In real life, when we use a pressure gauge, the measurement result is not actually the real pressure of the object being measured.
1. From the principle of a pressure gauge, the pressure it measures is the difference between the actual pressure and the atmospheric pressure.
If the actual pressure is smaller than the atmospheric pressure, the pressure measured at this time is called vacuum degree. It can also be called negative pressure.
2. If the actual pressure is higher than the atmospheric pressure, the pressure measured is called gauge pressure.
For questions about pressure gauges, please feel free to contact us.
