PID principle of factory VOCS exhaust gas online monitoring instrument display system
PID principle of factory VOCS exhaust gas online monitoring instrument display system
Product details
The BYG488-VOCS factory VOCS exhaust gas online monitoring instrument display system continuously detects TVOC gas in the environment and displays it online with a matching LED screen. It not only controls the gas concentration in special occasions, but also has a warning effect on gas leaks in dangerous sites, timely protecting the safety of life and property on various sites. The BYG480-VOCs organic volatile gas detector adopts imported electrochemical or PID principle sensors combined with high-speed and high-precision processing circuits, which have the advantages of stable signal, high accuracy, and good repeatability. It also adopts explosion-proof design and is suitable for various hazardous occasions. The instrument outputs various standard signals and is compatible with various alarm systems, PLC, DCS and other control systems.
