Diatest 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 diameters.

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 attachment.

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 versatile.
