3-IN-1 Air Quality Monitor,GR-5800S HCHO/TVOC detector with PM2.5 Particle Counter,Multifunctional Air Gas Detector with Big LCD Air Quality Sensor Analyzer with Real Time, Data Record for Home Office

• Multifunctional Air Quality Monitor: The upgraded indoor air quality monitor can accurately detect formaldehyde (HCHO), volatile organic compounds (TVOC), and particulate matter (PM2.5/PM10) in the air. The detector is highly sensitive to formaldehyde, benzene, harmful chemicals and pollutants, such as carbon monoxide, cigarette smoke, fog, dust, alcohol, etc. It is a good helper for testing air quality.
• High Precision and Fast Response: The air quality meter is developed by using laser PM2.5 sensor, electrochemical formaldehyde sensor, thick film semiconductor gas sensor, TVOC sensor and single-chip technology. The high sensitivity sensor not only allows you to obtain accurate readings within 30 seconds, but also enables the air quality detector to have higher accuracy. PM2.5/PM10 resolution: 0.1 μ g/m³; TVOC resolution: 0.05mg/m³; Formaldehyde resolution: 0.01mg/m³.
• Rechargeable Battery: GOYERRNES air quality detector is equipped with 2000mAh rechargeable battery and USB cable. The maximum working time can reach about 15 hours. With backlight LCD display and low battery indicator. Auto off/power mode saves battery power. Do not use it when charging or using low battery, because the data may not be accurate.
• Color LCD and Audible Alarm: The air quality detector is equipped with a digital 28 "TFT true color LCD and backlight to enable you to read clearly in a dark environment. During the measurement, when the value exceeds the normal value, the detector will give an alarm, and the color of the interface will change according to the risk level to ensure your safety.
• Applications and Services: It can help us detect the air quality in homes, kitchens, bedrooms, offices, schools, cars, hotels, travel, camping, parties and other places, especially places with infants, children and pregnant women. This product enjoys a one-year warranty and lifelong technical support. If you have any questions, please feel free to contact us.

Overview: GR-5800S air quality detector is a new PM2.5/PM10/HCHO/TVOC air monitoring device, which adopts the latest imported electrochemical sensor technology, laser sensor and single-chip technology. The product accurately measures PM2.5 and PM10 respirable particles, formaldehyde and other organic volatile gases (TVOC), which are displayed by LCD after being processed by the built-in microprocessor. Detection Range: PM2.5: 0~999.9 μg/m³ Resolution: 0.1ug/m³ PM10: 0~999.9 μg/m³ Resolution: 0.1ug/m³ Effective range of HCHO detection: 0-1.00 mg/m³ Maximum range of HCHO detection: 0-2.50 mg/m³ Resolution of HCHO: 0.01mg/m³ Effective range of TVOC detection: 0-10mg/m³ Resolution of TVOC: 0.05mg/m³ NOTE: Formula: Hazard value=PM2.5 value/5 + HCHO value*150 + TVOC value*28 Product Detail: Response time (T90):<30s Accuracy: ＜ 5% fs Battery capacity：2000mAh Product size：196 * 95 * 46mm/7.7*3.7*1.8 in Product weight：About 331g Color LCD Display Backlight Data Hold USB Rechargeable Auto/Manual Power Off What's Included? 1* GR-5800S PM2.5 HCHO TVOC detector 1* USB Cable 1* Storage Bag 1* Manual
