Hello to All,


May I please request any help regarding finding and SOP or operation manual for an amperometric titrator made by Siemens, A-790?


I found a new unit in our warehouse, but there was no literature from the manufacturer inside the box. We will use it for chlorine and SO2 residuals. 


Thank you very much!


Manuel S.

Have you tried contacting your local Siemens representative? My experience with most Siemens product lines is that most needed information is available on line, but it is almost impossible to find without guidance.

Just Google Wallace and Tiernan A790 and there should be a manual. The W & T is now Siemens.
