Analytical scales are usually used to weigh objects that require high accuracy calculations such as chemicals in the laboratory or drug ingredients in pharmaceutical laboratories. Analytical scales are able to read units of weight to very small because analytical scales use laser sensors as sensors of the weight of the scales. Numbers that can be read by this scale are up to four digits behind the comma in units (units) gram which is 0.0001 g or 0.1 mg.
Digital scales are equipped with digital systems, so there is no doubt in the level of accuracy and precision in the calculation. Usually there is also an additional feature in the form of a glass protector that aims so that the wind does not interfere with the research process, so that in a free-of-vibration weighing due to wind blowing can cause vibration.
