Continuous TOC determination Using the UV persulphate method

QuickTOCuv is an online measuring system that determines the parameter TOC using the UV persuphate 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.

Accurate. Reliable. Trusted Measurement.

QuickTOCuv process controls have been optimized for high performance. 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 Validation. 

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.
