Integrated pH Measurement for Automatic Calculation of Free Chlorine at Changing pH Levels
- Wide measuring range:0.01 to 5.00 ppm.
- Low drift: < 1% during 1 month.
- Fast response: 90% of change within 60 seconds.
- Maintenance-free self-cleaning 3-electrode-system.
- Monitoring of sample flow and cleaning efficiency.
- Automatic compensation of sample pH (on-line or off-line).
- 'Built-in PID controllers as relays or continuous mA output.
- Fieldbus interface including Profibus DP and Modbus protocols
- Complete panel mounted system; tested, calibrated and ready for operation.
