After producing redox probes for about 20 years, I have decided to move on and stop producing redox probes.
Of course I want to thank all of you who bought and used the probes. To continue after-sales support, part of my website (see menu) will remain online. And of course you can still contact me via firstname.lastname@example.org for repairs and/or additional questions.
If you are looking into buying new redox probes, I warmly recommend the SDI-12 probes produced by SWAP Instruments. With integrated reference electrode and redox measuring electronics they offer a further developed version of the fiberglass rod probes.
