i::scan combines the high performance of a multi wavelength spectrophotometer with even lower costs than of simple photometers! The brand new i::scan – compact, precise robust and very affordable!

The i::scan can be purchased with a 35mm & 5mm path length for all your drinking water and waste water needs.


i::scan – the new miniature multi-parameter spectrophotometer probe will revolutionize online water quality monitoring. From very cost sensitive applications down to highly resolved Smart Water Grids, in small unmanned plants, or even in single building protection.
