Main Functions:
1. Provide stable positive and negative pressures for testing the air - tightness of seals or connectors.
2. The positive pressure value is digitally displayed and can be automatically controlled, while the negative pressure is controlled by a negative pressure pump.
Main Parameters:
1. Pressure gauge (-0.1 - 0.5MPa), digital pressure gauge, connecting air pipe, switch, pressure regulating valve
2. Three sets of connectors, with the diameters of the connecting pipes being 3, 5, 7 (in appropriate units) or as specified
3. Test water tank: 400mm×200mm×200mm
4. Timer: Can be set within the range of 0 - 999.9S/M/H
5. Positive pressure test: It can be pressurized according to the specified pressure, or according to the set program, such as pressurization at a level of 9.8KPa
6. Negative pressure test: Negative pressure of - 49Kpa (equipped with one negative pressure source with a maximum of - 89KPa)
7. Air source for positive pressure test: One silent compressor
