ACCESSORIES MICROTEST-AG
I- Elbow and Extensions


– For MICROTEST® Internal Micrometers tillØ 400 mm we offer our clients elbows and extensions.
– We can combine extensions up to 10 meters or more. Since the length measurement remains on the axis of the work piece, temperature has no effect on the extension or display.
– The Available extension lengths are: 50, 100, 200, 350, 500, 750, 1000 and 1500 mm measurement remains as accurate as in a standard unit.



– The MICROTEST®-Tripod supports the internal micrometer with extension to achieve an optimal pre-centring of the whole unit in the deep bore hole. The measurement unit can be introduced on rubber rollers, without scratching the bore. From 1,5 meter extensions onward it is recommended to use our MICROTEST®-Tripod, similar to Bessel‘s rule. In the case of very long applications further tripods should be fitted for support.To guide the MICROTEST®-Tripod viaradial recesses, we supply appropriate cables for this purpose.
– Dimensions Equipment:
Ø60 – 90 mm
Ø90 – 140 mm
Ø140 – 240 mm
Ø240 – 400 mm
II- Calibration Rings and Gauges


– Our MICROTEST® calibration standard is in accordance with DIN 2250 or better.. We provide you with high-precision, lapped calibration rings for the most demanding applications.
– An other option is our universal calibration gauge for all Microtest devices from Ø 30 mm – Ø 400 mm with hardchromed measuring faces.
– On request different sizes are available!

III- Custom-Made: Special Instruments :


– Based on our normal construction we design and manufacture instruments to our customers needs!
– MICROTEST® special micrometers such as ball track micrometers or radial recess micrometers, as well as the 3-point external measuring unit, are unique and unrivalled
– e.g. for turbocharger labyrinth or similar special tasks.For further information don’t hesitate to call us!
