I do not doubt that the Elos kits are accurate, but the
Ca and
Alk kits have very low resolution compared to Salifert. (Each drop in the
Alk kit is 1 dKH, each drop in the Elos
Ca kit is 25ppm!) Please see my informal
Alk comparison. You can increase the Elos resolution by using twice the amount of
SW, but you would have to triple the amount of
SW to approximate the much smaller drop size of the respective Salifert kits (all due to those precision Salifert syringe tips). You would burn through a lot of Elos reagent, and those kits aren't cheap.
In the end, the Elos
Ca & KH kits are nice (probably fine for casual use), but - low resolution obscures its accuracy. I emailed the Elos rep (Jesse Sira - fantastic guy), who said that Elos was going to address this issue with a few kits shortly (around Interzoo).
IMHO, Elos simply needs more precise droppers in these kits.
