The gas analyzers in the EL6010 family are used for continuous quantitative
determination of individual gas components in gas mixtures.
The gas analyzers are capable of measuring non-flammable and flammable gases
under atmospheric conditions which can form an explosive environment (Zone 1).
The mixture ratio for these gases should be well under the lower explosive limit
(LEL) or well above the upper explosive limit (UEL). The initial and post-operation
conditions are exceptions to this requirement.
When specially equipped and when special conditions are fulfilled, the gas ana-
lyzers are capable of measuring pressurized non-flammable and flammable gases.
The gas analyzers should not be used to measure corrosive gases.
The gas analyzers in the EL6010 family are especially designed for use in explo-
sion risk areas. They are certified in accordance with European Directive 94/9/EC
("ATEX Directive").
The housings are pressure-tight capsules and fulfill Explosion Group IIC require-
ments. For this reason the gas analyzers can even be used in hydrogen or acety-
lene atmospheres.
The designation is
Measurement function per Directive 94/9/EC, Appendix II, Paragraph 1.5.5. is not
covered by the EC type examination certificates.
The EL6010 family includes the following analyzer units (see page 53)
• EL6010-Uras14 Infrared Analyzer Unit,
• EL6010-Magnos106 Oxygen Analyzer Unit and
• EL6010-Caldos17 Thermal Conductivity Analyzer Unit
as well as the
• EL6010-CU Control Unit (see page 54).
An EL6010 gas analyzer consists of an analyzer unit and the control unit.
