1. Product Overview
The Airepair T700-2 is a portable gas detector designed for the real-time monitoring of liquefied petroleum gas (LPG), methane, and carbon monoxide (CO) concentrations. Equipped with a high-sensitivity semiconductor sensor, it provides rapid detection and alerts users to potential gas leaks, offering crucial safety protection in various environments.
Its compact, lightweight, and keychain-friendly design makes it highly portable and practical for both household and industrial applications, including barbecues, camping, RVs, kitchens, industrial gas sites, and food trucks.
2. Key Features
- Compact Design: Small, portable, and lightweight, designed to be easily carried, even attached to a keychain, without being noticeable.
- Ultra-Fast Response: Detects gas leaks with a response time of 0.5-2 seconds, providing timely warnings.
- High-Sensitivity Sensor: Built-in sensor continuously monitors LPG concentration and triggers a high-decibel alarm when preset safety thresholds are exceeded.
- Buzzer Alarm: An audible alarm sounds immediately when combustible gas concentration exceeds 50 ppm. The alarm frequency increases with higher gas concentration for a stronger warning.
- Multi-Gas Detection: Capable of detecting carbon monoxide (CO), methane (CH4), ethane (C2H6), propane (C3H8), ethylene (C2H4), propylene (C3H6), acetylene (C2H2), propyne (C3H4), and other flammable gases.
- Wide Application Range: Suitable for various environments including petroleum and petrochemical industries, industrial gas systems, gas pipelines, kitchens, natural gas extraction, and hospitality sectors.
3. Setup and Operation
3.1 Device Components
- Switch: Power On/Off control.
- Lanyard: For easy carrying and attachment.
- Indicator Light: Displays device status (preheating, alarm, charging).
- Type-C Charging Port: For charging the internal battery.
- Flared Opening / Horn Opening: Where the buzzer alarm sounds.
- Liquid and Gas Detection Port: The sensor area for gas detection.
3.2 Power On and Preheating
- Push the switch upward to turn on the alarm.
- Upon activation, the indicator lights will illuminate in sequence: red → blue → green.
- Once the green light remains steadily on, the preheating process is complete. The entire preheating time is approximately 30 seconds.
During preheating, the device calibrates its sensor for accurate readings. Avoid exposing the device to gas sources during this period.

3.3 Gas Detection and Alarm
- If the combustible gas concentration in the air is below 50 ppm, the device will not trigger an alarm.
- If the combustible gas concentration exceeds 50 ppm, the device will immediately trigger a high-decibel buzzer alarm.
- The frequency of the buzzer alarm will increase with higher gas concentrations, providing a more urgent warning.
3.4 Automatic Shut-off
The device features an automatic shut-off function. If no operation is detected for 5 minutes after preheating, the device will automatically power off to conserve energy.
3.5 Charging the Device
- Connect the device to a power supply using the provided Type-C charging cable.
- During charging, the red indicator light will flash.
- When the battery is fully charged, the green indicator light will flash.
4. Maintenance
- Cleaning: Regularly wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the gas detection port is free from dust and debris.
- Storage: Store the detector in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Battery Care: Charge the device regularly, even if not in frequent use, to maintain battery health. Avoid fully discharging the battery for extended periods.
- Avoid Contaminants: Keep the sensor area clear of liquids, oils, and other substances that could interfere with its operation.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery or device is off. | Ensure the switch is in the 'On' position. Charge the device fully using the Type-C cable. |
| Alarm sounds continuously without gas presence. | Sensor contamination or malfunction. | Ensure the sensor area is clean. Move to a well-ventilated area. If the problem persists, contact support. |
| Indicator lights do not cycle during preheating. | Device malfunction. | Ensure the device is fully charged. Try restarting the device. If the issue continues, contact support. |
| Device does not charge. | Faulty cable, power adapter, or charging port. | Try a different Type-C cable and power adapter. Ensure the charging port is clean and free of debris. |

7. User Tips
- Regular Testing: It is recommended to test the detector periodically (e.g., monthly) with a small, controlled gas source (like a lighter, briefly) to ensure it is functioning correctly.
- Optimal Placement: For best results, place the detector near potential gas leak sources, such as gas appliances, cylinders, or pipelines. Consider the density of the gas you are trying to detect (e.g., LPG is heavier than air, so place lower; methane is lighter, so place higher).
- Full Charge Before Use: Ensure the device is fully charged before taking it to outdoor or remote locations to maximize operating time.
- Avoid Obstructions: Do not cover the gas detection port or the horn opening, as this can impair detection and alarm effectiveness.
