The positive and negative pressure air sources can be connected to the calibration bench at the same time and switched through the reversing valve without shutting off the air source; the pressure can be accurately adjusted through the fine-tuning valve, which is simple and quick to operate, making it easy to calibrate the vacuum pressure gauge. In addition, the device can also use a separate air source (positive pressure or negative pressure) to perform calibration work.
