USER MANUAL 47____________________________________________________________________________________________________________________16.12 Density measurementThis function allows for determination of solid body density, upon the basis of weight in the air and weightof material immersed in liquid of known density, according to the formula:m1ρ = * ρ liquidm1- m2where:m1-weight in airm2-weight in liquidThe measurement consists of two phases:Phase I – solid body sample measurement in the airPhase II – measurement with immersion in the liquidThis function also allows for determination of liquid density, upon the basis of plunger weight (with knowndensity) in the air and tested liquid. The following formula is used:m1 - m2ρ = Vwhere:m1-plunger mass in the airm2-plunger mass in the liquidV – plunger volumeThe plunger volume is indicated on its hanger.This measurement also takes place in two phases:Phase I – plunger measurement in the airPhase II – measurement with immersion in the liquidMore comprehensive description is delivered with the Hydro Set.
