LAR TOC Analyzer : QuickTOC uv

QuickTOCuv™ is an online measurement system for the determination of total organic carbon (TOC) and the dissolved organic carbon (DOC) in pure, drinking, surface and wastewater.

LAR’s QuickTOCuv is an online TOC analyzer for the continuous determination of total carbon (TC), total organic carbon (TOC), non-purgable organic carbon (NPOC), and dissolved organic carbon (DOC) in solid-free water such as pure, drinking, surface and process water.

The process control has been optimized for high performance. The correct function of the NDIR detector is automatically checked on a regular basis by a zero point correction and sensitivity tests. This ensures that deviations are quickly detected and guarantees precise results.
