Retractable Gas Leak Detector: The TopTes PT299 gas leak detector is a dependable and portable tool that allows you to adjust the pole's length, reaching the desired testing location for accurate detection of combustible gas leaks, including propane, methane, natural gas, LPG, gasoline, and more. (Note: Please wait for a 30-second warm-up time before operation) Telescope Pole for Easy Access: The PT299 natural gas detector helps you detect gas leaks in hard-to-reach areas such as pipelines, storage tanks, fireplaces, basements, and RVs. Extend the pole for gas leak inspection without getting too close to potential leakage points. Extension Range: 2.20 inches to 6.30 inches 5.60cm-16.00cm Alarm! See & Hear: When gas is detected, the PT299 responds in just 0.5 seconds. A visual and audible alarm promptly warns you of danger. Watch as 9 analog bars rise and the screen turns red, providing real-time feedback on gas concentration. The 75dB buzzer helps pinpoint gas leak locations. Detection range: 1%LEL to 10%LEL (100 to 5,000ppm, based on Methane) User-Friendly: Features a 30-second preheat countdown indicator and a low battery alert. When enabled, the PT299 gas leak detector automatically turns off after 5 minutes of inactivity to save energy. Additionally, it is designed with a non-slip texture and material, ensuring a secure and comfortable grip What You Get: Included in your package are 1× PT299 Gas Leak Detector, 2× AAA Batteries, 1× Storage Bag, and 1× User Manual The Toptes PT299 combustible gas leak detector is an efficient and portable combustible gas detector that excels at locating various gas leaks. Whether it's methane, natural gas, propane, liquefied petroleum gas, or gasoline, this handy tool can accurately pinpoint them all. With its high-sensitivity mode, you'll be instantly notified of methane presence at 1%LEL through audible and visual alarms. The PT299 goes beyond mere alerts by providing 9 informative bar graphs and numerical measurements in %LEL. This feature allows for a more intuitive understanding of the gas concentration in your surroundings. The PT299 features a telescoping sensor head bar, enabling you to detect gas leaks in tight or high spaces in homes and RVs.

Note: Before operation, please allow 30 seconds for calibration to ensure proper functionality.

Important Operation Instructions
Turn on the detector in an area where combustible gas is known not to be present.
Each time the device is turned on, it initiates a 30-second warm-up process, during which the device is unavailable.
It is recommended to use a lighter or gas stove gas to test the effectiveness of the detector (ensure gas is released but there is no flame).
Switch the sensitivity by pressing the [S] button. The detector is switched on in high sensitivity mode by default.
