# Product Introduction
Panametrics Zirconia Oxygen Analyzer CGA 351
Adopting an advanced zirconia sensor, the zirconia oxygen analyzer can accurately measure oxygen content in process gases. The microprocessor-based electronic unit enables measurement ranging from ppm level to 100% oxygen.
# Applications and Uses
The CGA 351 Zirconia Oxygen Analyzer is suitable for monitoring and/or controlling high-purity gas streams or atmospheres in processes such as air separation, heat treatment, ceramic manufacturing and other industrial processes. A suitable sampling system may be required for dirty or wet gas applications.
