Key benefits Fast, near real-time particulate monitoring: sampling time 1.5 seconds delivers frequent updates so you can respond quickly to air quality changes. Clear, easy-to-read display: 2.8 inch LCD screen with 320 x 240 pixel resolution shows measurements and trends at a glance. Reliable PM measurement: PM detection by laser scattering provides consistent detection of airborne particles. Operates in common environments: designed to perform where atmospheric pressure ranges between 86 kPa and 106 kPa. What this product does for you Detects particulate matter quickly and reliably so you can make timely decisions about ventilation, filtration, or workplace safety. Presents data on a compact, high-resolution LCD so users can read values and trends without external devices. Works within a defined atmospheric pressure range, ensuring stable performance in typical indoor and near-ground outdoor conditions. Key attributes Display: 2.8 inch LCD, 320 x 240 pixels — compact and legible for on-device monitoring. PM detection method: laser scattering — a commonly used optical approach for particulate measurement. Sampling time: 1.5 seconds — short sampling interval for rapid updates. Operating pressure: 86 kPa to 106 kPa — suitable for standard indoor and many outdoor settings. Practical applications Home and office air-quality checks: monitor particulate levels to decide when to run air purifiers or increase ventilation. HVAC and building maintenance: perform quick spot checks near filters, ducts, and air handling units to verify particle control. On-site inspections and workshops: use the fast sampling to detect dust spikes from activities like cutting or sanding and take corrective action.
