6 in 1 Air Quality Monitor Indoor, CO2 Detector with PM2.5 HCHO TVOC Temp Humidity, CO2 Monitor, Carbon Dioxide Meter with LCD Display Black for Home, Office,Wine Cellar, Car

• 【6 in 1 Comprehensive Air Quality Monitoring】 This air quality monitor measures six key environmental factors: carbon dioxide (CO2), PM2.5 particulate matter, formaldehyde (HCHO), total volatile organic compounds (TVOC), temperature, and humidity. Unlike standard 5-in-1 monitors, this co2 detector includes PM2.5 detection for a more thorough assessment of indoor air pollution from dust, smoke, and allergens.
• 【Real-Time Updates with High-Precision Chip】 The indoor air quality monitor refreshes readings every second, providing continuous real-time tracking of air conditions. A high-performance analysis chip captures weak currents generated during electrochemical reactions, enabling accurate detection of CO2 levels and other pollutants. This co2 monitor delivers reliable data without requiring manual calibration.
• 【Clear LCD Display with Adjustable Brightness】 The large LCD screen shows CO2 concentration, PM2.5 levels, HCHO, TVOC, temperature, humidity, and battery status in easy-to-read digits. Colour-coded indicators provide at-a-glance air quality assessment. Screen brightness can be adjusted using touch buttons, ensuring clear visibility in both bright daylight and dark environments.
• 【Portable Design with Long Battery Life】 Powered by a 3.7V 1200mAh lithium battery, this portable air quality monitor offers 240 to 360 minutes of standby operation on a full charge. The compact, lightweight black unit fits easily in a bag or pocket, making it suitable for use at home, in the office, in the car, or in grow tents and wine cellars.
• 【Durable Build for Everyday Use】 Constructed from sturdy ABS material, this carbon dioxide detector resists impact and scratches, ensuring long-lasting performance. The black finish gives it a sleek, modern appearance that blends with any decor. This air quality monitor indoor is a practical tool for maintaining a healthy living or working environment.

What this product contains This 6-in-1 air quality monitor package includes: one black monitor unit with LCD display, one USB charging cable, and a user manual. The device comes pre-calibrated and is ready for use straight out of the box. How to use To begin using the air quality monitor, press the power button to turn on the device. The LCD screen will light up and display readings for all six parameters: CO2 concentration (ppm), PM2.5 particulate matter (μg/m³), formaldehyde HCHO (mg/m³), TVOC (mg/m³), temperature (°C), and relative humidity (%). Place the monitor in the room or space you wish to assess. For accurate readings, position the device at breathing height (approximately 1 to 1.5 metres above the floor) and away from direct airflow from windows, doors, or air conditioning vents. The monitor updates readings every second, allowing you to observe changes in real time. The colour-coded display helps you quickly determine air quality status—green indicates good, yellow signals caution, and red warns of poor air quality requiring action. For CO2 monitoring, typical outdoor levels are around 400–450 ppm. Indoor levels above 1000 ppm may indicate inadequate ventilation. PM2.5 readings below 12 μg/m³ are considered good, while higher values suggest the presence of dust, smoke, or other fine particles. HCHO and TVOC levels should remain as low as possible—elevated readings may indicate off-gassing from furniture, paints, or cleaning products. Precautions The sensors are pre-calibrated at the factory and do not require user calibration under normal use. If readings appear unusual, place the monitor in fresh outdoor air for 10–15 minutes to allow the sensors to reset. This air quality monitor is intended for indoor use and is not waterproof.
