A pair of scales: An instrument for measuring mass in a force field by balancing forces. Balance; Check weigher measures precise weight of items in a conveyor line, rejecting underweight or overweight objects. Inertial balance; Katharometer; Mass spectrometers measure the mass-to-charge ratio, not the mass, of ionised particles. Weighing scale
This process will then need to be repeated for the 10 gram increments (20g) and then single figure units (7g). Riders - The riders are the sliding pointers placed on top of the balance beams to indicate the mass in grams on the pan and beam. Pointers - The scale pointer marks the equal point of the object's mass on the scale and mass on the beam
An analytical balance (or chemical balance) is a class of balance designed to measure small mass in the sub-milligram range. The measuring pan of an analytical balance (0.1 mg resolution or better) is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation ...
The balance (also balance scale, beam balance and laboratory balance) was the first mass measuring instrument invented. [1] In its traditional form, it consists of a pivoted horizontal lever with arms of equal length – the beam or tron – and a weighing pan [ 10 ] suspended from each arm (hence the plural name " scales " for a weighing ...
Instrumentation is a collective term for measuring instruments, used for indicating, measuring, and recording physical quantities. It is also a field of study about the art and science about making measurement instruments, involving the related areas of metrology , automation , and control theory .
used to separate particles dispersed in a liquid according to their molecular mass and aid in recognition Electrophoresis apparatus: used to detect and classify serum proteins or proteins from any other source. Also used for DNA separation. Chemical laboratory apparatus: for Chemical tests: Chromatography:
