Dial Inside Micrometers NI seriesInside dial gauges are intended tor measuring of internal sizes. In models NI-10 and NI-18 inside dial gauges the value ot travel ot the movable measuring rod is imparted to the reading device through a V-belt drive,while in models NI-50M - NI-450M inside dial gauges, by lever-type drive. In NI-700 and NI-1000 inside dial gauges the movable measuring rod directly contacts the reading device. To match the moasuring line with the axial plane ot the hole being measured the inside dial gauges are provided with centering bridge (in NI-10 inside dial gauge a centering bridge is not available). The gauge is set for the required size with the help of changeable measuring rods (washers, extension rods) according to certified rings or to block gauges with sides.
