When  measurement of splines on shafts is required the Comtorgage hand held spline gauge is an ideal solution without compromising accuracy,  indeed these gauges excel over most other available solutions.   The Gauge itself comprises a substantial gauging anvil fitted with precison floating rollers, a mechanical or digital amplier and a setting  master. The self seating aspect of the gauge makes it easy to operate and ensures  high R&R results.

The picture above shows the gauge fitted with the 'world renown' Comtor mechanical amplifier

When it comes to requiring a larger than normal gauge stand Fisso has the answer with its famous articulated arm actions. 

The FISSO Series 5000 stand already has a massive capacity but when mounted on a column extension and fitted with large double magnets it has a secure reach of up to 1000mm / 40inch.

S-T Industries catalogue comprehensively covers the range of hand gauges and tools used in general the engineering and allied industries. The small bore diameter gauge shown below may be supplied to measure bores down to 100/150mm  in dia. ranges.: 10 to 18 /18  to 35/35 to 60/50 to 100/ 50 to150mm with imperial equivalents.

Shown here is a small bore comparator which, using a range of small add-on anvil tips measures between 10 and 18mm diameters. measures bores

When you require accurate external thread or spline measurement special Comtorgage gauges are your best option. Easy to use  without compromising accuracy, these specially designed and highly rugged snap gauges incorporate floating pins inside the measuring anvils and have mechanical dial or digital readout options.

Close up shows 3 floating parallel pins in snap, lower jaw closes and seats onto the thread or spline to be measured.

Many features like external and internal grooves and races have to be measured very accurately so blade gauge technology developed by Comtorgage has been designed to do just that.  The following are a few examples of blade applications.

Pictures show a deep groove gauge with double retration, and ring gauge with internal blades to measure a precisie bearing race and a single blade gauge for on machine shaft diameters measurement..
