WebCompound pressure measures both positive and negative (vacuum) pressures. A gauge reading gauge pressure only, that is positive pressure, usually will not be damaged if full vacuum is applied to the gauge. However, if it is a requirement to have the gauge dial display both positive and negative pressure, consider a compound pressure gauge.
