TOC Analyzer QuickTOCuv II

TOC Analyzer for Clean and Pure Water

Our new and improved QuickTOCuv II

In 2021, we have improved and further developed our proven Total Organic Carbon (TOC) analyzer with UV persulfate oxidation – our QuickTOCuv.

Our new 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. The measurement system is controlled by a user-friendly 4″ PLC with touch screen.

LAR’s TOC analyzer QuickTOCuv II is ideal for fast and reliable online monitoring in pure, drinking, surface and wastewater.

Continuous TOC determination.
Using the UV persulfate method.

QuickTOCuv is an online measuring system that determines the parameter TOC using the UV persulfate method. In addition, different versions of the measuring device can be supplied and it can thus also be used in Ex zones. TOC determination is carried out in accordance with the standards DIN EN 1484:1997 and US-EPA 415.2.

The measuring technology. Reliable.

The QuickTOCuv process controls have been optimised in all areas. Additional sensors and carrier gas preparation are optional. Reliable operation is guaranteed by the separation of the analytical compartment from the electronics and by the use of high-quality materials.

System checks. Automatic.

QuickTOCuv automatically carries out regular checks to assess correct function of NDIR detector by zero point correction and sensitivity tests. This ensures that any deviations are rapidly detected and guarantees precise results.
