product details
Zhongan S400 is an intelligent multifunctional gas detection instrument, which can be combined with four in one or five in one for different gases. The instrument adopts high-performance detection components and computer micro control technology, combined with advanced fully automatic mounting technology. The product has functions such as on-site buzzing indicator sound, on-site flashing indicator light, and real-time display and monitoring of on-site gas concentration.
The Zhong'an S400 multifunctional point type gas detector can convert gas concentration signals in the air into electrical signals for display and remote transmission. It adopts a two bus or four bus RS485 output mode and has the characteristics of long transmission distance and good anti-interference performance.
The Zhong'an S400 point type gas detector can be used in industrial environments that require explosion prevention, poisoning prevention, and suffocation prevention, such as chemical plants, smelting and papermaking, refrigeration and firefighting, gas catering, rubber, sewage treatment, pharmaceutical casting, petroleum refining, mining and power, fire and municipal engineering, communication, etc.
