- High-Precision Sensors: Advanced electrochemical sensor for CO (0–1000ppm, 0.5s refresh rate) and natural gas (alarm at 10% LEL).
- Clear Display: 2.8-inch color LCD shows real-time data.
- Audible & Visual Alerts: 85dB alarm and flashing red light with a three-color indicator (green/yellow/red) for immediate feedback.
- Portable Design: Compact (105g) with a magnetic back for easy attachment to metal surfaces.
- Long Battery Life: 2000mAh rechargeable battery provides up to 300 hours of standby time.
- Type-C Charging: Convenient and fast charging.
- Integrated Flashlight: For added utility in low-light conditions.
Setup
- Initial Charge: Fully recharge the device using the provided Type-C charging cable before its first use. Connect the cable to the device and a compatible USB power source. The battery indicator on the display will show charging status.
- Power On: Press and hold the power button until the display illuminates.
- Acclimatization: For optimal performance and accurate readings, allow the detector to acclimatize for 2-3 minutes after powering on. During this time, the device calibrates its sensors to the ambient environment.
- Placement: Position the detector in the desired monitoring area. Utilize the magnetic back to attach it to any suitable metal surface, or use the magnetic lanyard for hanging. Ensure the display is visible and the alarm is audible.

Operating Instructions
- Power On/Off: Press and hold the power button to turn the device on or off.
- Monitoring: Once powered on and acclimatized, the device will continuously monitor CO, natural gas, temperature, and humidity. Readings are displayed in real-time on the 2.8-inch color LCD.
- Display Information: The screen shows CO levels in PPM, natural gas status (if detected), temperature in °C or °F, humidity in %RH, and battery level.
- Alarm Activation: If dangerous levels of CO or natural gas are detected, the device will trigger a loud 85dB audible alarm and a flashing red light. The screen's background color will also change (e.g., to red for high alert).
- Flashlight Function: Press the designated button (if available, typically indicated by a light icon) to activate or deactivate the built-in flashlight.

Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Charging: Recharge the battery when the low battery indicator appears on the display. Use only the provided Type-C cable or a compatible charger.
- Storage: Store the detector in a cool, dry place away from direct sunlight and extreme temperatures when not in use for extended periods.
- Avoid Immersion: Do not immerse the device in water or any other liquids.
- No Disassembly: Do not attempt to disassemble or repair the device yourself. This will void the warranty and may cause damage or malfunction.
Troubleshooting
- Device Not Turning On: Ensure the battery is fully charged. Connect to a power source and try again.
- Inaccurate Readings: Allow the device to acclimatize for 2-3 minutes after powering on. Ensure it is not exposed to extreme temperatures or humidity immediately after startup.
- Alarm Sounds: If the CO or natural gas alarm sounds, immediately ventilate the area by opening windows and doors. Evacuate the premises if necessary and contact emergency services or a qualified technician to investigate the source of the gas leak. Do not re-enter until the area is confirmed safe.
- Display Issues: If the display is dim or unresponsive, try recharging the device. If the issue persists, contact customer support.
