Digital Online Industrial Precision TEC Dissolved Oxygen Meter / Analyzer - EDO10AC
1. Application
Monitoring of dissolved oxygen,especially in municipal wastewater and industrial wastewater treatment plants.
• Water/wastewater treatment
Aeration tank
• Surface water
Rivers,Lakes/Streams, seawater, fishing grounds
2. Features and Benefits
• User-friendly.
• Large LCD screen with backlit.
• Indicate dissolved oxygen and the temperature values at the same time.
• All kinds of data has password protection to avoid misoperation.
• Polarographic oxygen electrodes with stable performance and reliable measurement
• The electrode zero is stable with small drift.
• The electrode respond fast (up to 98% <60 s)
• Historical curve function: the measurement data is collected every 5 minutes, one month data can be stored.
• Notepad function, provides the record of operating and alarming time.
• When the electrode is calibrated, the mode, time and results are recorded, easy to review and analysis the change.
