We have 2 of the 100 modular digital model on cheorae. 24 v dc
Worked well. They use a standard membrane that I bought from forum
member Tellie., and I ordered 2 sets of replacement o rings directly from schenker wich shipped promptly.
Made around the rated amount with tds around 220- 250 with a new membrane.
My only issue is the digital display is in italian and I havent figur d out how to change it to
english. I have the manual in
English, but the
rebuild instruction I could only get in italian.
Regards
Paul
