量具按其用处可分为三大类：
１、标准量具。指用作测量或检定标准的量具。如量块、划线平板、多面棱体、外观粗拙度相比样块等；
２、通用量具（或称万能量具）。１般指由量具厂统１制造的通用性量具。如直尺、平板、角度块、卡尺等；
三、专用量具（或称非标量具）。指顺带为检测工件某１技能参数而经牵制造的量具。如表里沟槽卡尺、钢丝绳卡尺、步距规等量具因而固定形式复现量值的测量用具。
它的赋性以下：
１、本身直接复现了单位量值，即量具的标称值便是单位量值的理论大小，如量块本身就复现了长度量的单位；
２、在布局上１般没有测量机构，没有指示器或流动着的元部件。如量块只是复现单位量值的１个实物；
三、由于没有测量机构，如不寄予别的配用的测量用具，就不克不及直接测出被测量值。譬喻量块要配用干涉仪、光学计。因而它是１种积极式测量用具。

According to the measuring tool use can be divided into three categories:
1, standard measuring tool. Refers to the standard used as measurement or verification measuring tool. If LiangKuai, crossed plate, many faces, edges body appearance CuZhuo degrees sample blocks, etc; compared
2, general measure (or said that universal measuring tools). 1 a show by the measuring tool factory all 1 manufacturing of general measuring tool. If a ruler, plate, block, caliper, etc; Angle
Three, special measure (or says non-standard measuring tools). Refers to a 1 for testing by the parameters and the skills and manufacturing measuring tool. Such as list, wire rope caliper, groove caliper step distance measuring tools and fixed form such as customs reiteration of the value of measurement appliance.
It's natural the following:
1, itself directly resembles the unit, that is the value of the nominal value is measuring unit of the value of theory, such as the size LiangKuai itself resembles the long measure of unit;
2, 1 on layout as no measurement institutions, no indicator or flow of yuan components. If LiangKuai just retrieval unit of the value of a real;
Three, because no measurement institutions, such as not send the measuring appliance with other, means less than the direct measurement was measured values. The interpretation LiangKuai to with interferometer, optical plan. So it is a positive type measuring appliance.
