To help you select a digital pressure gauge, the following tips my be helpful:
Pressure is defined as the force applied over an area, such as the wall of a container or as part of a manufacturing
process. The common English unit for pressure is pounds per square inch, or psi. To convert from psi to other units, see the conversion table below.

How To Pick a Pressure Gauge
If your system or process depends on pressure and vacuum being measured and controlled, it is imperative that the correct device is chosen. Long-term reliability and cost control depend on picking the right device for a specific application. For example, one would not buy a high-cost precision test gauge for an application involving pressure spikes and vibration. Major factors to consider are:
Process: the pressure sensing element will be exposed to the process media, so select a gauge material that is compatible with your process media. If the process media is corrosive or extreme over-pressure exists, a diaphragm may be required.
Pressure Range: normal pressure range dictates the full range of the gauge you need. ANSI B40 recommends that the operating pressure occurs in the middle half (20 to 75%) of the scale.
Environment: in some cases, the ambient environment can be more harmful to a gauge than the process itself. If vibration, caustic environment, or high operating and ambient temperatures exist, a more rugged, sealed gauge will be needed.
Accuracy: accuracy required for your process depends on the sensitivity of errors in your pressure measurement.
