IR 'C' Range

Suspended Solids Sensors for Environmental Research

The IR 'C' version of Partech's trusted range of infrared based Suspended Solids and Turbidity sensors is aimed at applications in the environmental monitoring and research fields. It has been specifically developed to work with a wide range of data logging devices that are in common used in universities and research organisations. The sensor produces an output signal that can be calibrated either within the logger or via a spreadsheet to provide a linear response to the actual solids present in the water being monitored.

The sensors have provided data for a multitude of academic papers in applications from Glacial Streams in the Alps, through Tropical Rainforest Rivers in Borneo to Melt Water in Greenland and sediment transport in the Humber Estuary. Many theses and doctoral reports have been produced used the IR 'C' sensors.

Being exceptionally easy to deploy and having a very low power consumption there are no hidden costs to the purchase of these sensors. Partech are happy to put together a monitoring package including a logger, power source and weatherproof enclosure. These packages will allow data to be retrieved without visiting the site, keeping project costs down and allowing measurements over wide areas.
