Water/Wastewater 35 Spectrometry for the People
In 1999, the world’s first submersible UVVis spectrometer was introduced by s::can liquid monitoring systems, Vienna, Austria. Since then, s::can (Austria) has become the world market leader in online spectrometry: World wide, more than 700 applications from drinking water to industrial waste water have been put into practise. Today, s::can (Austria) is able to offer a full range of
online instruments (“smart sensors”), most of them optical, all insitu and at zero regular maintenance. COD, TOC, DOC, BOD, UV254, SAC, NO3, NO2, NH4, TSS, FTU/NTU, BTX, Phenols, optical O2, pH, Redox, Conductivity, Contaminant Alarm. All sensors can be operated from the same controller terminal, and all are integrated via a digital bus. The user interface is uniform for all sensors which makes communication, operation and calibration straightforward and simple. Thus, the fixed and operational costs are kept at an unmatched low level and the maintenance costs are negligible.
s::can optical instruments are now available at different levels of price and performance, thus systems can be designed compatible to almost any budget, from small wells up to full size
treatment plants. A system consisting of one con::lyte terminal together with a single parameter measurement, i.e. for control of NO3 in the aeration tank, will be as cost efficient as a full system consisting of many sensors and terminals. s::can optical instruments are extremely robust, versatile and drift free for months. No chemicals, no membranes, no moving parts are in contact with the medium. For waste water applications a most efficient pressure air cleaning system keeps the sensor free of dirt, fat or even silicone grease. Internal dataloggers and most comprehensive process visualisation software are standard. Plug-and-play? Within just 2 minutes from unpacking, the first concentration readings are displayed. Online spectrometry confined to the > 10.000 budget? This is history. The instruments of s::can´s brand new Gcompact series are works-calibrated multiparameter probes, and cost-compatible even for smallest plants and budgets. References given by s::can include drinking water alarm systems, surface and ground water monitoring systems, waste water and sewer system monitoring and industrial waste waters.

Safe and Eco-Friendly Analysis of Industrial Water
Levelogger Proven to be Worth its Weight in Gold
When it comes to industrial wastewater analysis, your testing materials must be tested as rigorously as the wastewater itself, and that’s exactly how Merck (Germany) designed their Spectroquant®
test kits. Many Spectroquant® analysis methods
conform with international standards and are thus comparable with references. All Spectroquant®
analysis methods are
validated. Validation data are registered for each single Spectroquant®
recorded in the validation document.
One of their greatest goals is to reduce the amounts of hazardous or toxic chemicals in our test kits. Some examples Nitrate test: the 2.6 dimethylphenol method is cadmium-free and non-carcinogenic; Lead test: chloroform- free extraction, and Anionic surfactants test: avoids direct exposure to chemicals due to pre-sealed, benzene-free extraction.
What’s more, Spectroquant® comes with
comprehensive information on disposal and waste management issues.
Cell test kits
The characteristic feature of the Spectroquant®
cell test kits is their high user-
friendliness. Virtually all of the reagents necessary for the analysis are contained in cells. When you insert your cell into a Spectroquant®
NOVA or Pharo photometer,
the bar-code on the cells make the instruments automatically select the correct method of analysis.
Reagent test kits Spectroquant®
STS Gold Telemetry Systems
reagent test kits contain highly
stable, ready-to-use reagent mixtures. Selection of the appropriate cell format makes it easy to vary the measuring range as you require. We check the linearity of the calibration function for all cell formats. Each pack contains an AutoSelector that gives the bar-code for the selection of the correct method in the photometer.
Spectroquant® test kits can be used in
conjunction with all spectrophotometers and also with photometers from other suppliers.

Mandate to Deliver Quality
Since the Levelogger Gold was launched at the beginning of 2006, Solinst has shipped thousands and thousands of units to satisfied customers all over the world.
The Levelogger Gold is a self contained water level datalogger, which is completely designed, developed and manufactured in-house, in the tradition of all Solinst high quality products. The Levelogger Gold uses infra-red data transfer, providing the flexibility of installing by use of a simple wireline or by using a Direct Read Cable to surface. The Levelogger Gold includes a pressure transducer, temperature thermistor, 10 year lithium battery (based on 1 reading per minute), and internal datalogger with a capacity of 40,000 temperature and water level datapoints.
“Our mandate is to design and deliver high quality products, and back it up with our 3 Year Warranty, demonstrating the Solinst commitment to our customers.”
— Sarah Belshaw, President
Dependable Water Level Datalogger • Maintenance Free Design/Lifetime Calibration • 3 Year Warranty • Real-Time View • User-selectable Sampling Schedule • 10 Year Battery (1 reading/minute) • SDI-12 Compatible
RRL Gold Remote Radio Link
The RRL Gold System offers a very simple and inexpensive method of local telemetry. The compact, all-in one design allows discrete placement in the field. Using short-distance radio, the RRL is excellent for creating small, closed loop monitoring networks with Leveloggers. Ideal for mine sites, golf courses, or landfill monitoring.
