  • Page 6: Description

    English Description Application range The C 6F, O 6F and U 6F analyzers are used to measure individual components in gas mixtures. In conjunction with a certified EEx p safety device guaranteeing the pressurized enclosure, these analyzers can be used in hazardous areas of zone 1. The EEx p safety device guarantees defined pre-purging in the housing, and also the required pressurized enclosure during operation.

  • Page 7: Further Safety Measures

    English Further safety measures The sample gas and reference gas lines must terminate outside the hazardous area at a point with no danger; sample gas lines can be returned to the sampling point. When connecting combustible or non-combustible sample gases into the hazardous area, both the sample gas inlet and outlet must be provided with a flame inhibitor.
