ZAG-6L Zero Air Generator

The California Analytical Model ZAG-6L has been designed to operate continuously 24hours/ day, 7 days/week to provide a pure air source of “zero air” for use in analytical gas analysis equipment. The ZAG-6L completely eliminates the inconvenience and high costs of precision blended zero air cylinders. This is particularly important with instrumentation which, in addition to zero calibration air, requires pure air for burner combustion ...

1314/1412 Photoacoustic Analyzer

The Innova Photoacoustic gas analyzers are highly accurate, reliable, and stable. Two versions of the analyzer are offered, the Model 1412 which is configured for bench top operation and the Model 1314 which is configured for rack mounted operation. The measurement system is based on photoacoustic Infrared detection and provides the capability of measuring virtually any gas that absorbs in the infrared spectrum. Gas selectivity is achieved through the ...
