BW GasAlert Micro 5 Detector
BW GasAlert Micro 5 Detector providing protection from up to five potential atmospheric hazards including oxygen, combustible and toxic gases, the BW GasAlert Micro 5 is unparalleled in its versatility, capability and overall value. The Honeywell BW Micro 5 portable gas detector has transformed the market with its matchless array of features.
Continuously monitoring and displaying concentrations of up to five gases, the compact and lightweight GasAlertMicro 5 was designed and engineered with an extensive host of applications in mind.
Detectable Gases
- Monitors H2S, CO, O2, SO2, PH3, CI2, NH3, NO2, HCN, CIO2, O3 and combustibles
- Water-resistant

Compact and lightweight, BW GasAlert Micro 5 Series instruments are available in diffusion or pumped versions. The portable gas detectors simultaneously monitors and displays up to five potential atmospheric hazards. The GasAlert Micro 5 PID model also identifies PID detectable VOCs, while the GasAlert Micro 5 IR uses an NDIR sensor to monitor CO2 levels.
Adaptable to a variety of applications, Honeywell GasAlert Micro 5 detectors have an extensive selection of user-settable field options. Use the passcode function to prevent unauthorized modifications of the instrument’s settings. Compatible with BW’s MicroDock II automatic test and calibration system, GasAlertMicro 5 Series instruments are unparalleled in their versatility, performance and overall value.
