Five-Gas Detector: H₂S, CO, O₂, SO₂, PH₃, NH₃, NO₂, HCN, Cl₂, ClO₂, O₃ and Combustibles

• Continuous LCD shows simultaneous gas concentrations for five gases
• Smaller and over 50% lighter than competitive instruments
• Water-resistant design with an integral concussionproof enclosure
• Integral motorized pump option for remote sampling
• Two power options: AA alkaline or rechargeable hotswappable battery packs
• Provides 95 dB alarm tone and two bright wideangled alarm bars
• Equipped with internal vibrating alarm for high noise areas
• Multi-language support in English, French, German, Spanish and Portuguese
• Three backlight options: standard—activates in low light (auto), in alarm (auto) and reactivates ondemand; alarm only—activates in alarm conditions and reactivates on-demand; stealth mode— deactivated
• Four alarm levels: instantaneous Low and High Alarm for all gases;
• TWA (time-weighted average) and STEL (short-term exposure limit) for toxic gases
• Simple automatic calibration procedure; compatible with BW MicroDock II automatic test and calibration station
• Records TWA, STEL and maximum exposures to gas and displays readings on command
• User selectable field options include: language selection, confidence beep, span level, set TWA/STEL calculation choice, set calibration due date, passcode protection, latching alarm,
• "SAFE" display function, stealth mode and selectable ppm resolution for some gases (e.g. SO₂ 0.1 ppm)
• Full function self-test of: sensor, battery and circuit integrity; and audible/visual alarms

GasAlertMicro 5 portable gas detector simultaneously monitors and displays up to five potential atmospheric hazards including oxygen, combustible gases and a range of toxic gases. Compact and lightweight, GasAlertMicro 5 adds multigas detection to BW Technologies’ water resistant line of detectors. Audible, visual and vibrator alarms activate in the event of a low, high, TWA or STEL alarm condition. An optional motorized pump is available.

Beyond features that come standard with BW portable instruments such as confidence beep, full function self-test, automatic calibration and passcode protection, GasAlertMicro 5 offers an extended selection of user-settable field options now including: stealth mode, backlight options, selectable ppm resolution, STEL / TWA measurement choice, combustible correction factor options, usersettable calibration gas concentrations and multi-language support.
