Internal Bore Measurement

Product Details

Diatest produces a wide range of simple to use
instruments for internal bore measurement

From prototyping to large production requirements, Diatest offers
a wide variety of instruments to test and measure internal bore

Plug gauges are perfect for testing of production pieces as they
offer very fast and accurate results with minimal user error.
With a 2 point design Diatest BMDPlug Gauges are able to
accurately repeat measurements of down to 0.001mm

Plunger probes are great for the workshop or testing of different
pieces as they can measure a wide range of sizes with the right

Diatest measuring plugs and gauges can also be used with other
brands of indicators allowing you to add more accurate and
precise instruments to your shop with minimal investment.

Diatron also offers electronic and wireless data transmission and
recording with it’s Diatron and Diawireless offerings expanding
their range of bore measurement technologies to be even more
