How to choose a reliable scale up to 5 kg: characteristics, types

Choosing the scale, first of all need to determine the weight, he is able to weigh. Popular value of this quantity - 5 kg. At these scales easy to determine the size of the serving, prepare the dough and prepare the vegetables for canning. Of whole chicken or fish easily enters the measuring range.

Features kitchen scales to 5kg

Choosing the balance with the load of 5 kg is important to determine other parameters.

When deciding what product to prefer the measurement, it is advisable to stick to this plan of action:

• Decide which error gives sufficient measurement accuracy.
• Determining the type based on the principle of action.
• The choice of design.
• Determination of the required additional options.
• Design solution.
• Familiarization with the care and use of the rules.

Measurement error

Deviation - a degree of deviation of the mass from its true value. From this characteristic it depends on the accuracy with which work. To find out the true value is impossible, but you can reduce the value of the error.

The smaller the scale interval, the higher the accuracy. Since many recipes contain ingredients in quantities of pairs grams, it is advisable to choose a minimum error.

Another important measure for the minimum value. Step weighing range from 1g to 50g. It is recommended to choose a device to measure the weight of products from 1 g This will allow not only to make the blank with a large mass, but also sophisticated culinary specialties with precise dosing of spices.

Values ​​such as the maximum permissible weight and measurement error, is usually marked on the body, so even without the instructions can be found these two important characteristics.

design

Kitchen scales are available in two types:

• With a flat platform.

The main advantage - the ability to weigh in the bowl, which is used for cooking.

Here the useful function of zero: the empty dishes installed on the platform, and the value of the mass index is reduced to zero. After that packaging is no longer involved in the measurement process. Another flat surface suitable for ready-made pieces laid out on a plate.

Large fruits and vegetables (pumpkin, watermelon), it is advisable to lay on a flat plate. Meat, poultry, and other foods, the amount of which can not afford to stay in a special container rationally placed on the platform.

• With the cup.

Suit lovers baking. Suitable mixing multicomponent compositions.
Models available with removable and non-removable cups. The folding design is easy to use, as the container can be washed without fear pour.

There are models that are convenient for storage. The removable cup packed themselves, to save space in the closet.

It is important to realize that a flat or three-dimensional objects in a bowl can not fit.
Separate measuring scale inside the bowl allows to determine the weight of the liquid and its volume.
It is impossible to make an unambiguous choice in favor of a design. In each of them there are pluses and minuses. And choose certain scale needed because of the nature of prepared dishes.

Types of kitchen scales up to 5kg

Balance, operating in the range up to 5 kg can be divided into two categories:

• Mechanical.
• Electronic.

mechanical scales

These measuring instruments, in turn, are:

• Manual.
• Desktop.

Manual ( "steelyard").

This basic balance scales. Types of execution in different countries her, but the essence remains the same.

The maximum value that provides a measure of - 10 kg. But there are "steelyards" maximum load of 5 kg.

mechanical Desktop.
The designs are capable of measuring high weight (20 kg), but there are models with smaller limit value.
Principle: in them a spring which under the influence of the subject lying on her stretched, thereby shifting the arrow on the measurement scale.

Many housewives are choosing this type, since they have a number of positive characteristics:

• Low cost.
• It does not require any power source (either from the mains or batteries).
• Resistant to external influences. Not afraid of water, and the kitchen is important.
• Long service life.
• Easy repair. It is possible even at home.

These scales are even, and the old way of measuring is still not lost its relevance. But there are also disadvantages:

• A large degree of uncertainty. In mechanical measuring devices accuracy equal to the price of division on the dial. One division is up to 25 grams or more. In qualitative scales this value is less, but then the price of the product is significantly increased.
• Over time, the spring is able to stretch and measurement error increases.
• No additional options.

Electronic balance
Very popular measuring instrument. It is among this type of scales observed the largest selection of products with maximum weight of weighing up to 5 kg.
They are gradually replacing the mechanical design market goods.

Operating principle.
As a main part in the design of electronic scales isolated strain sensor (force sensor).

