Thank you very much for your inquiry regarding OPTEX water Analyzer.
TC-3000 and TS-MxS-A are on line sensors to monitor the trend of water Turbidity or Suspended Solids. In other words, the values by the sensors are not the absolute values. For example, DIN 38414 is the determination of the official method to measure the sludge of water. That standard provides that the manual analysis must be only the official method. Therefore, if you need to get the absolute value, that manual analysis must be only the way to do that. In that case, you can not get the continuous data from them because it is just manual analysis.
The online sensors are used to get the trend of water quality. The manual analysis is used to get the absolute values. The purpose is different from each other.
