What does a gas fitter use to measure gas pressure?

Manometer
Thermometer
Hygrometer
Caliper

The correct answer is: Manometer

A gas fitter utilizes a manometer to measure gas pressure accurately. This instrument is specifically designed to gauge the pressure of gases in a system. It operates based on the hydrostatic pressure of a liquid column, allowing for precise readings of both positive and negative pressures. The manometer is essential in ensuring that gas appliances and systems function safely and efficiently, helping the gas fitter to diagnose issues and verify that the pressure levels are within the required specifications. Other instruments mentioned, such as a thermometer, are used for measuring temperature, a hygrometer measures moisture levels in the air, and a caliper is utilized for measuring dimensions. None of these tools serve the function of measuring gas pressure, which is why the manometer is the correct choice in this context.
