Water Quality control is essential for the management of water in the environment and industry. Pollutants can wreak havoc on machinery and equipment in industrial plants and cause health problems for staff and communities. Monitoring is essential to provide the objective evidence necessary to make sound decisions on managing water quality.
This digital sensor is suitable for real-time pH value monitoring in industrial wastewater, water works, food processing, pharmaceutical, and other industries. It integrates electronic circuits and microprocessors inside the sensor.
The two-electrode online conductivity sensor uses graphite which has good test accuracy and stability. It uses RS485 communication interface, supports MODBUS protocol, and has a built-in high-precision NTC sensor to perform accurate temperature compensation for conductivity measurement in real time.
The online turbidity electrode is widely used in drinking water treatment plants, sewage treatment plants, integrated purification tanks, the paper industry, and chemical industries. The online turbidity electrode adopts a 90-degree scattered light method and uses a near-infrared light source to eliminate chromaticity interference. It meets the IS07027 standard. The beam will emit scattered light when it hits the suspended matter in the sample during transmission. The detector set at 90% of the incident light receives the scattered light, which is directly proportional to the concentration of suspended matter in the sample. Turbidity can be calculated by measuring the intensity of the scattered light.

This multifunctional water quality detection pen detects the TDS value (total dissolved solids, unit is ppm) and conductivity value (the conductivity of the solution, unit is us/cm) of water. It has a measuring range of 0~9999ppm,0-9999us/cm. It measures the purity of the water, as well as the water temperature and the environmental temperature. It is suitable for use in the water treatment industry, residences and outdoors.
This intelligent online controller is widely used in water quality detection and monitoring in sewage plants, waterworks, water stations, surface water and other industries. Its modular design offers various modules of more than 20 kinds of sensors, which can be combined at will, as well as reserved expansion functions. It can measure 4 parameters similtaneously and has 2 analogue outputs.
The UVlyser monitors Turbidity or TSS and up to 4 freely chosen wavelengths between 190 and 720 nm. The UVlyser provides cost-effective and accurate solutions for surface water, drinking water, groundwater, and wastewater applications.
This Dissolved Oxygen (DO) Monitoring and Control System is a rugged dissolved oxygen analyser which utilises a long-life, low-maintenance galvanic DO sensor. It provides the user with exactly what they need for continuous DO monitoring and control of important aeration processes. It seldom requires maintenance or recalibration. It has a backlit display and comes with a digital output, two analogue outputs, and two control relays. It is a fully-powered, continuous monitoring and control analyser. It is used in combination with a galvanic DO sensor. The galvanic sensor has a pure platinum cathode, making the sensor incapable of being poisoned by other gases often found in impure waters, such as hydrogen sulfide. It utilises DO sensing technology that is successful in continuous de-nitrification monitoring and control applications. It can be used continuously in very violent pure liquid oxygen injection systems. Complete systems are supplied with over 5 years of sensor electrolyte and membranes. When used correctly, these Teflon® membranes will last well over a year and require minimal maintenance.
The Portable Water Analyser is paired with the Turbidity Sensor, enabling convenient, accurate, and easy measurement of turbidity. It is comfortable to operate because of its ergonomic design and is available with single or dual-channel configurations.
These bio-electrode sensors (BES) allow you to reliably measure and monitor the changing BOD or VFA concentrations in wastewater. IT has a sensor biofilm which is customised to the following applications: wastewater collection networks, influent locations of wastewater treatment facilities, anaerobic selectors for biological nutrient removal, and anaerobic digestion environments. The sensors monitor biological oxidation of organic carbon in wastewater streams by measuring the rate at which in-situ and customised biofilm surfaces consume the available food. A biofilm is established on the sensor after 1-3 days in the wastewater stream. This bio-electric surface then uses the sensor current collector to generate a flow of electrons that is equivalent to the rate of organic carbon oxidation. This flow of electrons is measured and displayed on an online dashboard and updated every minute. Increasing BOD in wastewater will result in increased metabolic activity and sensor signal; acute chemical toxicity or significant dilution of BOD will result in low alert signals and reduce metabolic activity. This results in reliable, real-time insight into biological treatment rates and performance. These microbial, fuel cell-based sensors are robust and are used in the most challenging situations. Very little maintenance or cleaning is required. It highlights microbial activity variations, organic matter degradation, and process upsets, which can guide your operations.
These Conductivity/Resistivity Electrodes are designed to provide versatile installation and accurate sensing across a very broad and dynamic range. They have a controlled surface finish to ensure accuracy and repeatability. The standard electrode is constructed out of 316 SS, but there are other materials available for maximum chemical compatibility (Titanium, Monel and Hastelloy-C). Reversible threads or sanitary flanges allow for maximum installation versatility. Sanitary flange versions are available in either SS or Titanium with a quality surface finish of less than RA 25. An optional NIST Traceability Certificate (to meet USP requirements) is available. Coupled with GF Signet patented measuring circuitry, a platinum RTD (PT1000) located within the electrode allows optimal temperature sensing.
The soli::lyser is an optical probe that measures concentrations of suspended solids directly in the water. It integrates the temperature measurement for online correction. Using the principle of infrared absorbance, the readings are not affected by colors. The soli::lyser utilises an automatic cleaning system that uses compressed air for the removal of fouling. Because of this, regular manual cleaning of the optical windows is not required, thus significantly reducing maintenance for the operator. It has no replaceable parts or consumables, thereby reducing operational costs.
The level of mixed liquor suspended solids in aeration basins is an essential parameter for the process control of wastewater treatment plants. The concentration of suspended solids measured by the TSS sensor can be used for the optimisation of the biological treatment processes (i.e. nitrification, denitrification as well as phosphorus elimination) and for the control of sludge recirculation.
The redo::lyser is a stable and virtually maintenance-free ORP sensor for online measuring of the redox potential immersed in the medium or in a flow cell. Thanks to ground-breaking reference electrodes, high precision is guaranteed in virtually any medium under the harshest conditions. It is pre-calibrated ex-works and is immediately ready for use.
