Fast, reliable detection of airborne particles in just 3 seconds Laserdust sensor immediately detects surrounding harmful airborne substances, giving you quick awareness of dangerous particle levels so you can act fast. Accurate PM2.5 measurement with sensitivity Builtin PM2.5 sensor delivers consistent, sensitive readings to track fine particulate matter that affects health, helping you make informed ventilation or filtration decisions. Reduced false readings through antiinterference design Superantiinterference architecture and detection amplification provide more accurate results in environments with variable airflows or background signals, so measurements remain dependable. Representative multidirectional sampling, test anytime Multidirectional air testing samples air from different angles to produce a more representative measurement of room conditions, and supports testing at any time for convenient spot checks. Key benefits at a glance Rapid response: 3second detection reduces the delay between exposure and awareness. Trusted measurements: sensitivity PM2.5 sensing and consistency ensure useful data for healthrelated decisions. Reliable performance: Antiinterference design minimizes noise and improves result accuracy. Practical placement: Multidirectional sampling gives a clearer picture of realworld air conditions. Practical use scenarios Home: Monitor kitchen, living room, or bedroom air after cooking, smoking, or during outdoor pollution to know when to ventilate or run an air purifier. Office and shared spaces: Spotcheck work areas to ensure a healthier environment for employees and visitors, detect sudden pollution sources, and validate HVAC performance. Childcare and sensitive environments: Quickly detect elevated PM2.5 or dust levels in nurseries, classrooms, or elderly care areas to protect vulnerable occupants. Performancefocused functionality Combines a laserdust sensor and a sensitivity PM2.5 sensor to detect fine particles and harmful substances. Antiinterference detection amplification enhances measurement stability and accuracy. Multidirectional testing provides more representative air sampling and supports testing at any time.
