1. Introduction
The AEGTEST AGT-2459 is a portable carbon monoxide (CO) detector designed to provide rapid and accurate detection of CO levels in various environments. This device features a high-precision DDS sensor, multiple alarm modes (sound, light, and vibration), and a clear TFT color screen for easy reading. Its compact, rechargeable design makes it suitable for home, travel, industrial, and mobile operations, ensuring personal safety by alerting users to dangerous CO concentrations.
2. Important Safety Information
Carbon Monoxide (CO) is a colorless, tasteless, and odorless toxic gas, often referred to as the "Invisible Killer." Inhaling high concentrations of CO can lead to serious health risks, including headache, nausea, difficulty breathing, and even coma or death. This detector is designed to alert you to the presence of CO, but it is not a substitute for proper ventilation and maintenance of fuel-burning appliances. Always ensure adequate ventilation and regularly inspect potential CO sources.
Potential Sources of Carbon Monoxide:
- Fireplaces
- Water Heaters
- Gas Stoves
- Car Exhaust
- Charcoal Grills
- Portable Generators
Hazards of Carbon Monoxide Exposure:
- Headache
- Nausea
- Difficulty Breathing
- Loss of Consciousness / Coma
In case of an alarm, immediately move to fresh air and seek medical attention if symptoms persist.

6. Setup
6.1 Initial Charging
Before first use, fully charge the AGT-2459 detector. Connect the provided Type-C USB charging cable to the device and a compatible USB power source. The battery indicator on the TFT screen will show charging status. A full charge typically takes 1-2 hours.
Image: The device features convenient Type-C charging for extended use.
6.2 Power On/Off
- To Power On: Press and hold the red power button (ⓘ) for a few seconds until the screen illuminates. The device will undergo a 10-second warm-up period.
- To Power Off: Press and hold the red power button (ⓘ) until the screen turns off.
7. Operating Instructions
7.1 Interpreting the Display
The TFT color screen displays real-time CO concentration in Parts Per Million (PPM). It also shows the battery level and the current alarm threshold setting.
7.2 Adjusting Alarm Thresholds
The AGT-2459 allows you to customize the alarm thresholds (24-500 PPM) to suit different environments or safety requirements.
- Press the OK button to enter the menu.
- Use the Up (▲) and Down (▼) buttons to navigate to the "Alarm" setting.
- Press OK to select and then use the Up/Down buttons to adjust the desired PPM threshold.
- Press OK again to confirm your selection.

7.3 Using the Flashlight
Press the flashlight button (💡) located at the bottom of the control panel to turn the built-in flashlight on or off. This is useful for measurements in low-light conditions.
8. Testing Before Use
To ensure the detector is functioning correctly, it is recommended to perform a test before critical use. You can test the device using controlled sources of CO, such as:
- Cigarette Smoke: Briefly expose the sensor to cigarette smoke.
- Burning Paper in Low-Oxygen Conditions: Carefully burn a small piece of paper in a confined, low-oxygen space (e.g., under a glass jar) and expose the sensor to the resulting smoke.
When exposed to CO, the device should register a reading and trigger its alarms if the concentration exceeds the set threshold. If the device does not respond as expected, refer to the Troubleshooting section.
9. Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the detector in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Battery Care: Recharge the device regularly to maintain battery health, even if not used frequently. Avoid fully discharging the battery for extended periods.
- Sensor Longevity: The DDS sensor is designed for durability. Avoid exposing the sensor directly to water or harsh chemicals.
10. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery or no charge. | Charge the device using the provided Type-C USB cable. |
| Inaccurate readings or no detection. | Sensor obstruction or malfunction. | Ensure the sensor area is clear. Perform a test with a known CO source. If issues persist, contact support. |
| Alarm triggers frequently without apparent CO source. | Alarm threshold set too low or presence of other gases. | Adjust the alarm threshold to a higher, appropriate level. Ensure no other interfering gases are present. |
| Screen is dim or unresponsive. | Low battery or device malfunction. | Charge the device. If the problem persists after charging, contact support. |
