CRY710 Pneumatic Acoustic Test Chamber

The CRY710 Pneumatic Shielding Box, constructed from welded steel plates, provides robust RF shielding for testing Bluetooth, Wi-Fi, and other devices, effectively preventing interference between production lines. It also offers a soundproof environment for assessing acoustic performance. The pneumatic door can be controlled via the serial port.

‍For quadruplex audio testing of TWS headphones, combining two CRY710 boxes with a CRY6151B enables a single operator to manage two test stations simultaneously, significantly reducing labor costs.
