Beschrijving
De GDS 404 is ontworpen met kenmerken die een effectieve reactie op de detectie van gevaarlijke gassen in een breed scala van omgevingen van kantoorpanden tot zware industriële toepassingen waarbij gevaarlijke stoffen aanwezig zijn.
Typische plaatsen voor de monitor zijn openbare gebouwen, boilers, zwembaden, waterzuiveringsinstallaties, H & V controlesystemen en bij de productie en verwerking van planten.
