Standard Configuration
- Host:A11CL-AA1-LOW
- Residual chlorine electrode: TS-238-10M
- Electrode flow channel: PP-67
Core Highlights
- Designed for precise monitoring in low concentration settings (0-2 mg/L) with ± 0.01 mg/L accuracy and consistent data without drift.
- Multi-temperature compensation adaptation: It supports PT1000, NTC10K automatic, and manual temperature compensation from 0-100 °C for diverse operating conditions.
- Isolation technique protects 4-20mA output from electromagnetic interference in industrial applications, ensuring reliable signal transmission.
- High and low point alerts can be freely regulated with three sets of relays with adjustable hysteresis to prevent frequent on-off. Automatic connection cleaning by the integrated electrode reduces maintenance costs.
Featured Applications
- Check the chlorine level in the plant and pipeline water to make sure it is safe. This can be done with a municipal or backup water source.
- Pharmaceutical business: To make sure the end product is good, any chlorine that might still be in the process water for the pharmaceutical business needs to be tested.
- So that food stays safe and water quality rules are met, cut down on the chlorine in the water that is used to clean and prepare food.
- Monitoring low-chlorine flowing water in the chemical industry to keep machines from breaking down and production from being held up.
- After cleaning, keep an eye on the low chlorine level to make sure the environment is safe and stop secondary contamination.
Daily maintenance and precautions
Installation and usage precautions
- Installation: Use a panel with a 92 × 92mm opening to prevent exposure to extreme temperatures, humidity, corrosive conditions, and direct sunlight.
- Electrode installation: The electrode is fixed with PG13.5 threads, and when used with a flow channel, the inlet and outlet water pipelines must be unobstructed (compatible with 9.5mm pipes).Signal transmission requires special cables that cannot be replaced with ordinary wires.
- Wiring: To reduce interference from dosing and mixers, use a separate power source. When the instrument interface is hooked up to other devices, it needs to be protected by a relay that can handle current.
- For slope calibration, a steady water sample is injected for 15 minutes and modified according to laboratory results. Zero calibration requires pure water without chlorine.Electrodes must be cleaned and wiped dry before calibration to ensure membrane cleanliness.
- The default password is 0000. To prevent non-professionals from mistakenly operating important parameters, update the password after use.
Key daily maintenance points
- Instrument maintenance: Regularly clean the instrument casing to avoid contact with organic solvents such as toluene and xylene; Before long-term use, it is necessary to restore the factory settings and cut off the power, and store it properly.
- Electrode maintenance: The electrode needs to be regularly cleaned of the membrane to avoid contamination affecting the measurement; The electrolyte should be replaced regularly (according to the usage frequency of 2 weeks to 2 months), and the membrane should be replaced promptly if it is damaged.
- Calibration cycle: It is recommended to perform zero point and slope calibration once a month. For scenarios with large temperature fluctuations or complex water quality, it can be shortened to once every two weeks.
- Whether the signal output isn’t normal, check to see whether the cable is broken or the wiring is loose. Before recording data drift, make sure to calibrate or check the status of the electrode.
