Single Point Kappa

A kappa number analyzer mounted directly to the pulp processing line

The SPK-5500, Singe Point Kappa Number Analyzer, measures continuously the kappa number of pulp suspensions. In contrary to common multi-point kappa analyzers, it is much smaller and mounted directly to the pulp processing pipeline and therefore provides kappa number results at a high frequency.

  • Continuous kappa measurement at optimum sampling points
  • Accurate kappa results at high frequency allowing enhanced process control
  • Low costs of installation and ownership
  • Costly auxiliaries such as remote pulp samples, water valves and transport lines become redundant

  • High availability, robust system with little auxiliaries
  • Easy calibration with long term stability
  • Improved process control in bleaching an pulping operations
  • Lower installation and operational costs


System requirements
The analyzer is intended for inline installations and use at ambient temperatures of maximum 50 °C (122 °F), flow velocity of 0.3 – 6 m/s and a process pH of 2 – 14. The SPK-5500 is mounted directly to the pipeline. It is rated for voltages of 100 – 240 VAC at 50 Hz / 60 Hz.

Sample Specification
Sample temperatures up to 120 °C (248 °F) with consistencies of 2 – 16% depending on pulp type.
