Chemical Residual Transmitter

Detect chlorine dioxide and hypochlorite residual for effective dosage of bleaching chemicals

The RT-5500 measures chemical bleach residual, particularly residual chlorine dioxide and hypochlorite. The transmitter is an integral part of the process control to accurately and cost effectively dose bleaching chemicals in modern bleach plants.

  • Continuous measurement of chemical residual
  • Integrated with pulp brightness measurement for process control
  • Accurate and cost effective dosage of bleach chemicals
