which is accredited by the French Ministry of Health to evaluate, test and certify materials and products which are in contact with water intended for human consumption. The Attestation de Conformité Sanitaire (ACS) is the Certificate of Sanitary Conformity that ensures all materials used in a product and in contact with water are safe.
pipe::scan installation in a suburb of Beijing
The sensors in the pipe::scan are well known, reliable s::can sensors which have been on the market for many years. What’s unique about these sensors is that they are fully pressure- resistant: the i::scan - an optical miniature spectrophotometer with LED technology and automatic brush cleaning for the measurement of organics (TOC, DOC, UV254, UVT), turbidity and colour, the chlori::lyser – the only pressure- resistant amperometric sensor for detection of
free chlorine on the market, the pH::lyser - a very robust pH sensor without salt bridge with a polymer reference electrode, the condu::lyser - a maintenance-free 4-electrode conductivity sensor with an integrated temperature sensor suitable for industrial use, and a miniature pressure sensor. All these sensors are optimized for the use in pressurized pipes, are characterized by extremely low maintenance requirements and have been used for years in drinking water applications all over the world.
A filter in the inlet ensures that no large particles penetrate into the flow cell and a ventilation valve ensures an air free measuring environment inside the cell. Optionally, the system can automatically clean this filter and automatically take samples in case of an alarm.
The water quality data can be sent to any central database via almost any protocol using the s::can terminal con::cube, and the stations can be reached at any time in real time via VPN connection and are 100% remote controllable. Due to its low power consumption, this terminal fits the requirements for operation in decentralized installation sites.
Water is sent continuously for 24 hours in the pipe network, the turbidity value changes according to the regular fluctuation of water consumption.
Benefits at a glance:
- Real-time monitoring of different parameters– so that changes in water quality can be detected timely, speed up the maintenance response time and improve network reliability.
- Understanding of the water quality changes of the entire water supply network, based on historical and actual readings.
- Total chlorine monitoring in the pipe network not only determines the multiplication activities of microorganisms in water quality, but also controls the process operation of water systems, effectively controls the amount of added chlorine and reduces the formation of disinfection by-products.
The pipe::scan is a sensor system for monitoring drink- ing water quality in pipes under pressure
- Manual maintenance is extremely low, except regular manual sampling comparison and calibration.
- Achievement of continuous monitoring with insertion installation, no discharge and pollution, which leads to water savings.
Yanyang Hou, Manager at Beijing Clean water Co., Ltd., states: “The pipe::scan measures total chlorine/free chlorine, color, turbidity, pH, conductivity and temperature in one system. Other organic pollution parameters like TOC, DOC, UV254 can be added. After more than 6 months of testing, the equipment is running stable, the measurement is reliable and there is a super long maintenance cycle. These new devices increase the possibility of large-scale monitoring networks in the supply system.”
Water is sent continuously for 24 hours in the pipe network, the turbidity value changes according to the regular fluctuation of water consumption.
This project will be extended to many pipe::scan locations. Author Contact Details: s::can GmbH • Address: Brigittagasse 22-24, 1200 Vienna, Austria • Tel: +43 1219 73930 • Email:

Precise, durable and versatile – Spectrophotometer NANOCOLOR®
Powder Pillows and spectrophotometer NANOCOLOR® and laboratory-based water and wastewater analysis.
Precise: MACHEREY-NAGEL launches the first real icon-based touch screen spectrophotometer for mobile water analysis and your daily laboratory work with the new spectrophotometer NANOCOLOR®
Advance. It combines premium high-tech optics with outstanding usability. With it`s intuitive, icon-based menu
guidance, this innovative spectrophotometer can be used like a smartphone or tablet. The clearly arranged, high-resolution 5” touch screen display makes your daily measurement routine a real pleasure. On the technical side, the NANOCOLOR® all MACHEREY-NAGEL spectrophotometers, the NANOCOLOR®
Advance also features an integrated nephelometric turbidity (NTU) measurement function. An
advantage of this measurement is the integrated NTU-Check function, which allows the detection of interfering turbidities with every powder pillow measurement – an unprecedented measurement safety in the field of powder pillow reagents.
Durable: VISOCOLOR® Powder Pillows for chlorine and other parameters combine easy dosing of reagents with long-term stability. Every powder pillow contains the
exact amount of reagent, which is needed for one determination. No contamination of reagents is possible. Therefore, the shelf life of reagent kits is up to five years. All necessary information for quality assurance, as test name, LOT and expiry date is printed on every powder pillow to ensure the highest measurement safety. No scissor or spoon is required for opening and dosing of powder pillow reagents directly into the test tubes. This means maximum measurement-convenience for mobile and laboratory-based water analysis. The spectrophotometer NANOCOLOR®
Advance is the perfect companion for VISOCOLOR® Powder Pillows are available for many different parameters, which are important in drinking water, wastewater and water analysis in general.
Available parameters: Ammonium, Chlorine free, Chlorine total, Iron, Nitrate, Nitrite, Ozone, Silica, Sulfate, pH and Phosphate. All VISOCOLOR®
Powder Pillow parameters are preprogrammed on the NANOCOLOR® Advance impresses with clever mechanics and optics. As a unique aspect of
MACHEREY-NAGEL’s proven product range of powder pillow reagents is now also available on our new spectrophotometer NANOCOLOR® combination of VISOCOLOR®
Advance and VISOCOLOR® Advance. The
Powder Pillows Advance is a precise, durable and versatile match for optimal results in mobile
Powder Pillows. It is water and dust-proof according to IP 67 and
withstands the vibration test according to Military Standard 810H (only 514.8 Cat. 4). This underlines the robustness of the device and confirms its suitability for mobile analysis. Easy: VISOCOLOR®
Advance. All methods have prestored blank values and therefore, do not require a blank measurement, which is timesaving.
Easy to understand pictograms and written instructions in seven different languages are available for all powder pillow parameters. The NANOCOLOR®
10, 20, 40 and 50 mm standard cells, as well as 16 and 24 mm test tubes. Therefore, the NANOCOLOR® MACHEREY-NAGEL test kits from the VISOCOLOR®
and NANOCOLOR®
