XOS240 features rubber feet and mounting holes for the bracket, allowing it to be placed independently on a horizontal surface or fixed to a dedicated bracket through the mounting holes. Additionally, it is equipped with a stainless-steel handle for the convenient transportation and carrying of the sound source. Compared with ordinary omnidirectional sound sources, XOS240 can provide higher frequency non-directional sound signals. The directional index is ≤ ±3 dB in the frequency range of 2 kHz to 40 kHz, and the directional index is ≤ ±2dB below 5 kHz. 

Features:

      ● It is composed of professional ultrasonic units and is suitable for high-frequency measurements ranging from 2 kHz to 40 kHz

      ● The 12-sides design and low directivity index ensure high-quality acoustic performance

      ● Small in size, light in weight, easy to carry

Applications:

      ● Non-destructive detection and location of leakage points in doors, windows, and enclosed spaces

      ● Other high-frequency acoustic measurements of buildings

Other features/parameters/pictures of XOS240 are as follows：

1.The typical frequency response graph of the sound pressure level at 1 meter (pink noise, BSWA PA300).

2.The directional index graph

The dashed line is the limit value, and the solid line is the maximum positive deviation and maximum negative deviation measured.

3.Horizontal directivity diagram

the measuring point is 1.5 meters away from the center of the sphere, and the noise radiation is basically the same in all directions below 5000Hz.
