A gas syringe is used for measuring volume of gas. There are many different tests for identifying what gas it is.
A bubble counter - saw one of these in action at a science show the other day. Looks fairly effective.
Cephalometer
An instrument that measures very high temperatures is called a pyrometer. The most modern type of pyrometer measures thermal radiation through pyrometry.

An argon gas analyzer measures the purity of Argon gas. The analyzer can be used to determine the actual content of Argon gas in a specific sample.
Pressure guage
A manometer is an instrument that can be used to measure the pressure in an enclosed container that is filled with gas. The manometer is sometimes called a pressure gauge.
Usually in homes its just the gas meter that is checked often by city workers.
This instrument is a balance.
A tiltmeter measures changes in the tilt of the earth. :)A tiltmeter is an instrument that measures changes in the tilt of the earth. :)
A calorimeter measures heat. In contrast, a thermometer measures temperature.A thermometer bolometer - an instrument that measures heat radiation; extremely sensitive calorimeter - a measuring instrument that determines quantities of heatHeat is measured with a ThermometerThermometerThermometer or calorimeterThermometerthermometerHeat is measured with a thermometer.
The density of gas can be measured by using a scale! Fill a container with gas and weigh it, then use a vacuum pump to evacuate the container, then weigh the container again. The difference in weight is the weight of the gas.
A thermometer measures molecular energy.
