CS6602CD Digital COD Sensor
Introduction:
COD sensor is a UV absorption COD sensor, combined with a lot of application experience, based on the original basis of a number of upgrades, not only the size is smaller, but also the original separate cleaning brush to do one, so that the installation is more convenient, with higher reliability.
It does not need reagent, no pollution, more economic and environmental protection.On-line uninterrupted water quality monitoring.Automatic compensation for turbidity interference, with automatic cleaning device, even if long-term monitoring still has excellent stability.
Testing principle:
Many organic compounds dissolved in water are absorbent to ultraviolet light. Therefore, the total amount of organic pollutants in the water can be measured by measuring the extent to which these organics absorb ultraviolet light at 254nm. -

CS6530CD Digital Dissolved Ozone Sensor
The electrode system consists of three electrodes to address issues related to the working electrode and counter electrode failing to maintain a constant electrode potential, which can lead to increased measurement errors. By incorporating a reference electrode, the three-electrode system of the residual chlorine electrode is established. This system allows for continuous adjustment of the voltage applied between the working electrode and the reference electrode by utilizing the reference electrode potential and voltage control circuit. By maintaining a constant potential difference between the working electrode and the reference electrode, this setup offers benefits such as high measurement accuracy, prolonged working life, and reduced need for frequent calibration. -

Digital sensor Fluoride Chloride Chloride Potassium Nitrate ion for wastewater sensor CS6710AD
CS6710AD digital fluoride ion sensor uses a solid membrane ion selective electrode for testing fluoride ions floating in
water, which is fast, simple, accurate and economical.
The design adopts the principle of single-chip solid ion selective electrode, with high measurement accuracy. Double salt
bridge design, longer service life.
The patented fluoride ion probe, with an internal reference fluid at a pressure of at least 100KPa (1Bar), seeps extremely
slowly from the microporous salt bridge. Such a reference system is very stable and the electrode life is longer than the ordinary. -

Digital conductivity sensor series CS3742D
Digital Conductivity Sensor: Digital Conductivity Sensor is an online instrument for continuous measurement of electrical conductivity in liquids, directly indicating total ionic concentration (salinity, TDS). It operates on a two‑ or four‑electrode design (graphite or platinum) with an 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 and supports plug‑and‑play connectivity, remote calibration, and self‑diagnostics. With a wide measurement range (0‑2000 μS/cm to 0‑2000 mS/cm) and rugged, waterproof (IP68) housing, it suits water treatment, reverse osmosis, cooling towers, aquaculture, and industrial process control. Real‑time, continuous data 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 reliable data for unattended water quality monitoring. It requires no reagents or sample preparation, making it an essential, cost‑effective tool for environmental and industrial applications.
