There are many varieties of thermometers. Each type has its own characteristics and advantages. One of the most popular meters is a gas thermometer. This device is distinguished by its practicality and durability in operation. These devices are made mainly of glass or quartz, so the temperature that it measures should be low or not too high. Modern models differ from their predecessors, but there are no fundamental changes in the operation of new devices.
Features
A gas thermometer is an analog of a pressure gauge (pressure gauge). Often, constant volume meters are used. In such devices, the temperature of the gas varies depending on the pressure. The limit of temperature measurement with such a thermometer is 1,300 K. The presented types of thermometer are in great demand. Moreover, new, improved models are presented on the modern market.
The principle of operation of a gas thermometer is identical to a liquid meter and is based on the effect of expansion of a liquid when heated, only an inert gas is used as a working medium.
Benefits
The device allows you to measure the temperature in the range from 270 to 1,000 degrees. It is also worth noting the high accuracy of the device. The gas thermometer has a strong point - reliability. At a cost, the devices are quite affordable, but the price will depend on the manufacturer and the quality of the device. When buying a device, it is better not to save money and purchase a really high-quality option that will be accurate in operation and last as long and efficiently as possible.
Scope of application
The gas meter is used to determine the temperature of substances. Can be used in specialized laboratories. The most accurate result is shown when the substance is helium or hydrogen. Also, this type of thermometer is used to measure the operation of other devices.
Often, constant volume gas thermometers are used for the virial coefficient. This type of thermometer can also be used for relative measurement using a dual instrument.
Gas thermometer is mainly used to measure the temperature of certain substances. This device is widely demanded in the field of physics and chemistry. When using a high-quality gas thermometer, high accuracy is guaranteed. This kind of temperature meter is very easy touse.
