The D700 and D800 series online optical digital dissolved oxygen sensor with fluorescence technology without membrane and electrolyte. The cap of the sensor is coated with luminescent material. The sensor applies NTC temperature compensation and direct digital signal output. The D700 and D800 are completed with RS485 (modbus) digital signal output, integrating and networking with the IUNI-21 dual channel analyzer.
The IUNI-21 dual channel analyzer is an effective option that can connect two digital dissolved oxygen (DO) sensors at the same time to reduce the cost of transmitter and installation space:
- Field mounted dual channel analyzer with datalogger
- Connect two sensors at one time
- 4-20mA output
- Relay output
- Communication, RS485 (Modbus)
- LCD visual display
- User-friendly and attractive operating interface
Price is indicative, consisting of 1 x IUNI-21 Universal Transmitter and 1 x D700 Digital Dissolved Oxygen Sensor.
