Detail：

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.

Model：MT-618S

Product Features:

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.
