effect of electrostatic at surface tension measurement using Wilhelmy plate method
2019-2-19 10:42:17

USA KINO (http://www.usakino.com) adopts ionic wind technology to avoid detection error of liquid-gas interface caused by electrostatic. When there 's electrostatic existing, liquid interface will rise, sensing interface (plate or ring) will contact with it ahead of time, hence measurement value of surface tension using Wilhelmy plate method will be larger than normal , measured value is 71.214mN/m with electrostatic and 70.891 mN/m when used antistatic kit.
