UV-106-W Aqueous Ozone Monitor

UV-106-W Aqueous Ozone Monitor will measure dissolved ozone in water from 0-100 ppm with 0.1ppm resolution.  Ozone is measured by sparging ~2 mL of water and integrating the gas-phase concentration of ozone stripped from solution with high precision and accuracy.

Ozone Information


The UV-106-W is an Aqueous Ozone Monitor to measure dissolved ozone in water with high precision and accuracy.  For testing, dissolved ozone is measured by sparing ~2 Ml of water with ozone-scrubbed ambient air and integrating the gas phase concentration of ozone stripped from solution.  Because ozone is measured in the gas phase, interferences from particles and dissolved inorganic and organic compounds are removed, allow you to use this instrument in both ultrapure and "dirty" water applications.

Ozone levels are measured at 0-100 ppm with a resolution of 0.1ppm.  The sample water flow range can be 50-1,000 mL/minute and has analog and digital outputs.



  • Interference free measurement of dissolved ozone in ultrapure or "dirty" water
  • NEMA water-proof housing
  • Records measurement every 10 seconds
  • Internal data logger logs 16,383 lines of data
  • Precision and accuracy of 0.05 ppm or 1% of reading
  • Both serial and user-scalable analog outputs (0-2.5V and 4-20mA)
  • Selectable data averaging times of 10 seconds, 1 minute, 5 minutes, and 1 hour
  • LED alarms
