Risknowlogy certified the CALAMOT 6 of Siemens. The CALOMAT 6 is an extractive continuous gas analyser for quantitatively determining Hydrogen or Helium in digital or quasi-digital non-corrosive gas mixtures. Concentrations of other gases can also be measured if their thermal conductivities differ significantly from the residual gases, like Argon, Carbon Dioxide, Methane, or Ammonia.

The certification included:

• Functional safety management
• Safety requirements specification
• Hardware requirements
• Reliability requirements
• Software requirements
• Basic safety
• User documentation

The CALOMAT 6 achieves SIL 2 according to IEC 61508.
