GAS DETECTOR AND LEAKAGE-GAS DETECTION SYSTEM

A gas detector detects difluoromethane present in a remote target space. The gas detector includes a detection portion that detects the difluoromethane by using absorption of light of a predetermined wavelength. The predetermined wavelength is in a wavelength range of any of a first wavelength range...

Beschreibung
Zusammenfassung:	A gas detector detects difluoromethane present in a remote target space. The gas detector includes a detection portion that detects the difluoromethane by using absorption of light of a predetermined wavelength. The predetermined wavelength is in a wavelength range of any of a first wavelength range of 1659 to 1673 nm, a second wavelength range of 1724 to 1726 nm, a third wavelength range of 2218 to 2221 nm, a fourth wavelength range of 2463 to 2466 nm, a fifth wavelength range of 3316 to 3318 nm, and a sixth wavelength range of 9034 to 9130 nm.
