Feature: 1. 【Compact Size】: Easy to carry and use. This portable gases detector provides a fast response time and quick leak detection. It features a compact ABS machine body that is dustproof and drop-resistant, ensuring a long service lifespan. 2. 【High-precise Sensor \u0026amp; Multiple Gases Detection】: It adopts a highly sensitive semiconductor gases sensor for more accurate measurements. It can detect a variety of combustible gases to meet a variety of needs. Suitable for acetylene, ammonia, ethanol, gasoline, hexane, hydrogen, methane, naphtha, natural gases, paint thinner, propane, solvents, etc. 3. 【Adjustable Sensitivity】: It features adjustable sensitivity levels, with a high sensitivity mode for preliminary scanning of general areas and a low sensitivity mode to narrow down the areas to pinpoint accurate leak locations. It is convenient for users to safely test a variety of combustible gases to meet different testing requirements. 4. 【Versatile Use \u0026amp; Alarm Function】: With its buzzer and analogue bar alarm function, the measurement results are more intuitive to understand in real time. When a combustible gasleak is detected, the instrument will make a sound, and the concentration indication analogue bar display. When the environmental concentration is higher, the sound of the instrument becomes quicker, and more analogue bars are displayed. It also supports low battery display, backlight on/off, ℃ and ℉ adjustable, and automatic shutdown after 4 minutes of no operation. 5. 【Wide Applications】: Regular testing helps identify gases leaks caused by aging, damage, loosening, and other factors, thereby avoiding unnecessary losses and harm. This device quickly detects leaking combustible gases, ensuring safety and preventing potential hazards. Suitable for water heating device detection, gases pipeline detection, industrial waste gases detection, oil station operation, gases leak detection, chemical industry, refining, and chemical industry, etc. Specification: This leak detector is designed to quickly and reliably detect the leakage of combustible gases.
