Online Gas Detection System (NV-100)


Online Gas Detection System (NV-100)

Features
  • Full maintenance function with very easy zero and span adjustment.
  • Proven reliability with years of experience - COSMOS gas senaors 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 - W113xH204xD71.5mm, approx. 1.5kg.
  • Battery provides backup power in case of a power failure, allowing continuous monitoring over 60 minutes after the failure. (option)

Type Explanation
  • C For combustible gas
  • H For combustible gas (High sensitive)
  • D For toxic gas/semiconductor manufacturing gas
  • S For oxygen
