One grandfather came here at work, a grit nitrate sensor bought! (I see two electrodes turning)

d - here is the water from under the crane fucking, in the refrigerator is better, but distilled, specially bought to compare, generally zero shows!

I - go here with the distillate, and throw a spoonful of salt there. How many nitrates have I added? (There it was up there)

Grandpa was offended.
