Oxygen Analyzer for Baking Furnaces and Nitrogen Reflow Ovens

RF-30 Compact Oxygen Analyzer, RF30RF-30 Compact Oxygen Analyzer

The RF-30 oxygen analyzer is designed to monitor the oxygen content in baking furnaces and nitrogen reflow ovens in the electronic industry.  The RF-30 uses a compact precision zirconia oxygen sensor for stable and highly accurate measurement from low ppm up to 100% Volume oxygen.  The RF-30’s small size allows for easy integration into most all applications.
