Balances for Special Applications

Some special applications and the corresponding balances are described in detail: laboratory balances, micro balances vacuum balances, thermo balances, magnetic suspension balances, oscillators, metrological comparators, tensiometer, suspended particles and elementary charge, mass analyser, density determination, particle analysis, magnetic susceptibility, post office and coin scales, body scales, and gravimeter. Vacuum equipment for balances, thermogravimetry, sorptometry, hygrometry, and moisture determination, gravimetric measurement of reaction kinetics, surface tension, ion traps, pyknometry, dust and particle concentration, grain size analysis are described. Gravimetric measurement of gas pressure and temperature are reported. The use of safety valves is explained. The application of weighing for medical purposes is discussed. Mass determination in astronomy is described. Some weighing curiosities are reported.
