  • ZASMHBA0002204
    Schematic of sensing element of a heated l|*., 5 anode halogen leak detector used at atmo''U" spheric pressure for leak location with detector probe system. Positive-ion current from heated alkali electrode responds to refrigerant gases and other halogenated hydrocarbon tracer gases.
  • Federal Register > Thursday, July 27, 2006 > [71 FR 42724] National Perchloroethylene Air Emission Standards for Dry Cleaning Facilities
    … with the second option we proposed for new co-residential sources and use refrigerated condensers and secondary … These facilities will also have to conduct weekly leak inspections using a leak detection device such as a halogenated hydrocarbon detector .
  • Federal Register > Wednesday, December 21, 2005 > [70 FR 75884] National Perchloroethylene Air Emission Standards for Dry Cleaning Facilities
    The NYSDEC requires that co-residential dry cleaning machines have refrigerated condensers and secondary carbon adsorbers, and … Facilities must conduct weekly leak inspections using a leak detection device such as a halogenated hydrocarbon detector .
  • ISA MEASRMNT CNTRL BASC - Measurement and Control Basics
    They are also used to detect leaks in refrigerant systems and aerosol packaging as well as to detect breakthroughs from carbon adsorption beds. Flame ionization detectors (FIDs) are often employed to measure total hydrocarbon concentrations in ranges from 0 to 1 ppm and 0 to 12,000 ppm.
  • Refrigerant Leak Detector
    NGD268 - Portable Gas Leak Detector Detect methane, natural gases, coal gases, hexane, propane, ethane, Butane, pentane, isopropyl alcohol, halogenation hydrocarbon , (Methanol, Ethanol, Butanol) aether, ketone (butone, protone), Hydrogen, toluene, and other compounds, (gasoline, industrial solvent, lacquer, refrigerant , sulfur dioxide, ammonia, sulfured hydrogen, acetic acid, etc)Â .
  • A Method to Measure Air Conditioning Refrigerant Contributions to Vehicle Evaporative Emissions (SHED Test)
    The SHED hydrocarbon analyzer, a flame ionization detector (FID) which is calibrated to provide a report in grams of hydrocarbon (or ppm propane), does not differentiate between various HC components. The issue of the possible contribution of refrigerant leaks to evaporative hydrocarbon (HC) emissions measured in the SHED test has been considered earlier [1].
  • Jointly Sponsored Research Program Energy Related Research
    The new device called the X-Wand screening tool is based on a heated diode refrigerant leak detector sensor. The sensor is selective to halogens and does not respond to fuel hydrocarbons or water vapors.
  • Refrigerant Leak Detectors / General Tools & Instruments Co., LL
    NGD268 - Portable Gas Leak Detector Detect methane, natural gases, coal gases, hexane, propane, ethane, Butane, pentane, isopropyl alcohol, halogenation hydrocarbon , (Methanol, Ethanol, Butanol) aether, ketone (butone, protone), Hydrogen, toluene, and other compounds, (gasoline, industrial solvent, lacquer, refrigerant , sulfur dioxide, ammonia, sulfured hydrogen, acetic acid, etc)Â .
