1、 Overview of Micro Pressure Pump
BR-016S PortableMicro pressure pumpIt is a manual pneumatic pressure source. It has the characteristics of light weight, small size, precise debugging, easy portability, wide working temperature range, lightweight pressurization, simple operation, and convenient use. Structurally, the calibrator adopts a deceleration device, corrugated tube structure, and fine and coarse adjustment. After fine grinding, the calibrator's fine adjustment output is accurate, resulting in high work efficiency.
2、 Technical parameters
1. Pressure range: （-70～200）KPa；
2. Operating temperature:- 20～50℃；
3. Dimensions: 70 × 70 × 200mm;
4. Weight: 1kg;
5. Measurement medium: It is a clean and non corrosive gas.

3、 Characteristics of Micro Pressure Pump
1. Small size, light weight, and easy to carry;
2. Imported sealing components that do not leak;
3. Hand cranked pressurization, uniform price increase, and good constant pressure effect;
4. Both positive and negative pressures can occur. Clockwise shaking generates positive pressure, while counterclockwise shaking generates negative pressure. The operation is simple.

4、 Usage operation
The pressure output on both sides is equipped with hose connectors as standard at the factory, and the standard interface specification is M20 × 1.5 internal thread. One side is connected to the standard meter, and the other side is connected to the calibrated meter. Tighten the vent valve and when positive pressure is required, shake the rocker wheel to the opening and turn the handwheel clockwise; If negative pressure needs to occur, shake the rocking wheel to the bottom and turn the handwheel counterclockwise. Adjust the calibrated gauge by checking if the pressure value matches the standard gauge, and calibrate it using a comparative method.
