1. Product Overview
The Jectse Air Quality Monitor is designed to provide real-time detection of various indoor air pollutants. This device utilizes advanced semiconductor, infrared, and electrochemical detection technologies to accurately measure levels of Carbon Dioxide (CO2), Total Volatile Organic Compounds (TVOC), Formaldehyde (HCHO), Particulate Matter 2.5 (PM2.5), and Particulate Matter 10 (PM10).
Its compact and portable design makes it suitable for use in homes, offices, schools, and hotels, ensuring you are aware of your indoor air quality.

2. Setup Guide
2.1. Charging the Device
Before initial use, fully charge the air quality monitor. The device features a built-in 1200mAh rechargeable battery, providing approximately 5-6 hours of continuous operation on a full charge. Use the provided USB Type-C cable to connect the monitor to a compatible USB power source (e.g., computer, wall adapter).

2.2. Initial Power On
Press and hold the power button located on the side of the device until the display illuminates. The monitor will perform a brief self-calibration upon startup.
2.3. Optimal Placement
For accurate readings, place the monitor in an area with good air circulation, away from direct drafts, windows, or vents that might skew readings. The device is designed with ventilation openings on both sides and the back to facilitate convective airflow for precise real-time detection.

3.2. Detected Parameters
The monitor provides readings for the following air quality indicators:
- HCHO (Formaldehyde): Measured in mg/m³.
- TVOC (Total Volatile Organic Compounds): Measured in mg/m³.
- PM2.5 (Particulate Matter 2.5): Measured in ug/m³.
- PM10 (Particulate Matter 10): Measured in ug/m³.
- CO (Carbon Monoxide): Measured in ppm.
- CO2 (Carbon Dioxide): Measured in ppm.

4. Maintenance
4.1. Cleaning
To maintain optimal performance, regularly clean the exterior of the device with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water. Ensure the ventilation openings are free from dust and debris.
4.2. Battery Care
For long-term battery health, avoid completely discharging the battery frequently. If storing the device for an extended period, charge it to approximately 50% and recharge every few months.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery or power cable issue. | Charge the device using the provided USB-C cable. Ensure the cable and power source are functional. |
| Readings appear inaccurate or fluctuate wildly. | Improper placement, blocked ventilation, or environmental interference. | Relocate the device to an area with stable air circulation. Ensure ventilation holes are clear. Avoid placing near strong air currents or chemical sources. Allow device to stabilize for a few minutes after moving. |
| Screen is blank or unresponsive. | Device is off, battery is depleted, or a software glitch. | Press the power button to turn on. Charge the device. If unresponsive, try a soft reset by holding the power button for 10-15 seconds. |
