The MQ8 sensor is designed for the detection of hydrogen in potentially dangerous environments.
This sensor incorporates a highly sensitive, selective and rapid response to the presence of hydrogen in the environment.

  • High sensitivity and hydrogen selectivity
  • Quick response
  • Immune to signal saturation
  • The output covers 0.25 to 4.0% H2 in air (5 to 100% LFL)
  • Accuracy of +/- 0.25% hydrogen
  • Insensitive to CO and CH4
  • Insensitive to humidity, temperature and flow variation
  • It works in a variety of environments
  • Sensitivity adjustment
  • Durable and stable
  • 24 VCA power
  • Alarm relay output
  • External siren relay output
