Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Gas Leak Detection & Alarm: Equipped with an 8-channel LCD digital controller, the system detects gas leaks in real-time (0-5000ppm) and triggers audible/visual alarms for immediate alerts.
  • Automatic Shut-off & Control: Features a gas shut-off valve and relay output to automatically halt gas supply and control external devices (e.g., fans, ventilation systems) upon detecting hazardous concentrations.
  • Multi-Range Monitoring: Supports customizable measurement ranges (0-100ppm, 0-1000ppm, or 0-5000ppm) to suit varying environmental conditions and gas types.

Key features

  • 1. Explosion-Proof Material Technology

    • With explosion-proof materials in the axial flow fan and gas shut-off valve, ensure safe operation in hazardous environments prone to flammable gas leaks. This design meets stringent safety standards, offering ~30% higher durability than non-certified systems*.

  • 2. 8-Channel Digital Interactive Design

    • With an LCD digital display and multi-channel gas monitoring, track gas concentrations across eight sensors simultaneously. This real-time visibility enhances situational awareness compared to single-channel systems, reducing response delays*.

  • 3. Broad Performance Range

    • With a measurement range of 0–5000ppm (expandable to 0–1000ppm), detect gas leaks across diverse scenarios, including high-concentration industrial environments. This 5x broader range than standard models enables adaptability for varied applications*.

  • 4. Automatic Shut-Off & Continuous Monitoring

    • With an integrated gas shut-off valve and continuous monitoring capability, prevent disasters in commercial kitchens or industrial plants by automatically halting gas flow upon detection. This feature reduces operational downtime by up to 40% during emergencies*.

  • 5. Certified Safety Compliance

    • Complying with international safety standards (e.g., ATEX/IECEx), the system ensures reliability in certified hazardous zones. This certification guarantees adherence to rigorous explosion-proof and environmental protection protocols*.

Supplier's note

  1. Technical Breakthroughs:

    • Explosion-Proof Design: Meets IECEx standards, enabling deployment in volatile zones like oil refineries.
    • Extended Detection Range: The Pro model’s 0-5000ppm capability covers industrial gases like ammonia or hydrogen sulfide.
    • Automatic Shut-off Valve: Reduces fire/explosion risks by cutting gas supply within 2 seconds of leak detection.

  2. Version Selection Guidance:

    • Base Model: Ideal for low-risk environments (e.g., commercial kitchens) needing basic CO detection.
    • Advanced Model: Suitable for manufacturing plants requiring mid-range gas monitoring (e.g., solvents) with 6-channel control.
    • Pro Model: Recommended for chemical facilities handling toxic gases, where triple-certified safety and 8-channel precision are critical.

With the Pro’s IECEx certification, you can safely deploy it in offshore platforms, while its 0-5000ppm range paired with 10-second response time ensures rapid intervention. The Advanced Model’s ATEX compliance and 6 channels make it perfect for automotive paint shops needing moderate-range monitoring.
