spectro::lyser V3

Realise the power of online UV-Vis spectrophotometers for water quality monitoring with the V3 s::can spectro::lyser

light. speed ahead.

A fully submersible online water quality sensor for drinking water and wastewater analysis. Achieve process control or compliance whatever your needs.

s::can specialise in online UV-Vis spectroscopy for water quality monitoring. Utilising the power of chemistry to derive large amounts of information about water quality, whether drinking water or wastewater from the UV-Vis spectrum. s::can’s proprietory algorithms for turbidity compensation set them apart from other online sensors. By measuring turbidity at multiple wavelengths across the spectrum, only s::can sensors can measure accurately even in spates and other highly turbid applications.

The latest generation in UV-Vis spectrophotometers.

The graph below shows the effect of turbidity on the UV-Vis spectrum. Only by being able to compensate effectively for turbidity at all wavelengths can true accuracy for UV254, true colour and more be achieved.

The next generation

Intelligent IoT enabled online UV-Vis spectrophotometer with integrated webserver for smart water quality monitoring.

Multiparameter monitoring in a flash. Choose the parameters you want to measure for your application from any that can be derived from the UV-Vis spectrum.

Drinking Water

In drinking water applications, use the V3 s::can spectro::lyser for UV254, colour, nitrate, DOC, TOC, BTX, turbidity and of course use the full UV-Vis spectrum for event detection. The spectro::lyser is ideal for raw water coagulation control applications and catchment monitoring.


Create your own monitoring station by pairing your optical spectro::lyser sensor with a s::can sensor for other parameters such as pH, conductivity, fluoride and more.


In wastewater applications, utilise the V3 s::can spectro::lyser for COD, BOD, TOC, nitrate, nitrite, hydrogen sulphide (H2S), total suspended solids (TSS) and of course use the full UV-Vis spectrum. The spectro::lyser is ideal for inlet monitoring, aeration tanks and effluent compliance applications.


Combine your optical spectro::lyser sensor with a s::can sensor for additional parameters including ammonium, pH and dissolved oxygen (DO).

Industrial Process Control

In industrial applications, utilise the V3 s::can spectro::lyser for ozone, COD, BOD, TOC, nitrate, nitrite, total suspended solids (TSS) and of course use the full UV-Vis spectrum. The spectro::lyser is ideal for process control, disinfection monitoring and effluent monitoring.


Monitor more than optical parameters with a s::can sensor for physical parameters including conductivity and pH.

The perfect measuring range and accuracy for every application

The spectro::lyser V3 is available with three different optical path lengths.
