质量检验设备无论其结构繁简如何，其最终输出均是以直接或间接的方式测出被测产品的质量技术参数的数值，即量值。它是判定产品质量是否符合特定规范要求的重要依据。测量得到的量值是否准确，乃是质检设备的首要条件。但是多年来，各地对质检设备的管理仍是一个较为薄弱的环 Regardless of its structure, quality inspection equipment, the final output is measured directly or indirectly measured the quality and technical parameters of the product value, that is, the value. It is an important basis for determining whether the product quality meets the requirements of specific specifications. The measured value is accurate, but the primary condition of quality inspection equipment. However, over the years, the management of quality control equipment in various places is still a weaker link
