should pay attention to:

There are several types of models on the market. All devices updated from a technical point of view receive the Latin letter “N” at the beginning of the name;

Automatic thermal compensation is in the region from 10 to 30 degrees Celsius;

Models such as the RHW-25/ATC as well as the RHW-25/Baume/ATC are typically used to accurately determine the volume of alcohol in grape wine that is produced using juice.

Components.

Below is a list of components with a new design:

light plate;

Adjusting screw for organizing calibration measures;

Function for adjusting the focus;

Retainer required to secure the calibration screw.

Now consider the basic order of use and operation of the device:

1. The front edge of the device should be directed towards the light. Customize the eyepiece so you can clearly see the crosshairs.

2. Next, the calibration procedure is carried out. A small amount, namely a couple of drops of distilled water, is applied to the light plate. The plate is closed. Press it a little so that the liquid can be distributed around the entire perimeter of the prism. It is important to achieve the absence of air bubbles, as well as dry patches. Once distribution is complete, wait a minute for the sample to be on the prism. Now make an additional adjustment of the calibration screw and ensure that the border of the colored areas is at zero. Remember that it is mandatory to set up a refractometer that includes a temperature compensation function at +20 degrees Celsius of the environment. If the room temperature has changed by more than three degrees Celsius, you should recalibrate in order to improve the level of measurement accuracy.

3. The main operating procedure must be carried out after the end of the calibration in the same sequence as the initial calibration. So. Gently open the main light plate and wipe the surface of the prism with a soft cloth. Once the prism is clean, apply a couple of drops of the test liquid to it. Close the plate and then press down a little. Everything, you can read the finished information from the scale. Use the borders of the light area as well as the dark area. All data obtained will correspond to a value that refers specifically to a particular type of solution.

4. After the measurements are completed, clean the device of all the used solution that is on the surface of the prism, as well as on the light plate. Use only damp cotton rags to avoid scratches. After the plate has dried, it should be pressed again.

Device maintenance and warnings for its use.

Zeroing is to ensure that the liquid, as well as the test sample, have the same temperature. If this parameter differs, then every half hour the zero point must be set again.

After you finish using the refractometer, never wash it with copious amounts of water. If liquid gets inside the device, it may fail and require repair;

Each version of the refractometer is a high-precision optical device, so it must be handled with care, without violating the rules of use established by the manufacturer. Avoid touching optical surfaces and avoid scratching them. Store the device in a dry and clean place. The device is subject to corrosion, so precipitation, even in the form of fog, is not recommended. When transporting, carry out careful fixation, avoid hitting hard objects and sharp shocks.

If you use the device in full accordance with the above methods, then it will not require repair for a sufficiently long period of time. Note that the optical properties do not change.

Temperature correction

The factory temperature of the device is 20 degrees Celsius. When using, it is best to timely carry out the temperature compensation procedure according to the table. Important - models that are initially marked with the designation ATC already have at their disposal a function for automatic temperature compensation. Accordingly, for them, temperature correction, carried out on the basis of the data in the table, is not required.

The ATC40 handheld optical refractometer is a professional instrument for measuring the percentage of alcohol in grape must and sugar in wine. The principle of operation of the device is based on determining the refractive index of a sugar-containing liquid, which is proportional to the concentration of sugar.

Here you can buy a refractometer for winemaking, a handheld portable device, has (automatic temperature compensation) and waterproof design. 0-25% alcohol and 0-40% Brix sugar. Indispensable for growers, winemakers, brewers... In fact, a universal model, you can measure sugar in must, juice, in any aqueous solution, you can measure alcohol in an alcohol solution.

Usage:

Using a wine refractometer is very simple. First you need to calibrate it. To do this, drop distilled water onto the prism and close it with a glass cover, the drop under the glass should spread evenly without air bubbles. Point the device at a source of daylight, looking into the eyepiece and rotating it, adjust the sharpness, read the scale readings at the border of the white and blue areas. Using a screwdriver, adjust the adjusting screw (3) so that in the eyepiece, the border of the white and blue areas is exactly at zero, after which the device is ready for use.

1-Prism, 2-Glass cover, 3-Adjustment screw, 4-Body, 5-Eyepiece.

The refractometer's two scales allow you to interpret liquid specific gravity values ​​in several convenient formats:

The Brix scale shows the percentage of sugar by weight.

The alcohol scale displays potential alcohol. In order to determine the alcohol content of wine or beer, two measurements must be taken: the first before the start of fermentation and the second after its completion.

1st measurement 16%

2nd dimension 4%

The device is absolutely universal, knowing the Brix readings on its scale, we can very easily convert them to other values ​​​​we need using special tables.

To simplify the work with the device, below is a ruler with which you can convert Brix values ​​​​(you can see it in the eyepiece of the refractometer on the left) into other values ​​\u200b\u200bthat you need to know in winemaking and brewing.

Ruler for converting Brix values ​​to other values:

S% - a scale for the percentage of sugar, which is called the "Brix" scale;

S g/l scale of the weight fraction of sugar, for example, in grape must;

A% - scale of the mass fraction of alcohol in distillate, vodka, cognac, etc.;

M g/l - the scale of the mass fraction of the extract in wine;

B% - a scale of the percentage of protein in blood serum or other protein solution in water;

For example, now the ruler shows data on the measurement of alcohol in an aqueous solution. This is if ordinary vodka is dropped onto a prism, the device will show 14.5 Brix, which corresponds to (look at the scale above) 40% alcohol content.

Using the various scales of the ruler in this way, you can easily read other quantities we need.
