Model CAI 600 Series - HFID Hydrocarbon Analyzer

The California Analytical Instruments Model 600 HFID Analyzers are designed to continuously measure the total concentration of hydrocarbons within a gaseous sample. The analyzers exhibit superior sensitivity and response time. The gaseous sample can be exhaust gases from an internal combustion engine, a combustion process or VOC abatement systems. The instrument can measure THC in the ppm or percent levels. All internal components are maintained at ...

Model 101 Series Heated Sample Diluter

The CAI Model 101 Heated Sample Diluter is designed to precisely dilute samples of high concentrations of analytes and/or humidity. The Diluter has an internal heated sample pump and temperature adjustable oven. All components in contact with the sample are maintained at the set oven temperature preventing condensation. Dry air is mixed with the sample to the required dilution ratio insuring no condensate will be introduced into the analyzer.
