The DSC series intelligent conductivity digital sensor checks the conductivity of medium in steps from 0.05 μ S/cm to 200mS/cm. Only range distinction is employed; all other important factors, performance, and interfaces remain the same. It can be used to check the quality of water in the environment, to make acid-base salt solutions, to find pure water, and for other purposes. The industrial-grade architecture makes sure that the system works reliably for a long time and that media conductivity monitoring is the same at different concentrations.

Core common advantages
- Multi resolution, precise range matching: The resolution of each model is adapted to the range, and data acquisition is accurate without deviation
- Intelligent temperature compensation: built-in NTC10K, automatic compensation from 0~60 ℃, to counteract the interference of temperature on measurement
- Industrial grade communication: RS485 (Modbus/RTU) standard protocol, seamlessly integrated with PLC/DCS/multi parameter monitoring devices
- Standardized installation: 3/4 “NPT universal interface, supports top insertion/circulation/sinking/pipeline/sidewall installation in multiple ways (tilt ≥ 15 °)
- Convenient single point calibration: factory pre calibration, no frequent operation required for non deviation, calibration can be completed with standard buffer solution
Featured Applications
- Ultra pure water field: electronic grade ultra pure water, laboratory pure water, pharmaceutical purified water (choose DSC-0.01AS)
- Low concentration water bodies: drinking purified water, mineral water, surface water, reverse osmosis produced water (choose DSC-0.1AS)
- Conventional water quality: municipal tap water, swimming pool water, landscape water, domestic sewage treatment (choose DSC-1AS)
- Industrial high concentration media: chemical acid alkali salt solutions, electroplating wastewater, industrial circulating water, high salinity wastewater (choose DSC-10AS)
Installation and wiring
Installation requirements
- Supports 5 installation methods: top insertion, circulation, sinking, pipeline, and side wall. Any method must ensure that the sensor is tilted ≥ 15 °, and inverted/horizontal installation is strictly prohibited
- Installed in areas with gentle water flow, avoiding interference from turbulent water flow and bubbles. The probe should be at least 2cm away from the bottom of the container/pipeline
- Clean the probe with distilled water before installation to prevent scratching the stainless steel detection surface, fix it firmly and avoid shaking
Electrical wiring (four wire system, color coded)
- Red wire: 24VDC Power (+)
- Black wire: GND Power (-)
- White wire: RS-485A
- Blue wire: RS-485B
After the wiring is completed, it is necessary to carefully check to confirm that there is no reverse or virtual connection, in order to avoid damaging the sensor after power on; Keep the wiring connections dry to prevent moisture.
Maintenance and Care
- Daily cleaning: Clean the probe attachment every 30 days, gently wipe with a soft damp cloth, and prohibit scratching the stainless steel surface with hard objects; When scaling, it can be cleaned with detergent or 0.5g/100ml dilute hydrochloric acid/dilute nitric acid. After cleaning, rinse with distilled water
- Calibration specifications: Pre calibration has been completed at the factory, and it is not recommended to calibrate randomly if the measurement error exceeds the range; During calibration, use the corresponding range standard buffer solution, with the probe at a distance of ≥ 2cm from the bottom. After the value stabilizes (about 3 minutes), send the calibration command
- Recovery delay: After cleaning and reinstalling the probe, it may take several minutes to several hours for the data to recover to its initial accuracy, which is a normal phenomenon
- Idle disposal: When not in use for a long time, remove the probe, clean it with distilled water, wipe it dry, and store it properly to prevent scaling and corrosion of the detection surface
