At its core, the detector uses an imported catalytic combustion sensor, ensuring high accuracy and durability. This advanced sensor is highly responsive, and when the concentration of combustible gas reaches the alarm level of more than 5% LEL, both a voice and light alarm will be triggered, alerting you to potential danger immediately.Installation couldn't be easier. Thanks to its plug-and-play design, there's no need for complex set - up procedures, saving you a great deal of time and effort. The detector features a large color LCD display. This user - friendly interface offers high - definition readouts, enabling you to check important data with ease, even in low-light conditions. When a gas leak occurs, the detector doesn't just alert you with an 80dB alarm; it also displays the exact concentration level of the gas. Compatible with natural gas, propane, methane, butane, LNG, and LPG, it can be used in a wide range of settings, making it an ideal choice for any household concerned about gas safety..
