Introduction: Industrial waterproof telephones originated in the first half of the last century, and they flowed into China approximately in the 90s of the last century. They were mainly used in wet and high-risk operation scenarios to provide support for emergency and dispatch communications. Then a high-noise working condition dialogue machine was proposed. Anti-noise requirements.

In the world, special telephones (industrial waterproof telephones) originated in the first half of the last century, and the time of inflow into China was probably 90 years in the last century, with a batch of Japanese aid projects supporting the domestic market. The international mainstream manufacturers Gai-tronics and Germany's FHF. Domestically, Sanzhou Communications successfully developed anti-bad environment telephones in 1996 to fill domestic gaps. At the same time there are also some rising stars in Shenzhen, Ningbo and other regions.
Industrial waterproof telephones are primarily used in wet and high-risk operation scenarios to provide support for emergency and dispatch communications. After that, high-noise working conditions callers have made anti-noise requirements. With the successive launch of chemical projects, explosion-proof telephones and other derivative products have gradually emerged. After entering the new century, the development of the construction of city pipe corridors put forward higher requirements for industrial waterproof telephones, such as the detection of temperature and humidity, automatic inspection of phones, cameras, GSM, WiFi and other functions. In addition, the emergence of underground and tunnel communication scenes has also stimulated the enthusiasm of domestic manufacturers to develop new products.
The most core index protection level - IPXX (English ingress protection level)
Refer to the national standard "Enclosure protection class GB4208-2008" and apply IEC standard 60529:2001
An illustration of the waterproof rating of the tri-state lanjade is IP66
The first number represents the dustproof level, and the national standard from 0-6,6 is described as dust-proof - no dust is allowed in, ie completely dustproof - the highest dustproof level.
The second figure represents the waterproof rating, and the national standard from 0-8,6 is described as preventing violent water spray - strong impact of water in all directions has no harmful effect, ie, it is suitable for most industrial operation scenes except for explosion-proof applications.
