Supplier's note

  1. Three Breakthroughs:

    • Multi-Sensor Fusion: Combines galvanic, electrochemical, and catalytic sensors for unmatched accuracy across gas types.
    • Rugged Design: Durable plastic housing withstands extreme temperatures (-20°C to 50°C), ideal for harsh industrial settings.
    • Customizable Alarms: Voice alerts and vibration modes ensure alerts are never missed in noisy environments.

  2. Version Selection Guide:

    • Base Model: Suitable for occasional use (e.g., small construction crews) needing basic gas monitoring.
    • Advanced Model: Optimal for frequent users (e.g., industrial inspectors) requiring extended battery life and voice alerts.
    • Pro Model: Designed for corrosive or high-risk environments (e.g., chemical plants), with triple the chemical resistance and 24-hour runtime.

With the Pro’s 5-second response time and triple chemical resistance, you can safely handle volatile gases like H₂S in refineries. Pair this with its vibration alerts to ensure compliance even in loud machinery zones.
