i::scan multiparameter spectrophotometer probe

The i::scan is a miniature multiparameter spectrophotometer probe for online water quality monitoring. With the ability to measure parameters such as colour, turbidity, DOC, UV254, TOC and COD, the product can be mounted in-line under pressure, flow through or immersion.

Depending on the water quality, the measurement windows of the unit need to be cleaned from time to time. This can be done automatically either by connecting pressurised air (in wastewater) or via a rotating brush (in clean waters).

The product is robust, using a high-tech polymer (PEEK) enclosure, sapphire windows and leak-resistant seals. It can be exposed to challenging waters including sea water, and due to its low power consumption it can be powered by solar panels or batteries.

Organic carbons are important to evaluate for water quality. Parameters like COD or DOC are an important part of the picture with respect to organic substrate, nutrition, pollution and treatability. In many cases, the interesting portion of the organics will be present in the dissolved form, thus invisible for a turbidity sensor. A spectrometric DOC sensor like the i::scan, however, responds to most of these organics, from wastewater to finished drinking water.
