Ø It uses ESR environmental sound target recognition technology and the sound source 

positioning technology based on beam-forming theory to measure the location of the sound emitted by the equipment and the state of sound radiation. 

Ø It covers the entire range from the audible sound band to the ultrasonic band and visualizes the collected sound in the form of a color contour map, effectively measuring the sound field distribution. 

Ø The device can not only detect gas leaks and partial discharges, but also expand functional detection, including infrared thermal imaging detection, internal leakage detection or other detection functions.

Ø It is designed with fill light for low-light environment detection and has an external sensor function.

Ø The body is made of aluminum alloy to increase the durability of the device.
