Model 700 FTIR - Heated Sampler

Provides temperature-control circuits for oven, pump, internal heated sample line (up to 10 ft. between sampler and analyzer) and heated jacket(entry to analyzer). Ensures that critical components are heated to 191 °C

Model 600 CLD - Chemiluminescence Analyzers

The chemiluminescence method is used to measure the reaction between ozone and nitric oxide. In the NOx mode, the sample is routed through a converter. The resultant reaction is directly proportional to the total concentration of NOx. The reliability and rapid response time of CAI CLD analyzers make them particularly well-suited for the following applications:
