CT-PTT / ASR-Communication ATEX — headset PTT set with hearing protection (CeoTronics)

The ATEX version of CT-PTT / ASR-Communication is an intrinsically safe CeoTronics headset communication set with high-attenuation earmuffs and a noise-cancelling microphone. The ASR option provides level-controlled ambient listening — protecting hearing while still letting the user hear commands and signals. ATEX certification (Ex ib IIB/IIC T4) permits work in potentially explosive atmospheres.

Note: We select the microphone version (electret/dynamic/laryngophone) and the radio connector type to suit the application.
