  • Pellistors are less sensitive than semiconductor sensors to fluctuations in air pressure, relative humidity and ambient temperature,
  • however, more sensitive to such catalytic poisons as silicone, lead tetraethyl or heavy metals.
  • Their service life is max. 3 years, but they measure more accurately than semiconductor sensors.
  • Measuring range: 0-100% LEL.
  • Output 4-20 mA.
  • Measurable explosive gases and vapors:
    Methane (CH4), hydrogen (H2), propane (C3H8), alcohol, benzine; additional hydrocarbons on request.
