Applications- Trace oxygen monitoring in pure water processes Advantages
- First luminescent sensor for process ppb level oxygen monitoring
- Traceable fully automatic in-situ calibration
- Low cost of ownership: downtime reduced to 5 minutes annual service
- Dry sensor: no electrolyte, no chemicals, and no membrane
- Perfectly suited for OT and AVT, including plants working shifts: oxygen levels do not affect service intervals - Simple to install and operate.
