- Extremely stable with low detection limit at 6 ppb
- Suitable for trace SF6 leak detection, with up to 24 channel multiplexing possible
- Capable of measuring up to 3x the maximum allowable concentration (MAC = 1000 ppm for SF6)
- System designed to minimize interference from vibration, and automatically compensate for temper-ature, pressure, and humidity interference.
