LAR have improved and further developed the proven Total Organic Carbon (TOC) analyzer with UV persulfate oxidation –LAR QuickTOCuv.

The new LAR QuickTOCuv II is state of the art and has more great features. In addition to a slim design and an IP65 housing, the new online TOC/ TC analyzer can also determine COD and BOD values using correlation factors.

The measuring ranges can be adjusted by individual user input with the measurement system is controlled by a user-friendly 4″ PLC with touch screen.

LAR QuickTOCuv II Analyser is ideal for fast and reliable online monitoring in pure, drinking, surface and waste water.
