There are many varieties of thermometers. Each species 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 mainly made of glass or quartz, so the temperature that he 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 manometer (pressure gauge). Often use constant volume meters. In such devices, the gas temperature varies with pressure. The limit of temperature measurement by such a thermometer is 1300 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 the expansion of the liquid during heating, only inert gas is used here as a working substance.
Benefits
The device allows you to measure temperature in the range from 270 to 1,000 degrees. It is also worth noting the high accuracy of the device. Gas thermometer has a strong side - reliability. The cost of the devices is 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 to get a really high-quality version that will be accurate in operation and will last as long and efficiently as possible.
Scope of application
A gas meter is used to determine the temperature of substances. It 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, gas thermometers of constant volume are used for the virial coefficient. This type of thermometer can also be used for relative measurement using a dual device.
A gas thermometer is mainly used to measure the temperature performance of certain substances. This device is widely in demand in the field of physics and chemistry. When using a high-quality gas thermometer, high accuracy is guaranteed. This type of temperature meter is very easy to use.
