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.

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.
Suitable for liquid low-flow or flow-failure alarm on cooling systems, water heaters or lubrication systems. This rugged sensor has a simple electrical reed switch output. Installed in a vertical line with flow upwards, the normal flow lifts the float in the sensor. A magnet encapsulated in the float then actuates a reed switch, giving contact closure. Should the flow drop to below the preset alarm level, the float falls to the rest position and the contacts open to give an alarm output. Available in 1/2” and 3/4” line sizes, with BSP female threaded connections. Alarm rates are factory set between 0.5 L/min and 10 L/min to suit most applications. The standard unit is brass and has a one-piece body suitable for high pressures, with no glands or seals to leak. The externally mounted reed switch has flying leads for local connection to a terminal block. Typical applications include water supply flow failure into heaters or boilers (where the flame or power supply is cut to prevent overheating accidents), for lubricant or cutting fluid flow failure in machine tools or gearboxes. For flow failure alarm in cooling circuits, the LF flowswitch is used on X-ray equipment, electron microscopes, transformers, radio transmitters and high frequency generators.
This rugged, high-performance radar level measurement sensor has a transducer and processing electronics incorporated in one. It is suitable for single and multiple-tank applications. 2-wire sensors are recommended using either HART protocol or 4 to 20 mA for direct communication with a panel mount controller or a PLC. This is used for liquid level measurement in sumps or tanks, for tank volume measurement, or open channel flow measurement. Sensing ranges up to 20 m (66 ft) are available. PP and PVDF sensor bodies provide the best chemical resistance in applications where concentrated chemicals need to be detected. Applications include Water Treatment, Corrosive Industrial Waste Treatment, Filling, Batching, Bulk Transfer, and Dirty Liquids.
This non-contact radar level transmitter uses 80 GHz FMCW radar. The key advantages of 80 GHz technology are a smaller antenna size, improved focusing capability, and a narrower beam angle. This can be used to measure liquids, bulk solids, emulsions, and chemicals across the water, food, energy, pharmaceutical, and chemical industries, delivering millimetre-accurate results. This is also well suited for liquids with a gas blanket, vapour-prone substances, and large-particle bulk solids. This includes open-channel flow measurement and has threshold functions to suppress false and interfering echoes. The transmitter can also operate in a vacuum. The device can also be used with HART® compliant NIVELCO EView2, MultiCONT universal process controller, MonoCONT smart field display & data logger, and PACTware™ software, or configured via Bluetooth® communication using the MobileEView application.

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.
