salut

am avut nevoie de niste informatii legate de masurarea puritatii apei si am dat peste proiectul unui aparat pt masurarea conductivitatii lichidelor.

nu l-am construit insa poate intereseaza pe cineva.

date tehnice:

catalogarea apei dupa uS:

apa pura 0.055 uS/cm

apa oras 50 uS/cm

 

in Bucuresti avem ~180PPM si 338uS la 24C. o apa filtrata prin osmoza inversa la 3.5bari are 14PPM si 34uS la 23C. apa distilata de se cumpara la benzinarii are 0.2-0.9PPM.

 

daca se apuca cineva sa-l construiasca as fi curios la cit se ridica pretul.
