The Honeywell BW ICON+ multi-gas monitor delivers an icon-based experience in a serviceable package. It enables you to maximize the lifespan of your four-gas detectors, optimize long-term cost of ownership and select from multiple gas sensors for flexible applications. The Icon+ is named for its first in-the-industry display of simple icons for gas levels and device status. No live gas readings for workers to interpret and no time-consuming training. When there's a gas alarm, the bell icon on the display will illuminate, along with an indicator next to the sensor in alarm, so workers can quickly clear the area.
