Detecting CO as one of the SF6 decomposition products allows<br \/>\nearly diagnosis of apparatus failure. With the spectrophone consisting of an 8 kHz T-shaped quartz tuning fork and a pair of resonator tubes for photoacoustic detection, a quantum cascade laser (QCL) with central wavelength of 4.61 \u00b5m is used as the light source of the optical sensor.
