FID Single Channel, Oven Heated Total Hydrocarbon Analyzer
The VIG Industries, Inc. Model 20 is a microprocessor based, oven heated total hydrocarbon analyzer for high accuracy, sensitivity and stability. The Model 20 is designed to continuously measure one point.
The Model 20 utilizes a flame ionization detector (FID). The detector, all sample lines, and all solenoid valves that come in contact with the sample are maintained in a controlled, heated oven to prevent condensation, and to provide reliable performance in the analysis of concentrations of wide varieties of hydrocarbons in gaseous mixtures and in ambient air.
