Abstract:
     The invention discloses a small-article bulk and density measuring method and device through electronic balance, which is characterized by the following: measuring the small-article quality W object and full-immersed drained liquid quality W in the density-known liquid through high precise electronic balance; adapting the formula: W＝F/g, F＝ρ liquid gv drain to calculate the bulk of small-article, wherein the v drain= v object= W/ρ liquid; ρ object = ρ liquid W object/ W; the device contains electronic balance with weight carrier, thread on the carrier and carrier holder under the thread. The invention is easy and convenient to operate, which improves the measuring precision.
