No, but I worked for Metrohm for many years.
I think the communications protocol is, opposed to the titrinos, not public.
The titrando is aimed at certified laboratories, controllable only by software which is CFR compliant and all that.
May not neccessarily be correct, but that's my memory of the situation (I left Metrohm a few years back).
