Gas detector-four in one
Applicable to multi gas detection
For HAZMAT response and aftergases detection
ISO9001 certificate
Gas detector – four in one multiple gas detector
Features
• Fully functional self-testing: sensor, integrity of battery and circuit, acoustic & visual & vibration three-stage alarm.
• Real-time detection for the concentration of hydrogen sulfide (H2S), carbon monoxide (CO), sulfur dioxide (SO2), oxygen (O2) and combustible gas.
• Gas Alert Micro series have a wide application, including HAZMAT response, enclosure space entry and post fire inspection.
• The deadline date and alarm threshold can be adjusted based on the request in special industry.
• Password protection capability: only the authorized user can modify the preset parameter.
• It is the primary inspection tool with high performance-price ratio and multiple functions in the field of multiple gas detecting.
• TWA (time weighted average) alarm and STEL (short-term exposure limit) alarm is applicable to H2S and CO; OL (over limit) alarm is applicable to combustible gas.
• Keep record of TWA, STEL and peak value of gas composition for display when needed.

Attentions
• The transducers have high resistance to common steam and gas.
• The transducers will start self-cleaning if move the detector to clean environment and wait for 10~30 min.
• Be sure not to expose the transducer to inorganic solvent steam (such as paint gas) and organic solvent.
• Do not test the response of combustible gas transducer by a liquid cigarette lighter, or the transducer will be damaged.
• Please set the detector when first applied, the next adjustment can be confirmed based on the exposure duration of transducer in the toxic gas (recommended frequency is semiyearly).
