Model 8800 NMHC NonMethane Hydrocarbon Analyzer
 |
The Model 8800 NMHC is based on a flame ionization detector (FID) and catalyst. It is designed to measure the total, methane, and non-methane hydrocarbon content of gas samples. The analyzer can be configured with internal components for a single or multipoint analysis of ambient, non-condensing gas samples.
