1.9inch clear definition color display, 240x280 resolution. Equipped with high- sensors, it monitors PM1.0, PM2.5, PM10, temperature, and humidity in real time, providing more accurate and intuitive readings. The compact body design, simple and fashionable appearance, you can put into your pocket and use wherever you want. Utilizing the newly upgraded Ammorc algorithm, the power-on test takes only 1-2 minutes, resulting in stable data, effectively reducing data fluctuations and providing more stable and faster monitoring. 0-second real-time detection and intelligent alarm. Green: Safe, no alarm sound; Yellow: When the value reaches 36ug/m³, a beeping alarm begins, cyclically every 10 minutes. Data refresh rate: 2 seconds. Hundreds of ventilation holes reserved on the housing not only accelerate the convection between the air and the machine, improve the air-flows passing rate to realize effective detection, but also provide greater heat dissipation effect. Widely applications: agricultural planting, greenhouse vegetables, production warehouse, material processing, , business offices, etc. Name: Air Quality Detector Battery: 1 x 1000mAh built-in battery (included) Display: 1.9inch color display Working voltage: 3.7V time: 35s Data refresh rate: 2s Detection ranges: 0-1000ug/m³ Operation humidity: 0-95%RH Working temperature: -20℃ to 60℃ Charging mode: Type-C interface Color: B:Black Material: ABS Package Contents: 1 x Air Quality Monitor Only the above package content, other products are not included.
