生産終了

Features

  • 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)
