Technical Description


Adopting original excellent algorithm, achieving ms-level fast response; BLE Bluetooth communication, optional 4/5G or LoRa, 5-year maintenance-free whole machine.

Proprietary algorithm supports millisecond-level (ms) fast response; supports Bluetooth BLE communication, optional 4G/5G or LoRa technology, achieving 5-year maintenance-free operation.



Features


   TDLAS (Tunable Diode Laser Absorption Spectroscopy)

This technology provides exclusive selectivity for methane (CH4), free from interference by common gases, moisture, or dust.

   Edge terminals enhance resilience and reduce network load.

Super edge terminal integrates multi-dimensional sensing, autonomous algorithms, edge computing, storage, energy storage, encryption, and 5G/4G communication into a single unit, eliminating the need to transmit raw data to the cloud.

   Waterproof & Breathable Structural Design

Featuring a waterproof and breathable structure with fast response, high accuracy, and long lifespan. Integrated temperature compensation algorithms ensure stable performance in harsh environments and complex gas conditions.

   Innovative Multi-Parameter Integration

The Utility Tunnel Gas Monitor innovatively integrates oxygen (O₂), methane (CH₄), and hydrogen sulfide (H₂S) monitoring, ensuring gas concentrations in underground spaces remain within safe thresholds.

   Millisecond Fast Response & High Sensitivity

Proprietary algorithm enables ms-level response for reduced inspection time and ppm-level sensitivity to detect early gas leaks from valve loosening.

   Reliable Performance in Extreme Conditions

Survives harsh environments: -20°C to 80°C, high humidity, industrial wastewater, weak signals, and water immersion.

   Precise Environmental Sensing

±0.2°C temperature and ±2% RH humidity accuracy with MEMS sensor chip and waterproof breathable design, capturing subtle environmental changes.

  • How does this device ensure reliability in flooded or extreme-temperature utility tunnels?

    • It withstands ​harshest conditions​ with: ✓ ​​-20°C to 80°C​ operational range ✓ Waterproof & breathable membrane (IP68 equivalent) ✓ Corrosion resistance to industrial wastewater ✓ ±0.2°C/±2%RH accuracy despite humidity Survives full water immersion and condensation cycles.
  • Why does the 3-in-1 gas monitoring reduce maintenance needs?

    • By combining ​O₂/CH₄/H₂S detection + edge computing: ① ​TDLAS laser technology: Zero false alarms from moisture/dust ② ​On-device analytics: Processes data locally (no cloud dependency) ③ ​5-year maintenance-free operation: Sealed design + low-power components Eliminates separate sensors and monthly site visits.
