Product Introduction:
YSS400 gas detector is aIntelligent multifunctional gas detection instrumentThe instrument adopts high-performance detection components and computer micro control technology detectors, combined with advanced fully automatic mounting technology manufacturing. The product has functions such as on-site buzzing indicator sound, on-site flashing indicator light, and real-time display of gas concentration detectors monitoring the site.
The YSS400 multifunctional point type gas detector can convert gas concentration signals in the air into electrical signals for display and remote transmission. It adopts two-wire RS3082, three wire 4-20mA or four bus RS485 output methods, and has the characteristics of long transmission distance and good anti-interference performance.
The YSS400 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.
