tyhjiömittarit
Tyhjiömittarit, also known as vacuum gauges, are instruments used to measure pressure in a vacuum. This means they measure the difference between the absolute pressure of a space and the atmospheric pressure. They are essential in many scientific and industrial applications where maintaining a low-pressure environment is critical.
There are several types of tyhjiömittarit, each suited for different pressure ranges and applications. Mechanical gauges,
The principle of operation varies depending on the type of gauge. Some rely on the physical deformation
