The phone is made of imported materials from Germany. The casing can withstand high temperatures and low temperatures. There will be no static on the surface of the phone. The casing has been tested for light resistance, high and low temperature resistance, heat resistance and cold resistance, etc. It has been tested for many days without failure, and the whole machine can work stably in environments ranging from sub-zero to above-zero temperatures.
1. Product Features
The outer casing is forged from imported materials from Germany. It is durable, has good sealing properties and will not cause static phone adsorption on the surface.
The display supports caller ID function or address display.
, Anti-seismic hook-free design, supports anti-vibration, and can be applied to ships, locomotives and other environments that require anti-vibration design.
, buttons Metal buttons, wear-resistant, corrosion-resistant, anti-aging, and resistant to violent damage.
The handle is made of imported materials from Germany. It has an integrated structure and good sealing performance. It will not break when hit or twisted and deformed, and will not explode at subzero temperatures.
The wire material is made of Teflon wire, which is acid and alkali resistant, high and low temperature resistant, anti-aging, and does not cause fire.
The waterproof glue adopts imported waterproof glue, which has high viscosity, high temperature resistance and high pressure resistance, and has a waterproof life of more than 10 years.
All accessories such as handle, receiver, keyboard, buzzer, circuit board, and casing adopt multi-layer waterproof and dustproof structure. It has three levels of waterproof and dustproof functions, and the whole machine level reaches the national standard/
. The phone has good stability and strong anti-interference ability, and complies with the national standard/
