TOC system |
Range : 0 to 200 ppb Resolution : 1ppb, Reproducibilty : +/- 5% , Accuracy : +/- 10% Temperature : 5 to 35¡É Composition : Conductivity sensor for TOC...S1, S2 .....................Temp sensor for TOC...T1, T2 .....................184.9mm UV lamp for TOC .....................UV chamber .....................Volumetric valve Error display : 9 message (UV lamp, Temp sensor, TOC value, Over range,etc) Principle : CO2 is generated by oxidation of the organics in UP water with 184.9nm UV light. It affects the conductivity value (compensated at 25¡É) and TOC value can be messured from this change. |
