Old Kahn Gas Out to Panametrics Gas (Ar) In New Kahn Comparing Old Kahn to New Kahn Hygrometer • Kahn “Cermet II” has metalized ceramic sensor that is supposedly compatible • with harsh gases (unlike Al-oxide sensor of Panametrics) • Old Kahn cumulative exposure to CF4 for 3-4months • Compare old Kahn to New Cermet II unit by flowing Ar in parallel through both sensors
