CS3742D Conductivity Sensor
conductivity sensor is an analytical device for measuring the electrical conductivity of a liquid, which directly reflects its total ion concentration and purity. It operates on the principle of applying an alternating voltage between two or four electrode rings (typically made of graphite or platinum) to prevent polarization. The sensor includes a built‑in temperature sensor for automatic temperature compensation (ATC), ensuring accurate readings across varying temperatures. Conductivity sensors are widely used in water treatment (e.g., reverse osmosis, boiler feedwater), industrial process control, aquaculture, hydroponics, and environmental monitoring. They can measure from ultra‑pure water (0.055 µS/cm) to high‑concentration brines (up to 2000 mS/cm). Output options include 4‑20 mA, RS‑485 (Modbus), or digital protocols, enabling seamless integration into SCADA or IoT platforms. The sensor is housed in a durable, waterproof (IP68) body with anti‑fouling materials. Regular calibration ensures long‑term stability. By delivering real‑time conductivity data, the sensor helps operators optimize chemical dosing, monitor product quality, protect equipment from corrosion or scaling, and ensure regulatory compliance. It is an essential, cost‑effective tool for continuous, unattended water quality monitoring in both industrial and environmental applications. -
CS3740D Digital Conductivity Electrode
Digital Conductivity Electrode is an online sensor for measuring the electrical conductivity of a solution, which directly indicates its total ionic concentration. It operates using a two‑ or four‑electrode design (graphite or platinum) with an applied alternating current to prevent polarization. The sensor features a built‑in temperature sensor for automatic temperature compensation (ATC) and directly outputs calibrated readings in μS/cm or mS/cm via RS‑485 (Modbus RTU). Its digital output eliminates signal errors common in analog sensors and supports plug‑and‑play connectivity, remote calibration, and self‑diagnostics. The electrode has a wide measurement range (e.g., 0‑2000 μS/cm to 0‑2000 mS/cm) and a rugged, waterproof (IP68) housing for long‑term stability in harsh environments. Typical applications include water treatment, reverse osmosis, cooling towers, chemical process control, aquaculture, and environmental monitoring. The digital conductivity electrode requires no reagent, no sample preparation, and provides real‑time, continuous data. It helps optimize chemical dosing, protect equipment from scaling or corrosion, ensure product quality, and maintain regulatory compliance. Compared to analog sensors, the digital version simplifies system integration, reduces maintenance, and provides more reliable data for unattended, continuous water quality monitoring in industrial, municipal, and environmental applications. -

For example, monitoring and control of raw water and water quality of water production equipment such as recharge water, saturated water, condensate water and furnace water, ion exchange, reverse osmosis EDL,seawater distillation 。Digital Salinity Meter is an online analytical device for continuous measurement of salinity in water, typically expressed in practical salinity units (PSU), parts per thousand (ppt), or mg/L (ppm). It operates by measuring electrical conductivity (µS/cm or mS/cm) and converting the value to salinity using a built‑in algorithm and automatic temperature compensation (ATC), ensuring accurate readings over a wide temperature range (e.g., 0–60°C). The sensor directly outputs measurement data via RS‑485 (Modbus RTU) or 4–20 mA, enabling plug‑and‑play integration into SCADA or IoT monitoring platforms. It features a rugged, waterproof (IP68) housing, fast response, and low maintenance. Typical applications include seawater monitoring, aquaculture (fish/shrimp farming to control osmotic stress), ballast water treatment, industrial wastewater, desalination plant feedwater and brine monitoring, and agricultural drainage. Measurement ranges typically cover 0–70 PSU (or 0–70000 mg/L). Unlike traditional refractometers or hydrometers, the digital sensor provides real‑time, continuous data without manual sampling or laboratory analysis. By delivering continuous, reliable salinity readings, the digital salinity meter helps optimize irrigation, protect aquatic life, ensure discharge compliance, and reduce operational and maintenance costs. Its plug‑and‑play design makes it an essential tool for both field and industrial water quality monitoring. -
