Measuring chlorine dioxide for bleaching in pulp mills - May 2004 - Automation Control Solutions - SA Instrumentation & Control
Source: Automation Control Solutions. Rosemount Instruments' Models 54e pH/ORP and 3081 pH/ORP are suitable instruments for monitoring and controlling pH and ORP in pulp and paper mills
{for paper mills} "Due to the very aggressive nature of the process stream, all wetted parts are manufactured from corrosion resistant materials, such as titanium and sapphire. Integrated dual channel reference detectors compensate for all possible disturbances such as varying levels of particulates (turbidity) and lamp aging." "Split-beam technology compensates for lamp aging and varying particulate levels including bubbles.
The signals from other instruments measuring temperature and/or pressure are recommended to be used directly as compensation for the raw
gaseous ClO2 concentration"

What do I use to calibrate my Chlorine Dioxide (ClO2) or Ozone (O3) BW or RAE Portable Gas Detector?
"There is no compressed ozone or chlorine dioxide gas available for calibrating these instruments. End users can have the unit calibrated by any of our Distributor Service Centers or send their units to us through a distributor to be calibrated, or can purchase a calibration gas generator for ozone or ClO2 in order to calibrate and bump test their instruments"
