美国新泽西州的MTI 公司提供一种468系列手动内径量规,其特点是,除了游标尺之外,还有液晶数码显示器。由于量规具有统计过程控制(SPC)功能,并可快速打印出控制图表,分析管理数据和直方图,所以可将内径测量数据直接输入公司的微管理机和接口。如不用SPC 功能,该量仪仍可作为手动内径量规使用。其它特点还有:装有棘轮停止器,保证控制和测量的一致性;耐用的硬质合金测头;用于测量特殊预定直径的定位指示器预置按钮;用于零点定位的复位显示器绝对零
MTI Corporation of New Jersey, USA, offers a 468 Series Manual Internal Diameter Gauge that features a liquid crystal digital display in addition to the dipstick. Because gauges have statistical process control (SPC) capabilities and quickly print out control charts, analysis management data, and histograms, it is possible to enter ID measurements directly into the company’s micromanagers and interfaces. Without SPC function, the gauge can still be used as a manual gauge. Other features include: Equipped with a ratchet stop, to ensure consistency of control and measurement; durable carbide probe; used to measure the specific pre-set diameter positioning indicator preset button; reset display for zero positioning absolute zero
