SICK’s ZIRKOR200 gas analyzer provides very robust, reliable, and suitability-tested oxygen measurement for small and large combustion plants.

The ZIRKOR200 is characterized by a measurement cell with a particularly long service life.

The long-life technology employed for this purpose increases the resistance of the measurement cell in corrosive and reducing conditions in particular.

The integrated measurement cell monitoring system and fully automated adjustment significantly reduce the maintenance effort.

The ZIRKOR remote app allows you to wirelessly access the analyzer quickly and easily.

The ZIRKOR200 provides a low-maintenance, simple oxygen measurement system for incineration optimization.

Thanks to its suitability test as per EN 15267, it is also suitable for emission monitoring.
  • Very high availability due to electrochemical cell with extremely long service life
  • High reliability due to innovative measurement cell protection – even in corrosive or reducing conditions
  • Reduction in analyzer failures because of internal self-monitoring
  • No manual adjustment required
  • Quick measurement close to the combustion process for timely control
  • Approved for emission monitoring
  • Easy analyzer operation – including remotely
