Dual Channel Heated Total Hydrocarbon Analyzer The VIG Industries, Inc. Model-20/2 is a dual channel, microprocessor based, oven heated total hydrocarbon gas analyzer designed for high accuracy, sensitivity and stability. The Model-20/2 uses two Flame ionization detectors (FIDs) For continuous measurement oF two independent sample streams. All components that come in contact with the sample through analysis are maintained in a temperature-controlled oven to prevent condensation, and to provide repeatable, reliable performance in the analysis oF a wide variety oF hydrocarbon concentrations in gaseous mixtures or in ambient air. •Automatic start-up / ignition •Heated sample pump heads •Two stage sample filters with exchangeable sintered stainless steel elements • PTFE isolated detectors (FIDs) •Automatic fuel shut off system •Automatic flame-out indicators •Adjustable alarm and oven settings •Automatic ranging • Precision 1 % of full scale • Fast response •Choice of Hydrogen or Hydrogen/Helium •Automatic calibration •Zero and calibration solenoids with •Second concentration level alarms • Internal combustion air supply •Purge and internal cleaning system • Dilution system • User selectable fuel (H2 or H2/He mixture) •Range recognition relays •Multi-point sequencer •Sample shut-off Process Monitoring- Continuous monitoring and alarm or control of: process gas streams utilizing organic solvents, crude oil, and other chemicals containing hydrocarbons. Efficiency Monitoring - Monitoring effluent of volatile organic compound (VOC) reduction equipment for environmental compliance, efficiency control of incinerators (Thermal or catalytic), scrubbers, carbon absorbers, and other abatement equipment, monitoring of catalytic converters, combustion and diesel engine efficiency.
