A stopwatch is a special device that can measure time very accurately, down to a fraction of a second. Often they are used for measurements with an accuracy of 100th of a second. Now the era of development of modern technologies has come. This made it possible to measure time as accurately as possible.

History of stopwatches

It all started with the advent of primitive watches, which have appeared since time immemorial. At first there were sundials, then water, sand, and fire were also used. But they were good for knowing approximately what time it is, but not suitable for obtaining more accurate data. Measurements of this kind have always given an error of several minutes, and even up to 30 minutes.

If we talk about slightly more modern watch movements, they were invented by Christian Huygens in 1657, who was originally from Holland. The inventor first came up with an idea and realized it with the help of a pendulum. In the first Huygens devices, the daily error rate did not move more than tenseconds. So slowly the evolution of watches took place. However, they could not match the stopwatch despite being accurate.

When electronics began to develop actively, the appearance of electronic stopwatches became logical. This invention has become a favorite tool for physical education classes for physical education classes. Therefore, we can say with confidence that every student is familiar with this device.

Further with the development and spread of computers, stopwatches have evolved into programs that can also measure the length of time with maximum accuracy. There are even online versions of the devices.

Description of mechanical stopwatch SOPpr 2a 3 000

The presented stopwatch has a mechanical principle of operation, it is single-hand. The work of the internal mechanism is interrupted. With it, you can easily measure such periods of time as: minutes, seconds and even fractions of a second.

The price of a stopwatch division is 0.2 s. The scale here is sixty seconds. Also, the model is equipped with a thirty-minute counter, its division value is one minute.

The peculiarity of the device is that it contains 15 ruby stones, the caliber is 42 mm. The developers also installed a spring-type engine on an anchor stroke and an oscillatory balance system. As for the oscillation period, it is 0.4 seconds.

In order to make it easier for the user to control the arrows, the developers equipped the mechanical stopwatch SOPpr 2a 3 000 with a special lever-type devicesimplified action. To start the mechanism, as well as stop it or return the arrows to zero, you must press the winding head sequentially. At the same time, the mechanical stopwatch SOPpr 2a 3 000 works at one spring plant for approximately eighteen hours. The device (dial) is covered with a white enamel layer, while the hands and numbers are black.

As for the accuracy class of this model, it is the third one. For thirty minutes, a slight error of ±1.6 is allowed. The stopwatch can be operated at temperatures from -20 degrees Celsius to +40.

Advantages of the described device

The following advantages of the described stopwatch can be distinguished:

• it provides manual timing control;
• clockwork is interrupted if necessary;
• due to the fact that this one-button stopwatch is very convenient to use;
• time with such a device is measured not only in seconds, but also in minutes and even fractions of a second;
• thanks to ruby stones, it was possible to achieve maximum data accuracy;
• device works with a full spring for almost 19 hours, which is user-friendly;
• chrome-plated metal case looks stylish and protects from damage;
• Usually, sellers of mechanical stopwatches SOPpr 2a 3,000 give buyers a one-year warranty on the device.

As you can see, this device has many advantages that you will definitely like.

Where is the stopwatch used?

Currently, SOPpr 2a 3000 mechanical stopwatches are used in the following areas:

• In sports training, if we are not talking about power sports. The device is necessary in order to measure the length of time required by the athlete to cover the distance and so on.
• In factory and research laboratories.
• In the laboratories of schools, universities, technical schools and other educational institutions.

Also, the device is used by many housewives in everyday life. You can't do without it in military affairs, when it is necessary, for example, to detect the flight time of a projectile in order to calculate the moment of hitting a target.

The stopwatch is an essential part of many people's lives. Thanks to this invention, life can be streamlined and you can understand how much time it takes.
