The invention discloses a novel combustible gas detector which comprises a housing, a gas inlet, a display screen, an on / off button, a detection button and an inquiry button arranged on the housing, a circuit main board, a microprocessor, a combustible gas sensor, a signal amplification circuit, a filter circuit, an analog-digital conversion circuit, a power supply, a memory and an alarm module arranged in the housing, and a fan which is arranged on the housing and penetrates through the housing. The combustible gas sensor is connected to the gas inlet and is successively connected to the microprocessor through the signal amplification circuit, the filter circuit and the analog-digital conversion circuit; the microprocessor is separately connected to the memory, the alarm module and the display screen, and the circuit main board is separately connected to the power supply, the on / off button, the detection button, the inquiry button and the microprocessor. The novel combustible gas detector disclosed by the invention is handheld, is convenient to operate, small in size and convenient to carry, can be taken to different sites to measure the content of combustible gas as needed, is convenient and practical, and has a very good application prospect.
Description
technical field [0001] The invention relates to the field of gas detection, in particular to a novel combustible gas detector. Background technique [0002] Combustible gases such as natural gas, liquefied petroleum gas, coal gas, hydrogen, etc. are prone to fire and explosion when exposed to fire or sparks in the air, posing a great threat to life and property. In order to prevent the explosion of combustible gas after reaching a certain concentration and ensure production safety, it is often necessary to install combustible gas detection and alarm devices in factories or places that produce and use combustible gas. The main component of this combustible gas detection and alarm device is a combustible gas sensor, which is usually fixed and can only detect combustible gas at a fixed location. It is very inconvenient when other locations or different locations need to be detected. The portability and ease of use of testing instruments play an important role in the effectiven...
