Stainless steel cleanroom telephones are mainly developed as embedded hands-free telephones for cleanrooms, biopharmaceutical workshops, clean rooms, elevators, and other applications. The main circuit is controlled by an industrial grade ATML microcontroller, which has stable performance, high intelligence, and upgradable programs.

Stainless steel cleanroom telephones mainly have the following characteristics:

1. Except for the internal circuit board, the entire machine is made of 304 stainless steel The surface of the phone is treated with wire drawing

2. All openings and edges are cut using laser cutting;

3. The surface is smooth and flat, without any unevenness;

4. The surface has waterproof and dustproof functions, with built-in waterproof speakers;

5. Stainless steel material is resistant to acid and alkali, and has strong chemical corrosion resistance. It can be cleaned with various cleaning agents on the surface;

6. Hands free design to avoid cross contamination;

7. The built-in circuit of the phone has strong anti-interference ability, and the sound quality of the call is stable and clear;

8. The product has an external power supply to increase the decibel level If there is really no power supply, it can be adjusted to not use a power supply through the main switch.
