Before you choose

Does ECO 6 test for pesticides?

No. It provides indicative nitrate readings for supported fresh foods. It does not detect pesticides or heavy metals and does not replace laboratory analysis.

Does a low TDS result mean water is safe?

No. TDS measures total dissolved solids. It does not identify every contaminant or establish drinking-water safety.

Which languages are available on the device?

ECO 6 has two menu configurations: English/German/French/Spanish/Italian, or English/German/Bulgarian/Romanian/Russian. Printed instructions are in English and Bulgarian. Choose your required menu language on the product page before adding the device to your cart. For a language not listed, contact us before ordering.
