  • Produces accurate Ozone levels down to 2 ppb and meets the latest US EPA requirements for Trace-level Ozone gas instruments
  • With an interference-free Ozone measurement and best available lower detection limit (LDL) of < 0.3 ppb, the T753U performance is proven by the most sensitive Ozone gas analyzer technology available
  • Flow adjustable from 2 to 5 lpm with internal zero air source or 2 to 15 lpm with external zero air source
  • User friendly color graphics display with touch screen interface. Front panel USB Ports for easy firmware upgrades.
