CH4 Sensor
FS01200A is a semiconductor methane sensor probe that is highly sensitive to polluting gases. It utilizes a multi-layer thick film manufacturing process to create a miniature ceramic substrate with a heating element on one side and a metal oxide semiconductor gas-sensitive layer on the other, connected by electrode leads and encapsulated in a TO-5 metal shell.
