1.0Introduction:
BGD151 RotaryViscometerisused inmeasuringviscosityfriction and absoluteviscosityofliquid.It
hasfourrotorsofNO.1-4and can bechosentouseinaccordwithviscosityofthe liquidtobedetermined
rotation speed.It iswidelyused todetermined viscosityofvariousliquidsuchasoil,paint, plastic,food
medicine, adhesive, etc. It iswidelyapplied inthe fieldofpetrochemistry, medicine, food, light industry,
textileindustry,scientificresearch, etc.
