It can accurately check whether gas leakage or not, avoiding gas explosion, protecting life and property. Notes: it only detects combustible gases, can not detect CO2.
This gas detector pen will send out a visual and audible alarm if any combustible gas is detected. As the concentration goes up, the audible alarm beep more frequently and the screen flashes red with a bar graph indicating the approximate strength detected. LCD display with green backlight ensures clear visibility even in dim light. It has a low-battery indicator. Auto power off after about 5 minutes if there are no operation.
High and low sensitivity are switchable for different scenarios. Low sensitivity detects 500-1000ppm. High detects 50-500ppm. Set high sensitivity to find small gas leaks, set low sensitivity to find larger explosive gas leaks. Press the “S” button to switch sensitivity. When the “S” button is lit up, it is in high sensitive mode, which is the default. Pressing the “S” button will switch it to low sensitive mode, where the “S” button will not be lit.
