220 V Trace Oxygen Analyzer ( Zirconium Oxide )
CW-200A type (LCD) zircomium oxide oxygen content analyzer is composed by a ZrO2 detector and an intelligent signal convertor, of which the core is a microprocessor. It with linear analogue signal output, is used for the online detecting of oxygen content in the tested gas. CW-200A is convenient and reliable to operate, and easy to maintain.
It has the applications as below:
(1)the generation of nitrogen by the separation of air, and the automatic analysis of oxygen content in chemical processes; (2)the oxygen content analysis in the protective gas of high-temperature sintering furnace for magnetic materials; (3)the oxygen content analysis in the protective gas of electronic industries; and (4) the oxygen content analysis in glass and building materials industries.
