YSI Webinar | How pH and ORP Sensors Work

September 24, 2019
The pH of a water body can affect nearly all aquatic life in a system, and the oxidative-reductive potential is a related, but underappreciated parameter particularly in environmental and wastewater applications.
  • Reasons to measure both pH and ORP,
  • The principles of operation of Ion Selective Electrodes (ISEs) as they’ve been adapted from the laboratory to the field,
  • Best practices for maintaining and troubleshooting measurements, and
  • Real-world practice to demonstrate both the value and limitations of field-deployed pH and ORP sensors.
