For sale is my mastertronic automatic water test form focustronic
very hard to find, I pre-ordered and was one of the first people in the United States to receive a unit at the start of this year
asking $750 (Retail is over $1k)
Unfortunately, my plans have changed and I haven't even used it.
It measures PO4/ NO3/ Ca / Mg / dKH* / OLI
Cell is 347-602-2017
