Product Overview
This portable air quality monitor is designed to detect the most common harmful gases in indoor environments: Formaldehyde (HCHO) and Total Volatile Organic Compounds (TVOC). It also measures temperature and humidity, providing you with a complete picture of your indoor air quality.
Whether you have just moved into a new home, installed new furniture, or simply want to ensure a healthy environment for your family, this tester helps you stay informed and take action when needed. Ideal for home, office, school, laboratory, hotel, and any indoor space.
Key Features
Dual Gas Detection – Accurately measures HCHO (0–0.615 mg/m³) and TVOC (0–2.000 mg/m³) using highsensitivity thick film semiconductor sensors.
Temperature & Humidity Monitoring – Displays ambient temperature and humidity alongside air quality readings for comprehensive environmental assessment.
Large HighDefinition LCD Screen – Blue backlit display with white characters for easy reading, even in lowlight conditions.
Smart Alarm System – Builtin buzzer alerts you when air quality reaches unhealthy levels, so you can ventilate or take protective measures immediately.
96 Groups Data Storage – Automatically records one set of data every 15 minutes, storing up to 96 groups for a full 24hour monitoring cycle (data will cycle after 24 hours).
LongLasting Battery – Powered by a 2000mAh rechargeable lithium battery, providing up to 15 hours of continuous operation with backlight on, and up to 24 hours with backlight off.
Easy Operation – Touch keys and IMB panel for intuitive control; switch between Celsius and Fahrenheit with a long press.
Auto Power Off – Automatically enters black screen protection after 30 minutes of inactivity, and shuts down after 2 hours if not used (can be disabled in settings).
Convenient Charging – TypeC USB charging port, compatible with standard mobile phone cables and DC5V adapters.
Health Index Reference Table
| Air Quality Level | HCHO (mg/m³) | TVOC (mg/m³) | Meaning |
| Good | < 0.08 | < 0.262 | Safe and healthy |
| Slight | 0.08 – 0.2 | 0.262 – 0.650 | Mild pollution – consider ventilation |
| Unhealthy | 0.2 – 0.5 | 0.650 – 1.630 | Unhealthy – take action to improve air |
| Hazardous | > 0.5 | > 1.630 | Dangerous – leave the area and ventilate immediately |

Important Usage Notes
Before first use, open the battery compartment and connect the battery.
Each time the unit powers on, it will count down 200 seconds for sensor preheating. Please perform preheating in a clean environment.
Do not block the air inlet and outlet during operation.
Avoid using in dusty, high humidity, high temperature, or strong magnetic field environments.
Use only standard DC5V power adapters for charging.
Wipe the housing with a dry cloth periodically. Do not use abrasives or solvents.