Whose value ranges from 0 to 50 mV. Then the signal is input to an analog-to-digital converter (ADC) which converts it into a digital signal. This signal is reacted with a microprocessor that translates the impulse into a quantitative value of the mass.

This chip - the main part of electronic scales, their "brain". The microprocessor interacts with a keyboard and display.

Advantages and disadvantages.
Electronic scales confidently occupied a niche among customers. Advantages compared with mechanical, are obvious:

• Bulky parts (spring) load cell replaced compact. Thanks to this electronic measuring devices have become smaller and lighter than their mechanical counterparts.
• They are reliable and durable. Since there are no moving parts, there is no frictional force between the parts, respectively, reduced wear.
• Resistant to mechanical stress.
• Have a variety of additional options.
• The maximum error of electronic kitchen units not more than 1 gram.

Among the shortcomings release:

• power required (network, battery or batteries).
• The high purchase price.
• Costly repairs.

Function kitchen scale

Additional options are available only in an electronic version of the measuring device.

Electronic models, depending on the complexity programmed to perform the following functions:

• The display mode of time. When the scales are turned off, the display shows the current date and time.
• Indication of battery charge. It used if the balance is running on batteries or battery.
• Display mode overload. If the product weight exceeds the limit value, then the corresponding message appears on the screen.
• Automatic activation and deactivation. This option preserves the surface and control keys clean, as well as saving energy or charge batteries. When not using the specified time, they go into standby mode, turning the display into the clock display mode.
• Successive weighing. Useful when multi-component composition of the product. After each new reset value of the product, and at the end of the measurement is shown the total weight of ingredients.
• Accounting tare (zero). Resulting readings to zero when standing on the scale capacity.
• Measurement of the liquid volume. This function is possible in a mechanical and electronic scales, if they are equipped with a special cup deposited inside the graduations corresponding to the liquid volume.
• Built-in timer.
• Built-in thermometer.
• Accounting calories, cholesterol, proteins, carbohydrates and fats in the product.
• Transferring data to a computer or phone. This function is used as part of the "smart home".

There are other features. This depends on the developer.

Design

Kitchen scales - the device, which is often not removed in the closet, and put on the table. Therefore, the design in this case is given extra attention. They must integrate harmoniously with the interior of the premises where installed, to combine beauty and functionality.

Enclosure material selected from expensive plastic or metal. This will ensure a pleasant product appearance and durability. Glass and chrome surfaces add chic.

There are models manufactured with rubberized buttons or closed film - it will provide protection from moisture and eliminate damage due to water.

The unusual design of the cup, the patterns on the body and platform, color solutions - every woman will be able to choose the device to his liking.

Care

Each type is individual devices, but a number of general rules of operation are applicable to any measuring instrument.

• Before you start, you want to examine for the presence of lesions. This is required to comply with the machine operating on the network. If damaged wires - operation is prohibited. With the destruction of the body - it is not recommended.
• It can not be placed in direct sunlight or near hot cooking equipment.
• Prohibited immersion in water. For cleaning and cleaning is recommended to use a damp cloth or sponge.
• Using abrasives scratches the surface and spoil the appearance of the product.

Compliance with these simple rules will allow the unit to operate without failure.

Verification of the balance
Verification is an exact calibration weight values ​​compared with the standard weights. The primary and only purpose calibration performed at the factory prior to sale.

malfunctions

Broken are those devices that are either not included or show an incorrect value of the measured parameter.

More faulty call unit, wherein the measurement error exceeds a documentary.
Causes of failures:

• Mechanical action on the scale.
• Violation of the conditions of use.
• Marriage, admitted at the factory.

There are two types of fixes:

• Average. Calibration. It applies if shot down parameters. It passes without replacement of parts.
• Capital. It requires replacement of assemblies and mechanisms.

It is divided into:

• Guaranteed. If the failure was caused by the manufacturer.
• Not a guarantee. Buyer's guilt was proved.

Kitchen scales subject useful in the kitchen. Choice is due to the technical characteristics and aesthetic preferences of the buyer. Each woman decides for itself what parameters to guide the instrument to work with maximum efficiency and pleased appearance.
