Clean room dedicated telephone, pharmaceutical factory telephone

Clean room-specific telephones are no longer a new term. They are now gradually being recognized by relevant persons in charge of domestic pharmaceutical companies. As the renovation and expansion projects of clean factories are carried out, products are increasingly appearing in clean rooms of uneven sizes, bringing great benefits to pharmaceutical workshop staff. Convenient communication Zhenxi Jun Technology Co., Ltd. launched a stainless steel clean room telephone, breaking the monopoly of similar foreign products in one fell swoop and creating the first high-end clean room communication product in China. It is the first choice product for China's pharmaceutical purification workshops
, product features
1. Except for the internal circuit board, the entire machine is made of stainless steel and the surface is brushed
2. All openings and edge cuts are made by non-marking laser cutting
3. The surface is completely smooth. No uneven feeling
4. The surface is waterproof and dustproof, with a built-in waterproof speaker
5. The stainless steel material is acid and alkali resistant and has strong chemical corrosion resistance. Various cleaning agents can be used for surface cleaning
6 , Hands-free design to avoid cross-contamination
7. The built-in circuit of the phone has strong anti-interference ability, and the call sound quality is stable and clear
8. For individual workshops that require strong anti-noise ability, an external power supply solution can be customized to improve Decibel rate
, Scope of application
This type of embedded hands-free telephone is developed for clean rooms, biopharmaceutical factory workshops, dust-free rooms, elevators, etc. The main circuit is controlled by an industrial-grade microcontroller, with stable performance, high intelligence, and program upgradeability.
