Dear Sirs. Hello, my name is Klaus Illmer and I work as a technical inspector (and others services) for my company Detroit Chile S.A., I’m marine engineer.
Recently I bought (in a street market) an old instrument, it is a “TDS or conductivity analyzer” made by UNILOC model 770. One of my hobbies is to collect old instrument apparatus and to repair them; I have several ones, near 30; between others: noise reading, transsitors test, termomethers, planimeters, etc .
Off course there is no challenge if they don’t work correctly and, at the same time, if I can’t operate them accordingly wining in the process the knowledge of the instrument specific task and the utility of that information, in this case I learn a lot of umhos/cm (conductivity units), and TDS (total dissolved solids), etc.
There is no intentional commercial use of them.
The instrument was bought “as it is” and unfortunately without the operator’s manual and this is the reason to write to you, can you please scanner and send me a file of the manual?.
Thanks in advance.
Best regards.
KLAUS ILLMER
