KFDO601 Online Fluorescence Dissolved Oxygen No Electrolyte Is Required And Will Not Be Polarized No Oxygen Consumption
1.Dissolved oxygen measurement applications
- Food and Beverages
- The pharmaceutical
- Energy and electricity
- education
- The government
- water
- Waste water management
2.the Difference of Polarographic probe and optical probe
| Polarographic probe | optical probe | |
| maintence | Replace the electrolyte approximately every 2 months and polish the cathode as needed to clean the probe | Clean probe, cover and optical window as needed |
| storage | Stored in a wet calibration sleeve;For long-term storage, remove the film cover and store in a dry place | Store in a wet calibration sleeve |
| film | Replace approximately every 2 months as needed | no |
| solution | Replace approximately every 2 months as needed | no |
| Need to preheat | (30-60 minutes) if only connected to the meter | |
| stir | need | unnecessary |
| disturb | Ozone, sulfides, sulfur dioxide, nitrous oxide and carbon monoxide |
3.Feature
- No electrolyte is required and will not be polarized.
- No oxygen consumption, not affected by flow rate.
- Built-in temperature sensor, automatic temperature compensation.
- Free from interference by chemicals such as sulfides
- Small drift, rapid reaction, more accurate measurement.
- Long service cycle, lower cost of use.
- Simple replacement of fluorescent cap.
- Rs-485 interface, Modbus/RTU protocol.
- Low power consumption,anti-interference.
