NDIR分析仪允许高灵敏度测量各种气体组件,包括CO2, CO, CH4, NO, and SO2. Additionally an O2measurement can be made with a built-in paramagnetic analyzer or external zirconia analyzer.

  • Infrared Gas Analyzer IR202

    The model IR202 is capable of measuring concentration of CO2, CO, CH4, SO2,使用非分散红外方法(NDIR),在测量o的同时没有处理气体中的组件2with the paramagnetic or zirconia method. It also provides high stability over long periods of time.
    一个maximum of 4 components including O2(or up to 3 components without O2measurement) are simultaneously measurable.

  • Infrared Gas Analyzer IR400

    The model IR400 measures the concentration of NO, SO2, CO2、公司和CH4contained in sample gas. Since this instrument incorporates a compact paramagnetic O2sensor, it allows measureing up to 5 componets simultaneously by using the built-in O2sensor (up to 4 components if O2sensor is excluded).

For the management of raw materials in the pharmaceutical and cosmetics industries, a manual titration method presents many difficulties. Yokogawa developed the NR800 FT-NIR Analyzer, and with this system, measurements are reliable and stable. It is much easier to control quality.


We, Advanced Technology Research Center of Corporate R&D Headquarters, have developed an interference measuring technology, which is the fundamental technology of Fourier Transform (FT) type spectroscopy, and have been supporting the commercialization of spectroscopic analyzers by the business division.
