Explosion-proof process for infrared gas analyzer EIA-51d / p is, the change in concentration of gas to be measured in the sample gas, is the analyzer for continuous measurement by non-dispersive infrared absorption method (NDIR). Based on the electro-mechanical equipment explosion-proof construction standards in Article 5 of the international standard (IEC standard), you have passed the type test. Can be excellent selectivity and stability measurement.

Feature

  • Inherits the reliability and stability of the hydrogen explosion-proof corresponding conventional models (31 series), has been upgraded to the corresponding grade to "IIB + H 2".
  • To achieve a stable gas analysis from the mounting of the self-diagnosis function and control functions, as a new function, a self-diagnostic function to inform an anomaly, was added administrative functions.
    History and of calibration coefficients, such as automatic calibration feature that provides an option, safety of day-to-day management of, and support a reliable operation.
  • Visibility of improving equipment status at a glance, it is high visibility design. (Such as measurement and alarm display) operation state is also manifested in always LED, is easy to check the situation.
  • In order to support the compatibility to secure conventional series of replacement needs of the conventional models (31 series), such as mounting hole positions and body size, we are conscious of the physical compatibility.
  • Even if the interfering gas to the excellent selectivity sample gas coexist, accurate measurement values ​​can be obtained by mounting the interference correction type detector.
