HeathTech Detecto-Pak OVD Leak Compound Detector Portable Flame-Ionization amplifier Pilot tone squelch for eliminatingThe Heath DETECTO PAK OVD is a portable flame ionization detector utilized for detecting volatile organic compounds. The DETECTO PAK OVD uses a 40% hydrogen 60% nitrogen fuel source for the flame in the ionization chamber. A positive draw intake pump within the instrument draws a sample into the chamber. Any VOC in the flame and combustion process releases ions from the carbon atoms in the VOC molecule. The released ions are attracted to a positively
