1. Giới thiệu
The TOPTES PT199 is a portable combustible gas leak detector designed to identify the presence of various gases, including natural gas, methane, propane, butane, and LPG. This device helps pinpoint the source of gas leaks, contributing to household safety by reducing the risk of explosions. It features both visual and audible alarms to alert users to potential hazards.
2. Thông tin an toàn
- Quan trọng: If you smell gas, immediately follow all safety information provided by your gas provider. Do not rely solely on this device if you suspect a significant gas leak.
- The warm-up process for the detector should always be performed in a known 'clean' environment to ensure accurate results.
- The PT199 is specifically designed for detecting combustible gas leaks. It is not intended to detect fire-related gases such as carbon monoxide, carbon dioxide, hydrogen cyanide, or sulfur dioxide, and should not be used as a fire alarm device.
- Ensure proper ventilation when investigating a gas leak.

5. Thiết lập
5.1 Lắp đặt pin
- Unscrew the battery cap at the bottom of the device.
- Lắp hai (2) pin AAA, đảm bảo lắp đúng cực (+/-).
- Vặn chặt nắp pin vào đúng vị trí.
5.2 Khởi động ban đầu
After battery installation, the device requires a warm-up period for calibration:
- Bấm nút nguồn (U) to turn on the detector.
- The device will undergo a 30-second warm-up process. During this time, ensure the detector is in a clean, gas-free environment for accurate calibration.
- The device is ready for use once the warm-up is complete and the display shows a stable reading.

6. Hướng dẫn vận hành
6.1 Bật/Tắt nguồn
- To power on, press and hold the red power button (Ucho đến khi màn hình sáng lên.
- To power off, press and hold the red power button (U) again until the display turns off. The device also features an auto-off function after 5 minutes of no operation or gas detection.
6.2 Gas Detection Process
Once the device has completed its warm-up, proceed with detection:
- Slowly move the sensor tip (the top part of the detector) towards the area where a gas leak is suspected.
- Maintain a detection distance of approximately 1-5 cm from the potential leak source.
- Observe the LCD screen and listen for the audible alarm.
6.3 Chế độ nhạy cảm
The PT199 offers two sensitivity modes:
- High Sensitivity Mode: Indicated when the 'S' button light is on. This mode is ideal for detecting small leaks or for initial scanning of an area.
- Low Sensitivity Mode: Indicated when the 'S' button light is off. This mode can be used to narrow down the exact location of a larger leak.
- Press the green 'S' button to toggle between high and low sensitivity modes.
6.4 Hành vi báo động
- Báo động trực quan: The LCD screen will turn red, and a bar graph will indicate increasing gas levels.
- Báo động bằng âm thanh: A beeping sound will activate. The frequency and intensity of the alarm will increase with higher gas concentrations.
- The alarm will continue to sound until the combustible gas concentration drops below 5% of the lower explosive limit.
7. Bảo trì
- Vệ sinh: Lau thiết bị bằng vải mềm, khô. Không sử dụng chất tẩy rửa có tính mài mòn hoặc nhúng thiết bị vào nước.
- Thay thế pin: Replace batteries when the low battery indicator activates (below 2.4V). Refer to Section 5.1 for installation instructions. Note that rechargeable batteries (1.2V) may not provide sufficient voltage for the device to operate correctly; alkaline batteries (1.5V) are recommended.
- Chăm sóc cảm biến: Keep the sensor tip clean and free from obstructions. Avoid exposing the sensor to extreme temperatures or harsh chemicals.
KHAI THÁC. Xử lý sự cố
| Vấn đề | Nguyên nhân có thể | Giải pháp |
|---|---|---|
| Thiết bị không bật. | Low or depleted batteries; incorrect battery installation; incompatible battery type. | Replace with fresh AAA alkaline batteries, ensuring correct polarity. Rechargeable batteries may not provide sufficient voltage. |
| Kết quả đọc không chính xác hoặc không nhất quán. | Warm-up performed in a contaminated environment; sensor obstructed or dirty. | Perform warm-up in a clean, gas-free area. Clean the sensor tip. |
| Âm thanh báo động liên tục. | Persistent gas leak detected. | The alarm will continue until gas concentration is below 5% LEL. Address the gas leak source immediately. |
| Cannot pinpoint small leaks. | Incorrect sensitivity mode. | Ensure the device is in high sensitivity mode (S button light on). |
