Indicating Moisture Trap

  • Reduces water to less than 10 ppb; indicator changes from yellowish-green to blue at 5% relative humidity.
  • Prepurged for fast stabilization.
  • Reduces noise from high-sensitivity detectors.
  • Heavy-walled glass body prevents oxygen and water infusion.
  • 10 µm frit prevents microparticulate damage to needle valves and flow controllers.
  • Maximum operating pressure: 100 psi (689 kPa).
