10. It is an independent combustible gas alarm, which adopts gas-sensitive sensing technology and uses a microprocessor as the control core. It is a small gas safety product suitable for household use. It is used to continuously detect the concentration of indoor gas leakage. When the concentration reaches the set value, the detector will send out sound and light alarm
11. When the indoor gas concentration is lower than the alarm setting value, the detector will automatically return to the normal working state, which can avoid the occurrence of poisoning, explosion, fire and other personal casualties and property loss accidents caused by combustible gas leakage
12. With gas concentration display, you can know the situation at any time, convenient and intuitive, and make your home safer and more worry-free

Features:
1. Using high-quality semiconductor heating sensor, good stability
2. MCU intelligent control monitoring, SMT chip technology
3. With on-site sound and light alarm function.
4. Nixie tube display technology, showing the real-time leakage concentration.
5. Three indications: power indication—POWER, status indication—STATE, alarm indication—ALARM
