Methanizer - Wikipedia

Methanizer is an appliance used in gas chromatography (GC), which allows the user to detect very low concentrations of carbon monoxide and carbon consists of a flame ionization detector, preceded by a hydrogenating reactor, which converts CO 2 and CO into methane CH contain a hydrogenation catalyst to achieve this conversion. Nickel is commonly used as the catalyst …

MQ-7 Carbon monoxide gas sensor module | Psalmchmart

MQ-7 Carbon monoxide gas sensor module detects the concentrations of CO in the air then outputs its reading as an analog voltage. It can measure concentrations of 10 to 10,000 ppm. Additionally, it can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5V. It also uses SnO2 material, whose conductivity is lower in clean air. Its conductivity increases as the ...
