Product introduction
Miran has independently developed and produced MT-618S embedded stainless steel cleanroom telephones for pharmaceutical, chemical, electronic, and food cleanroom workshops based on its original telephone production. The main circuit is controlled by an industrial grade ATML micro-controller, which has stable performance, high intelligence, and upgradable programs.
Model: MT-618S
Product Features:
1) Stainless steel panel and shell, with a completely flat surface and strong impact resistance. Made entirely of 304 stainless steel, with a beautiful appearance;
2) The receiver, buttons, buzzer, circuit board, and all accessories of the casing are designed with a multi-layer waterproof and dust-proof structure;
3) The phone has good stability and strong anti-interference ability;
4) Embedded installation, specifically designed for cleanroom installation;
5) The shell has a grounding device and is completely isolated from the internal circuit, providing a certain electromagnetic shielding effect;
6) During the call, the voice is clear, the sound is loud, and there is no feedback whistling
