Wearable Diffusion Multi Gas Monitor with IP66/IP68 Waterproof 24h Battery and Man Down Alarm

MicMeta is a professional, compact and wearable multi-gas detector certified with IECEx, ATEX and EMC. It adopts diffusion sampling type to simultaneously detect carbon monoxide (CO), hydrogen sulfide (H2S), oxygen (O2) and flammable gas (LEL). With explosion-proof, waterproof, drop-resistant and man-down alarm design, it is widely used in coal mines, petroleum, chemical industry, metallurgy, confined spaces and other high-risk industrial environments to ensure personnel safety.

MicMeta is a lightweight, high-reliability multi-gas detection device designed for harsh industrial environments. It adopts diffusion detection method, standard configuration for CO, H2S, O2, LEL four kinds of gases, and also supports hundreds of kinds of gas customization.

The whole machine has IP66/IP68 protection grade and 1.5 meters drop resistance, with stable performance and strong durability. It is equipped with standard man-down alarm, data recording, self-inspection and password protection functions. Optional Bluetooth and Lora wireless transmission are available to realize remote data viewing and management. It can be equipped with a special docking station for fast calibration and bump test, which is convenient for daily maintenance.

It has complete explosion-proof certification and is suitable for flammable and explosive places such as coal mines, oil fields, chemical plants and shipyards.

The MicMeta diffusion gas detector is widely used in industries where workers face potential exposure to toxic gases, oxygen deficiency, or combustible hazards. Key application environments include:

1. Coal Mining
   • Continuous monitoring of methane (LEL), CO from blasting or diesel equipment, H2S from certain seams, and O2 levels in return airways.
   • Man down alarm is critical for lone miners working in longwall faces or maintenance tunnels.
2. Petrochemical & Oil Refineries
   • Personal protection during turnaround maintenance, tank cleaning, and pipeline inspection.
   • Diffusion design allows hands-free monitoring while operators climb ladders or use both hands for tools.
3. Confined Space Entry
   • Ideal for pre-entry checks and continuous wear inside tanks, silos, sewers, vaults, and storage vessels.
   • IP68 rating ensures operation even if submerged in water or sludge.
4. Natural Gas & LPG Handling
   • Detects LEL for methane/propane leaks in compressor stations, metering rooms, and distribution networks.
5. Fire & Rescue
   • Worn after fire suppression to check for lingering CO or oxygen deficiency in burned structures.

• International certifications – Fully compliant with IECEx, ATEX, and EMC for global use in explosive atmospheres.
• Rugged design expertise – Engineered for extreme dust, water, and drop conditions (IP66/IP68, 1.5m drop).
• Flexible gas configuration – Standard 4-in-1 plus hundreds of other gas options to meet diverse markets.
• Wireless-ready platform – Optional LoRa/Bluetooth for IoT integration and remote monitoring.
• Fast support – Remote firmware upgrades, docking station for easy field calibration, and global certification documentation.
• Quality assurance – Manufactured under strict quality control with automatic self-test on every power-up.
