Harald Weigand

Hi Matthew, I'm afraid none would work. The probes themselves need to be made of Pt. (I hope I got you right)

I have successfully used the ecotech system (ecotech-bonn.de) in combination with a high-resistance data logger. They also work fine in log-term monitoring. Harald

Michel Vorenhout

See a publication by us on good working probes, or search the old publications by Michael J. Vepraskas. Harald is very right: brazing rods should never be used, and soldering Pt to Copper is prone for errors. In general it is much more efficient to buy them than to try by yourself.
