2.8-inch colour LCD (320 x 240 pixels) O3 detector with adjustable alarm and active air sampling Key benefits Immediate awareness: Built-in O3 alarm with user-adjustable threshold notifies you when ozone concentrations rise, so you can act before levels become problematic. More reliable readings: An integrated fan actively draws ambient air into the sensor for faster, more representative, real‑time measurements than passive sampling. Clear, easy-to-read display: The 2.8-inch colour LCD (320 x 240) shows readings and alarm status at a glance, reducing interpretation time and improving operator confidence. What it does for you Protects occupants and equipment by detecting elevated ozone concentrations and alerting staff. Verifies air quality after disinfection processes to ensure residual ozone levels are within acceptable limits. Provides continuous, real‑time monitoring to support routine checks and incident response. Important attributes Function: Real-time ozone (O3) detection with adjustable alarm threshold. Display size and resolution: 2.8-inch colour liquid crystal display (LCD), 320 x 240 pixels for clear numeric and status readouts. Sampling method: Integrated fan actively draws ambient air for faster, more accurate measurements. Performance: User-set alarm threshold enables customization for different environments and safety requirements. Practical use scenarios Offices and rest zones: Monitor common areas and break rooms to ensure occupant safety and maintain comfortable indoor air quality. Post-disinfection checks: Confirm residual ozone levels after ozonation or other disinfection procedures before re‑occupying spaces. Indoor and outdoor spot checks: Use for site surveys or spot monitoring where immediate indication of elevated O3 concentrations is needed. Why choose this unit Simple, adjustable alarm settings and a readable colour display make this detector practical for facilities staff, safety officers, and service technicians who need dependable, real‑time ozone information without complex setup.
