Guest n0r1s Posted May 21, 2007 Share Posted May 21, 2007 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. http://www.octiva.net/projects/ppm/ date tehnice: http://www.coleparmer.com/techinfo/tech ... tivity.htm http://www.lenntech.com/unit-conversion ... engels.htm 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.
