Model 20/2 Hydrocarbon
Analyzer -
FID Dual Channel, Oven Heated Total Hydrocarbon
Analyzer
The VIG Industries, Inc. Model 20/2 is a microprocessor
based, oven heated total
hydrocarbon analyzer for high accuracy, sensitivity and stability.
The Model 20/2 is designed to continuously measure two points.
The Model 20/2 utilizes two flame
ionization detectors (FID). The flame ionization detectors, sample
filters, all sample lines, solenoid valves,
pump heads, capillaries, and other components that come in contact with the
samples are maintained in a temperature-controlled heated oven to prevent
condensation, and to provide repeatable, reliable performance in the analysis of
a wide varieties of hydrocarbon concentrations in gaseous mixtures or in ambient
air.

Features
Options
- 4-20mA output - no extra charge
- Automatic calibration
- Automatic ignition
- Automatic purge
- Built-in internal cleaning system
- External zero air generator

- The user selectable fuel option allows the
end user to select between pure hydrogen and a hydrogen / helium mixture for
the analyzer's fuel supply. This is all done internally by the microprocessor
simply by pressing a key on the front panel. The analyzer will automatically
adjust the fuel flow to accommodate the selected fuel.
