Overview

JW-05-4CH is described as the world's first four-channel NDIR methane sensor for residential and commercial gas alarms. Comparing signal patterns across four channels with smart compensation rejects ethanol and acetic acid to reduce false alarms; it is UL1484 compliant with a 10+ year life.

Key Features

  • NDIR technology
  • Four-channel design, superior sensitivity to methane gas
  • Excellent resistance to acetic acid and ethanol
  • High accuracy over full temperature range
  • Long-term stability
  • Long lifespan over 10 years
  • Compact size, easy for integration
  • Compliant with UL1484
