Product Description

Mine Explosion-Proof VHF portable interphone

Application
This product uses computer chips, with software modulation and programming functions, adding 15 adjustable channels. Working in 144MHz ~ 166MHz frequency band, the transmitting power can be adjusted from 0.3W to 1.2W. The sensitivity of receiving is higher. It has the function of anti-interference of mute audio, which makes the communication effect clearer and the working performance more stable, safe and reliable. Handheld station is an extension of mine leakage communication system, which is used by underground mobile personnel.
