Professional Tengine Trace Dissolved Oxygen Analyzer / Meter - MDO10AC For Power Plant
1. Application
Used for trace dissolved oxygen ( ppb ) measurement
• Power plant
• Semiconductor industry
• Pharmaceutical industry
• Food industry
2. Features and Benefits
• Based on the innovative principle of utilizing fluorescence to measure dissolved oxygen,no need to replace membranes and only low-maintenance needed.
• No oxygen consuming during operating , do not need stir or flow.
• Digital sensor has good anti-interference performance and high stability, and the cable length is available in hundreds of meters.
• “plug and play” sensor, and dual-channel transmitter • operates either 1 or 2 sensors.
• Modbus RS485/RS232 or Profibus DP network connection for data transmission is Optional
• 3 Relays with programmable hysteresis provide high-limit alarm, low-limit alarm or timer.
• A built-in data logger with the capacity to store data for up to 10 years
