Natural Gas Leak Detector with Audible & Visual Alarm, Portable Gas Sniffer for Home

Power Saving and Battery Life Indicator

The TopTes gas leak detectors feature automatic power-off functionality, which turns off the device after 5 minutes of inactivity or lack of gas detection. This helps to conserve battery life. Additionally, the low battery indicator will appear on the screen when the battery voltage drops below 2.4V, alerting the user to replace the batteries.

Adjustable Sensitivity with Dual Range

The gas leak detectors offer two sensitivity modes to cater to different detection requirements:

1. Low Sensitivity Mode: 500 to 1,000 ppm (based on methane detection)
2. High Sensitivity Mode: 50 to 500 ppm (based on methane detection)

Users can easily toggle between the two modes by pressing the "S" button, with the button light indicating the current sensitivity setting.

FAQs

1. How to set up the detector for use?

2. Turn on the device and wait 30 seconds for it to warm up. Ensure the warm-up is done in a known "clean" environment for accurate results.

3. How to determine the current sensitivity mode?

4. When the "S" button light is on, the detector is in high sensitivity mode. When the light is off, it is in low sensitivity mode.

5. Does the alarm continue until the situation is resolved?

6. Yes, the alarm will sound until the combustible gas concentration drops below 5% of the lower explosive limit.

7. How close does the detector need to be to detect pipeline gas leaks?

8. Generally, 1-5 cm, depending on the severity and concentration of the gas leak.

9. Can the sensors be replaced?

10. No, sensors are not sold separately. If the sensor fails within 3 years of purchase, please contact the manufacturer for exchange service.

11. What is the difference between a gas monitor and a gas leak detector?

12. Gas monitors are for continuous air quality monitoring, while gas leak detectors are used to locate the source of a gas leak.
