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.
