- Full maintenance functions with very easy zero and span adjustment.
- Proven reliability with years of experience – COSMOS gas sensors have a small zero drift, a small sensitivity decrease, and a long life.
- Zero suppression function cancels slight fluctuations of the reading due to environmental change.
- Compact Indicator/Alarm unit – W113 x H204 x D71.5 mm, Approx. 1.5kg.
- Battery provides backup power in case of a power failure, allowing continuous monitoring over 60 minutes after the failure (option).
