Balance, Weights, and Weighing SMK Negeri 13 Bandung
2
Teknologi dan Rekayasa Objectives After this session, the students are expected to be able : 1.To identify types of balance 2.To identify the component of analytical balance 3.To operating balance 4.To count weight

Teknologi dan Rekayasa Types of Balances Ainsworth; accurate single-pan balance, digital in line readout, substitution method of weighing, accuracy 0.0001 gram. Sartorious; accurate single-pan balance, digital in line readout, substitution method of weighing, accuracy 0.0001 gram. Single-pan; top-loading, substitution-type, rapid-reading balance with varied sensitivities, optical micrometer scale. Portable spring for coarse weighing object. Double-pan, analytical balance, manual weight and rider adjustment, readout to 0.0001 gram.

Teknologi dan Rekayasa Types of Balances Double-pan, chainomatic balance. Chain device adjusts weight addition to 0.0001 gram. Double-pan balance for general laboratory weighing, sensitivity 0.1 gram and used with counterbalance containers. Torsion, dial-reading balance. Rapid adjustment of the 10 gram weight increment by rotation of dial. Triple-beam balance with hooks for specific-gravity determination. Triple-beam balance for general laboratory weighing, sensitivity 0.1 gram for direct weighing, with all attached weights to increase capacity.
5
Teknologi dan Rekayasa Component of Analytical Balance Balance Scoop, used to weigh sample powder which are easily poured with the spout. Balance Weighing Dish, used weighing small quantities of liquids or solids. Balance Weights; Analytical balance weights with forceps from 1 mg to 100 grams. Handle with forceps because they are precision weights. One-piece brass weights, to be used where accuracy permits (weights from 1 gram to 2000 gram).
6
Teknologi dan Rekayasa Analytical Balance For analytical purposes a balance with a maximum load of 100-200 g and a sensitivity 0f 0.1 mg usually required.
