What can compound gauges measure?

Compound gauges are specifically designed to measure a range of pressures that include both above and below atmospheric pressure. They typically provide readings in terms of gauge pressure (above atmospheric pressure) and vacuum pressure (below atmospheric pressure). This dual capability allows them to be used in a variety of applications where it is important to know both the positive and negative pressures relative to atmospheric pressure.

Additionally, many compound gauges can include a temperature measurement feature, which allows them to provide readings of both pressure and temperature simultaneously, thus facilitating a comprehensive understanding of the operating conditions in various systems. This multifaceted measurement capability is crucial in many engineering and industrial contexts, making compound gauges versatile and essential tools in any scenario where pressure variations in relation to atmosphere are being monitored.
