Industrial Telephone non-intrinsically safe apparatus ATP-2N is a mobile terminal cooperating with any PBX CB. It is designed for use in underground mines at non-explosive methane and other mixtures, and wherever conditions are harsh work, eg. A very high humidity, noise, dust, exposure to mechanical, chemical pollution. Implemented features:
