Standard Configuration
- Host:A20CD conductivity controller
- Conductive electrode:KS1-5M-NTC
Core Highlights
- Dual installation mode flexible adaptation: supports panel installation and wall mounted installation. Panel installation requires a reserved 138 × 138mm hole, while wall mounted installation is fixed with 4 M5 screws to adapt to different installation environments.
- Multi mode temperature compensation and anti-interference: Supports PT1000, NTC10K automatic temperature compensation and manual compensation, 4-20mA output adopts isolation technology, strong anti-interference ability, and maximum load of 500 Ω.
- lexible output and alarm control: comes standard with a set of 4-20mA outputs, and two sets of outputs or RS485 communication can be selected as needed; Two sets of relays support multiple alarm modes such as high and low points, within/outside the interval, etc. The hysteresis can be freely adjusted to avoid frequent on-off.
- Convenient operation and security protection: supports switching between Chinese and English interfaces, clear menu prompts, and password management function to prevent non professionals from accidentally operating; The electrode signal transmission adopts dedicated coaxial cables, independent wiring to avoid interference, and the equipment is adapted to complex industrial environments.
Featured Applications
- For safety reasons, check the electrical resistivity (TDS) of both tap water and industrial pure water. This will also make sure that the water source is safe and that the pure water meets production standards.
- In the chemical production industry, it’s important to keep an eye on the conductivity and salinity of reaction liquids and circulating water in real time. Process parameters must also be controlled, and water quality issues must be avoided at all costs so that the product or equipment doesn’t suffer.
- Keeping an eye on industry processes: Good for keeping an eye on the quality of water in fields like power, electroplating, and medicines, and for helping to oversee the manufacturing process by giving information.
- Environmental monitoring: Always checking the salinity and conductivity of public water and industrial waste to help find pollution sources and get a sense of how bad the environment is.
Installation and operation points
- You can put the unit on a panel with a 138x138mm hole or on the wall using four M5 screws. Keep it out of places with high or low temperatures, a lot of moisture, or rust.
- There should be no bubbles in the water around the electrode, and it should be facing the flow of water. The wires should also be away from power lines.
- When you change the electrode coefficient, use a standard solution, like 1413μS/cm, to measure.
- You can choose how loud the alarms are and what the 4-20mA range is. Clean the electrode often with water that has already been cleaned.
