Portable Multi Gas Detector CO O2 H2S CH4 Detected With Diffusion High Precision

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Multi-Gas Detection: Simultaneously monitors carbon monoxide (CO), hydrogen sulfide (H2S), oxygen (O2), and flammable gases (CH4) via diffusion for real-time environmental safety assessment.
  • Precision Measurement: Offers high accuracy across gas ranges (e.g., 1% LEL for flammable gases, 0.01 ppm resolution for H2S) to ensure reliable readings in critical scenarios.

Key features

  • 1. Rugged Material Technology for Harsh Environments

    • With its corrosion-resistant, ergonomic design featuring a durable plastic/rubber grip and textured surfaces, you can operate reliably in industrial or outdoor settings where traditional detectors may degrade faster. ~30% more resistant to impacts and abrasions than standard models*

  • 2. Multi-Gas Interactive Display for Clear Monitoring

    • With a high-visibility digital screen and intuitive button controls, you can simultaneously track four critical gases (CO, H₂S, O₂, and flammable gases) in real-time, unlike single-gas detectors that limit your safety coverage.

  • 3. Precision Accuracy for Early Hazard Detection

    • With sub-ppm sensitivity (0.01ppm for H₂S) and 1% LEL accuracy for flammable gases, you can detect threats at levels 50% finer than conventional models*, ensuring proactive protection in hazardous scenarios.

  • 4. Versatile Scenario Solutions for Diverse Applications

    • With portability and multi-gas detection capability, you can safeguard homes, industrial sites, or environmental monitoring zones, offering broader utility than non-portable or single-function devices.

  • 5. CE-Certified Safety Compliance

    • With CE certification, you can trust compliance with EU safety and performance standards, ensuring reliability where uncertified alternatives may pose regulatory or operational risks.

Supplier's note

  1. Technical Breakthroughs:

    • Pro Model’s H₂S Sensitivity: 0.001ppm accuracy (90% better than Base) enables early detection in confined spaces.
    • Advanced’s Extended CH₄ Range: 0-200%LEL coverage meets oil/gas industry demands for broader hazard detection.
    • Rugged IP68 Rating: All models withstand water/dust ingress, critical for construction and mining.

  2. Version Selection Guide:

    • Base Model: Ideal for general industrial use (e.g., warehouses) where standard compliance (CE) suffices.
    • Advanced Model: Suitable for hazardous zones (e.g., oil refineries) needing ATEX certification and faster response times.
    • Pro Model: Best for extreme environments (e.g., chemical plants) requiring ultra-precise H₂S detection and IECEx compliance.

With the Pro’s triple-certified ruggedness, you can safely monitor explosive gases in offshore platforms. Pair its 0.001ppm H₂S sensitivity with IP68 protection to ensure zero downtime in corrosive conditions.
