Hand held pneumatic pump is a portable pneumatic pump and pressure source mainly used for calibration work. It uses air as the pressure medium and has built-in fine adjustment control and overpressure protection functions. Hand held pneumatic pumps typically connect standard pressure gauges or gauges to the calibration gauge through hoses and rotatable joints, making them suitable for calibrating various pressure gauges. Its structure includes a booster pump, cylinder, piston rod, fine adjustment, release valve, and pressure output interface. It is easy to operate, structurally reasonable, and has good sealing performance. It is suitable for fields such as metrology, scientific research, and industrial and mining enterprises.

Main features ：

1. Portability：Hand held pneumatic pump has a small volume, light weight, and is easy to carry and use.

2.Simple operation：By pushing and pulling the piston rod to perform reciprocating motion, the cylinder volume is changed to generate pressure output, and the operation is simple and easy to understand.

3.Multifunctionality：Suitable for on-site debugging and instrument calibration, it can provide a stable pressure source and is suitable for the calibration of various pressure indicators.

4.Good sealing performance：Exquisite fine-tuning and fast interface design ensure good sealing performance and stable pressure output.

5.Wide applicability：Suitable for multiple fields such as metrology, scientific research, and industrial and mining enterprises.

Application scenarios：

Hand held pneumatic pumps are widely used in the following scenarios：

1. On site debugging: Used for on-site debugging in pressure process control

2. Instrument calibration: Provide a pressure source for instrument manufacturers to measure pressure, used for instrument calibration

3. Scientific research and industrial applications: Used for various pressure testing and calibration work in scientific research and industrial and mining enterprises
