The SGAS701 is a solid-state chemiresistor sensor designed to detect hydrogen in air. The sensor uses an integrated heater with highly sensitive MOx material tailored for detection of hydrogen.

Features

  • High sensitivity to low hydrogen concentrations (10 to 1000 ppm)
  • Fast response time (15 seconds at 100 ppm)
  • Environmental temperature range of -20°C to 50°C
  • Environmental humidity range of 0% to 90% RH, non‑condensing
  • Low dependence on flow rate
