 |  |  |  | Dial Inside Micrometers NI series
Inside 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.
