Which statement best describes the typical equipment setup for an air-pressure tightness test?

• A. A battery of lasers and spectrometers
• B. A calibrated pressure test pump or regulator, a pressure gauge or digital manometer, and fittings to isolate the tank
• C. Only a watch and clipboard
• D. A heat gun and temperature probe

Answer: (B)

The essential idea is that an air-pressure tightness test needs a controlled pressure source, a way to read that pressure, and hardware to connect to and isolate the tank so you can pressurize and hold it. A calibrated pressure test pump or regulator provides the known pressure, a pressure gauge or digital manometer lets you monitor the exact pressure, and fittings to isolate the tank keep the test isolated from the rest of the system. Lasers and spectrometers aren’t the right tool for this basic method—they’re used for other types of leak detection, not simply measuring pressure buildup and loss. A watch and clipboard don’t measure or control anything, and a heat gun with a temperature probe focuses on temperature, not the pressure or sealing of the tank. Using the right combination of a calibrated pressure source, precise pressure measurement, and proper isolation fittings ensures you can accurately pressurize, monitor, and observe any pressure drop indicating a leak.
