Abstract: A gas analyzer includes a housing adapted for insertion into a chamber. The housing has an open interior with a chemochromic sensor assembly arranged therein which includes a chemochromic media, an electronic color sensor that senses a color of the chemochromic media, and a processor. In operation, the housing is inserted into a chamber, the chemochromic media is exposed to a gas within the chamber, the chemochromic media changes color depending on the gas within the chamber, and the electronic color sensor detects the color of the chemochromic media and communicates a signal to the processor based on the detected color. The processor may be configured to generate gas detection information based on the signal received from the electronic color sensor. A transmitter in communication with the processor communicates at least a portion of the gas detection information from the chemochromic sensor assembly to remote monitoring equipment.
