Stopwatch "Slava" is characterized by high measurement accuracy, simplicity and ease of use. Initially, this device was intended for professional athletes, but can be used to measure time periods in sports and other industries.
The
Stopwatch
is equipped with two second hands, allows you to detect intermediate measurement values without interrupting the overall time measurement cycle. When pressed, the split pauses the red hand at a certain intermediate sign - while the black second hand continues to move. Pressing the split key again makes it possible to return the red arrow to the black one, and then they move at the same time.
Structurally, the stopwatch mechanism consists of 3 wheel systems:
• Power engagement of the drive (on the escape wheel from the spring);
• Counting engagement for the central second hand;
• Optional drive for split second.
The accuracy of measuring the time intervals of the Slava stopwatch is 1/10 sec. – this can be achieved due to the highest class of accuracy of the components of the mechanisms. At the same time, in order to achieve high accuracy, the power and counting wheel systems are separated in the device.
The stopwatch is made in a durable metal case, and its weight is only 230 g. Such a device will help to provide accurate control of time intervals with several intermediate values.
