Ex Headset for dA24

[Type iHS]

The iHS headset will keep you in safe contact even in potentially explosive environments. Thanks to the headset’s excellent insulation efficiency, you can conduct problem-free conversations even in environments with very high noise levels of up to 115 dB (A). The dynamic microphone perfectly compensates for disruptive external noises. The iHS perfectly complements the dA24 industrial telephone and is suitable for use on offshore platforms and other explosive environments
