ADS550 Dissolved Oxygen Analyzer
Brand: ABB GroupThe Navigator 500 dissolved oxygen analyzer provides continuous monitoring and control of dissolved oxygen levels in steam-raising and desalination plants and semiconductor water treatment.
Featuring a separate sensor section and transmitter, the Navigator 500 Dissolved Oxygen gives users the option of adding up to four wet-sections to one transmitter, enabling measurement of samples from different measuring points.
This not only offers an economic and compact solution, but allows operators to mix and match other parameters within the Navigator 500 range to reduce installation footprint and cost.
Features- Maintenance-free dissolved oxygen sensor removes the need for membrane changes or electrolyte replenishment
- Automatic calibration minimizes manual intervention and ensures accuracy
- Fast response time allows control of rapid changes in plant conditions
- Intuitive software with full color graphical display
- Data logging and graphical process trending
- Full audit trail capability
- Secure data archiving to SD Card or USB Stick
