8 channels pressure test analyzer is mainly used for the performance test of main pump,sub-pump,door pump,quick release valve,4 loops and etc. in braking system of big bus and medium/heavy truck.It can be used as the testing equipment in automobile repair,and is especially suitable for repairing and testing the air circuit of city bus and heavy truck.It can record the pressure curve of each testing point in the braking process in real time.,such as the pressure curve of main pump,main vehicle relay valve,trailer valve and three bridge emergency brake valve,so we can judge if the pump valve in the vehicle is in fault condition,if the air circuit of brake is blocked,and if the distribution of braking force of the main trailer is reasonable.

The air circuit test of big bus and medium/heavy truck:

• Test range: main pump,main vehicle relay valve,trailer valve and three bridge emergency brake valve,regulating valve.
• Suitable for the test of working performance and working condition of main pump valve,sub-pump chamber,quick release valve four circuits,various pump valves and orther devices in automobile brake system.
• Main pump valve: air cylinder inflates the relay valve through main pump valve,test the time and if there is a leakage.
• Four circuits:the test of leakage and the test of air pressure fault of switch
• Sub-pump:the test of inflation time of single/double cavity and leakage.
• Relay valve:the test of leakage,inflation and exhaust time.
• Quick release valve: air cylinder passes through quickly release to sub-pump, test its air pressure saturation time and leakage.
• Smaller volume,portable,suitable for debugging and repairing in the scence.
• Charged by laptop,no external power required.
• Standard epuipped brake pedal switch,record the starting point of braking precisely.
• Standard equipped multi-fuction diagnosis adapter,can test air circuit of most of buses and medium/heavy trucks through combinations of various types of adapters.
• Standared equipped common-use size test hose,the internal thread of which is M16*1.5.
• It can record 7 circuits of pressure signal and 1 circuit of brake pedal signal in real time and collect them synchronously.
• It is flexible in parameter setting,the name,curve color and thickness of each channel’s signal can be customized.
• Adding to self-correcting function,it can ensure the measurement accuracy of different sizes of air pressure sensors.
• Equipped high accuracy air pressure sensor,the mobile measurement can be accurate.
• Support replaying the record and printing the test report.
