用于检测泄漏或其它超声波源.利用超声波传感器探测气体或液体通过狭缝时所发出的超声波，从而找出泄漏处（超声波源）。

　　本仪器采用先进的超声传感技术，专门用于检测气、液等的泄漏隐患，能在现场迅速、准确、直观地找出各类压力或真空整体系统的气体、液体泄漏故障，尤其适宜检测复合材料真空成型工艺，管道阀门等部件内部产生的泄露，也能检测船舱、飞机、汽车座舱、冰箱、冷库、储油罐等密闭零件的密封程度。

　　Used to detect leaks or other ultrasonic sources. Use ultrasonic sensors to detect the ultrasonic waves emitted by gas or liquid passing through the slit to locate the leak (ultrasonic wave source).

　　The instrument adopts advanced ultrasonic sensing technology, specially used for the detection of gas, liquid and other leakage hazards, can quickly, accurately and intuitively find out all kinds of pressure or vacuum system of gas, liquid leakage faults, especially suitable for the detection of composite material vacuum forming process, pipe valves and other parts of the internal leakage, It can also detect the sealing degree of airtight parts such as cabin, airplane, automobile cabin, refrigerator, cold storage and oil tank.
