Abstract
The utility model relates to an infrared double wave SF6 gas quantifying leak detector, wherein, a gas collection pump (3), a double mirror air chamber (4), an infrared light supply (5), a dual pyroelectric infrared sensor (6), a data transmission circuit board (7) and a liquid crystal display (8) are connected sequentially in an isolated housing (2); the infrared double wave SF6 gas quantifying leak detector adopts a working principle that gas that is collected by the gas collection pump (3) is led in the double mirror air chamber (4), infrared rays emitted by the infrared light supply (5) permeates the gas, the specific infrared band specific to SF6 gas can be partly absorbed when passing through the SF6 gas, and the change of the infrared band can be detected by the dual pyroelectric infrared sensor (6) so as to reflect the content of the SF6 gas. The infrared double wave SF6 gas quantifying leak detector plays an important role in SF6 gas analysis in greenhouse effect and SF6 environmental pollution. The infrared double wave SF6 gas quantifying leak detector has the benefits that the content of the SF6 gas can be measured really, and the measurement can be carried out based on different SF6 gas concentration.
