Digital pressure gauge also known as digital pressure gauge, has a built-in pressure sensor and is a high-precision pressure gauge that integrates pressure measurement and display. It has the characteristics of anti vibration, high display accuracy, high stability, zeroing, and automatic standby. This series of digital pressure gauges is powered by batteries. Due to the use of low-power processor chips, it has a long battery life, automatic standby and one key reset functions, and is easy to use. It can replace mechanical pressure gauges in various fields such as portable pressure measurement, equipment matching, and standard pressure calibration equipment.
