Dear Sir, I need some clarity for this item. I want to measure TDS of 0.1 ml solution. Can you provide what is the minimum solution required for measuring the TDS of solution and lower limit of TDS. One more think I want to know about thos item , how long it will take for response. Because in flow system 25 ml/min in pipeline I want to measure the conductivity change for 1 min continously. In I min how many data point I can get. This is my aim. I will wait for your response. Thanks and Regards Rabiul Show More
