FAQ

• Analog pressure gauges: Use a needle to indicate pressure on a dial. They are simple, reliable, and do not require a power source.
• Digital pressure gauges: Provide a digital readout of the pressure. They are typically more accurate, offer additional features (like data logging), and require a power source.

It is recommended to calibrate pressure gauges at least once a year. However, the frequency may vary based on the application's criticality, the operating environment, and the manufacturer's recommendations.

Pressure gauges are typically made from stainless steel, brass, or plastic. The choice of material depends on the application and the type of fluid or gas being measured. Stainless steel is common for high-pressure and corrosive environments, while brass is used for less demanding applications.
