The beneficial effects of the utility model：
The SF of the utility model6Gas integrated optical detection apparatus can be simultaneously respectively to SF6The purity of gas, humidity and
Decomposition product SO2、CO、H2S is detected, and is realized to SF6The complete detection of gas；The utility model is to SF6Gas is examined using light
Instrument is surveyed, improves the accuracy and sensitivity of detection, and optical means detection need not demarcate repeatedly, also decline there is no irreversible
Subtract, detection data are permanently effective；The tail gas that the utility model detects detecting instrument using no pollution blowback device recycles,
So that the not outer row of Site Detection gas, improves entire SF6The process of cycling and reutilization, reduces environmental pollution；This practicality is new
Type solves SF existing in the prior art6Gas detecting instrument is to SF6It is not comprehensive that gas decomposes analyte detection；Detecting instrument precision and
Poor sensitivity, it is necessary to demarcate repeatedly；The technical problems such as the directly outer row's environmental pollution of exhaust gas is big after the completion of detection.
