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. |
