Special manually operated instruments with an electronic digital readout:
Model 4153

The model 4153 inside gauge is intended to be used for measuring the diameter of an opening in the hub of railway wheels.

With its aid a quick and accurate measurement of the opening in the hub of a railway wheel is carried out when such an opening is being made on a machine-tool.

The results of measurements are shown on the visual display of the built-in electronic digital indicator MILLITAST 1082 of the German company Mahr.
The setting-up of the instrument is carried out with the aid of a reference gauge (included in the complete set) by a single depression of a push button on the front panel of the electronic unit.

The utilization of the inside gauge is especially effective when it is used in combination with the wide measuring range ROBOCON snap gauge model 4154 for measuring the hub contacting surfaces of vans’ axles.

The instrument has been certified The Russian Federation State Standard Certificate No. 18722-99 . Registration Certificate No. МТ 059.99 in the Branch of Industry Register of measuring means permitted to be used within the railway transport.
