gas thermometer

For such measurements a gas thermometer is more suitable.

The ideal gas thermometer is, however, not theoretically perfect for thermodynamics.

Such systems are known as "ideal gas thermometers".

In order to make the idea concrete, temperature is defined in terms of operations with the gas thermometer.

A gas thermometer measures temperature by the variation in volume or pressure of a gas.

Most thermometers are originally calibrated to a constant-volume gas thermometer.

The ideal gas law allows one to measure temperature on this absolute scale using the gas thermometer.

Due to its low boiling point, helium is also suitable for low temperature gas thermometers.

Although it is not a particularly convenient device, the gas thermometer provides an essential theoretical basis by which all thermometers can be calibrated.

Gas thermometer principle: relation between temperature and volume or pressure of a gas (Gas laws).

The constant volume gas thermometer plays a crucial role in understanding how absolute zero could be discovered long before the advent of cryogenics.

In 1848, he extended the Carnot-Clapeyron theory still further through his dissatisfaction that the gas thermometer provided only an operational definition of temperature.

Helium gas thermometers are one of the standard instruments of the International Temperature Scale (1990).

Another type of thermometer that is not really used much in practice, but is important from a theoretical standpoint, is the gas thermometer.

• A flue gas thermometer can tell you if the temperature of your appliance's flue is within the safe range specified by the manufacturer.

G0110 Gas thermometer Thermometer whose principle is based on the variations of pressure or volume of a gas as a function of temperature.

The results of this metrology are in good agreement with those obtained with the PVT gas thermometer and those obtained by radiometry.

Other thermometers (e.g. mercury thermometers, which display the volume of mercury to the observer) may now be constructed, and calibrated against the ideal gas thermometer.

Detection of radioactive emissions using a Geiger counter, determination of the absolute zero of temperature using a gas thermometer, and other experiments illustrating the analysis of experimental data.

As a practical matter it is not possible to use a gas thermometer to measure absolute zero temperature since the gases tend to condense into a liquid long before the temperature reaches zero.

These include helium vapor pressure thermometers, helium gas thermometers, standard platinum resistance thermometers (known as SPRTs, PRTs or Platinum RTDs) and monochromatic radiation thermometers.

We are also the UK agents for the following: SIKA: Pipe& Exhaust Gas Thermometers, Portable Dry Block Temperature Calibrators and Flow Switched and Flow Senesors.

The ideal gas thermometer can be defined more precisely by saying it is a system containing an ideal gas, which is thermally connected to the system it is measuring, while being dynamically and materially insulated from it.

Joly also invented a photometer for measuring light intensity, a meldometer for measuring the melting points of minerals, a differential steam calorimeter for measuring specific heats and a constant-volume gas thermometer, all of which bear his name, together with one of the first color photographic processes, the Joly Colour process.
