Multi-Gas Monitors
Multi-gas monitors typically feature datalogging capability, as well as audible and/or visual alarms that warn of IDLH or time-weighted average toxic gas concentrations, low oxygen levels, LEL conditions, or malfunction. These monitors may operate in passive (diffusive) mode, or in active mode, in which a pump module draws air across the sensors. Active mode speeds the response time on the meter, but care must be taken to avoid drawing particulates into the monitor. Active mode is used for remote sampling of a hazardous atmosphere: introduce the extendable wand.
Calibration gases are available from Geotech. Ensure that the calibration gas is intended for the meter make and model you are using. This is important for multi-gas use because some gases in the mixture can adversely affect other sensors in the same meter.
RAE QRAE 3Wireless 4-Gas Monitor 
QRAE 3 is a wireless compact monitor for one to four gases. The QRAE 3 provides detection and monitoring of Oxygen (O2), Combustibles, and toxic gases that include Hydrogen Sulfide (H2S), Carbon Monoxide (CO), Sulfur Dioxide (SO2) and Hydrogen Cyanide (HCN). QRAE 3 can deliver wireless real-time instrument readings and alarm status 24/7. This provides better incident visibility and can improve response time.

Honeywell BW™ Icon and Icon+ Multi-Gas Detectors
The Icon and Icon+ are multigas detectors used for personal gas detection and offer the simplest way to prioritize worker safety. Icon is named for its display of simple icons for gas levels and device status. This means there are no live gas readings for workers to interpret. Instead, when there's a gas alarm, the bell icon on the display and instrument will illuminate, and an audible alarm will alert workers to quickly clear the area.
