SUBITO

Precision bore gauge SUBITO V the original. Its construction principle has proven its worth a hundred thousand times. Its quality and liability still convince the technical world nowadays. The segment V also called<>- is the essential part of all SUBITO instruments. It ensures an absolutely repeatable transmission of the course of the contact pin via the connecting rod, to the indicator without backlash and with minimal friction. Many variants are available, which enable us to offer the right instrument for each application.

Plug gauge

The plug gauge OD is a robust and easy to use comparator measuring instrument, which is conceived for series control of bores. The OD plug gauge meets the following requirements:

Easy handling
Quick measurement
Maximal measurement certainty
Robustness and reliability

In the application range from diameter 2,5 to 500 mm, not only the diameter of each bore, but also its possible deviations in form, can be precisely measured. The deviation principle, with the wedge needle made of tungsten carbide, ensures a wear resisting function for many measurements. Different variants offer an individual solution to each measuring task.

OSIMESS

The OSIMESS internal measuring instrument is a mechanical two-point comparison measuring instrument for the diameter range from 1 to 40 mm. In addition to the diameter, also deviations in form, like roundness and conical form, can be measured.
The instrument holder can be readapted to the application needed, quickly and without additional tool, by means of the different exchangeable probes and corresponding measuring needles. The measuring needle is wedge-shaped, which automatically prevents it from twisting. It splits the measuring probe so open that the measuring surfaces are lying close to the wall of the bore. Measuring needle and probe are exactly coordinated geometrically, so that a maximal linearity and repeatability is ensured.

Measuring tapes

Circumference tapes of the series Circometer have been manufactured by the company OSKAR SCHWENK for more than 50 years. The circumference tapes are used for the measurement of outside circumferences of round parts. At the same time, the diameter or the circumference up to O 7500 mm can be measured. The smallest possible diameter is 10 mm.
Precision indicators and dial gauges

In order to complete our bore measuring instruments, a suitable display is necessary.
For this purpose, we offer the precision indicators Mytast and Centitast, as well as mechanical and digital dial gauges, which suit most applications.
