Based on the original telephone production,Miran developed and produced the MT-618S embedded stainless steel clean room telephone for the pharmaceutical, chemical,electronic and food clean workshops.The main circuit is controlled by industrial grade ATML single-chip microcomputer.The performance is stable,the degree of intelligence is high,and the program can be upgraded.
1.Stainless steel panel and shell, the surface is completely flat, strong impact resistance. Made of 304 stainless steel, beautiful appearance;
2.All the accessories of the receiver, button, buzzer, circuit board and outer casing are designed with multi-layer waterproof and dustproof structure;
3.The phone has good stability and strong anti-interference ability;
4.Embedded installation, designed for clean room installation;
5.The outer casing has a grounding device and is completely electrically isolated from the internal circuit, and has a certain electromagnetic shielding effect;
6.The voice is clear when the call is made, the sound is loud, and there is no feedback whistling.
