Key benefits See the full picture of indoor air quality at a glance: monitors PM5, PM1.0, PM10, CO, TVOC and HCHO while displaying current date and time so you can make timely ventilation or cleaning decisions. Reduce health risks and nuisance symptoms by identifying particulate and gaseous pollutants quickly; use real-time readings to adjust cooking, cleaning, or HVAC settings. Portable, easy to use and syncs with your smartphone for continuous updates and remote monitoring. What this device does Multi-pollutant sensing: reports fine and coarse particulates (PM1.0, PM5, PM10) plus carbon monoxide (CO), total volatile organic compounds (TVOC) and formaldehyde (HCHO). Clear, multifunctional display: shows date and time, supports a vertical screen mode for a clock-style view, and includes a stopwatch function for timed checks. Smartphone sync: provides real-time data updates to your phone so you can track trends, receive current readings and keep records. Practical advantages Fast problem detection: spot spikes from cooking, cleaning products or nearby construction and take action to reduce exposure. Portable and versatile: compact design makes it simple to move between rooms, carry to a restaurant, office, or hotel room, and place on countertops or shelves. User-friendly controls and display options help you monitor continuously or perform short, targeted measurements with the stopwatch mode. Compatibility, size and performance notes Designed for everyday indoor use in homes, restaurants and similar settings. Compact, portable form factor for convenient placement and transport. Real-time smartphone synchronization keeps data current and accessible when you need it. Use scenarios Home bedroom: monitor PM and gas levels overnight and verify that ventilation or an air purifier is effectively lowering pollutants while you sleep. Restaurant or kitchen: spot-test air quality during meal prep and cooking to detect spikes in particulates or VOCs and protect staff and customers. Travel or office checks: carry the device to assess air quality in hotel rooms, meeting spaces or temporary work areas before extended occupancy. What you’ll get Continuous measurement of PM5, PM1.0, PM10, CO, TVOC and HCHO. Date/time display with vertical screen and stopwatch modes for flexible monitoring. Portable design and smartphone sync for real-time data access and easy spot checks. Simple, dependable monitoring to help you identify indoor air issues quickly and take practical steps to improve air quality.
