Portable LED Display PM2.5 Detector Multifunctional Temperature and Humidity Test Meter Laser multicolour

About this item

• This portable air quality tester adopts a laser particle sensor and a high-precise optical sensor, with stable performance and high detection accuracy, supporting real-time monitoring of PM2.5 concentration, temperature, and relative humidity in the air. Digital LED display, with ultra-wide viewing angle, so you can see the readings at a glance. 3D porous housing with multiple ventilation holes designed for real-time air circulation convection. The sensor and theair are fully contacted, highly sensitive, and accurate in the detection of small particle content. It can be widely used in a variety of occasions. Features: Compact and Exquisite: Compact body design, simple and stylish appearance, lightweight, and easy to carry. 3D porous housing with multiple ventilation holes designed for real-time air circulation convection. The sensor and theair are fully contacted, highly sensitive, and accurate in the detection of small particle content. PM2.5 Concentration & Temperature & Humidity Measurement: Built-in nice-performance laser particle sensor and a high-precise optical sensor to real-time detect the PM2.5 concentration, temperature and humidity data at the same time, to ensure obtained accurate data easily in harsh environments. PM2.5 particle sensor is more accurate than infrared sensor, comes with a fan to increase gasflow and increase the detection scope and sensitivity, with fast computing speed, and the detection results are more accurate. Digital LED Display: Digital LED display, with ultra-wide viewing angle, so you can see the readings at a glance. With automatic brightness adjustment function, according to the surrounding brightness, automatically adjust the screen display brightness, so that the screen is visible and not harsh.  Energy Saving Screen Off &  Hand Waving Wake-up: When no one is using the screen, it can automatically turn off the screen to reduce power consumption, and the sensor can still transmit data to the cloud via WIFI in the screen off state so that you can view the real-time values through the APP. Supports waking up the screen by waving your hand at the sensing distance. Intelligent Sound & Light Alarm System: Real-time monitoring of PM2.5 content in the environment, when the PM2.5 concentration reaches 25μgm³, it will promote the sound alarm. The color changes according to the PM2.5 concentration, 0-20μgm³ concentration green block flash, 20-25μgm³ yellow block flash, 25-50μgm³ orange block flash, 50-75μgm³ red block flash, more than 75μgm³ four blocks flash. WiFi Connection & Mobilephone APP Control: Built-in WIFI for cloud link, real-time update air quality data through mobilephone APP, users can check the air quality data anytime, anywhere, allowing users to keep track of the air condition in their home and remind their family to purify the air. Wide Applications: Adopting 800mAh high capacity polymerized lithium battery, Type-C charging port, with long-lasting endurance, suitable for a variety of complex environments. It can be widely used in a variety of occasions, such as homes, greenhouses, camping barbecues, factories, automobiles, environmental monitoring, and so on.
