Core Technical Parameters of Intelligent Fume Hood | Intelligent Wet Process Workstation

Fume hoods are essential laboratory equipment. Traditional fume hoods have single functions and fixed operation modes, running passively after installation and startup. Intelligent fume hoods are upgraded versions of traditional ones. For example, Hualing Kena Intelligent Wet Process Workstation (Intelligent Fume Hood) adds functions such as intelligent voice control, intelligent early warning, infrared sensor door interlock, sash height control, online gas monitoring, and modular structure design on the basis of traditional fume hoods.
