KTK18(A) intrinsically safe amplifying telephone for mining useDetailed product description：

The KTK18 (A) intrinsically safe amplifying telephone for mining is mainly used in the area of underground tapping and communication. When multiple (usually more than 10) amplifying telephones are used in combination, to prevent signal attenuation, an additional device is added to amplify the input signal before transmission, expanding the transmission distance.
