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

The S-T Industries hand tools catalogue descibes most types of general inspection gauges and accessories used today in engineering inspection.

Some special products are not shown in the catalogue being only available on request.

Shown here is a long range 16" to 17" internal micrometer with fixing brackets for precise measurement location.

Many of our customers buy just the articulated arm assembly on its own, They are ideal for positioning and holding various items in exact positions.  Simply position the arm as required then aquick twist of the locking knob and the flexible arm becomes a firm and solid beam.

Shown above Fisso arms type 3300 and 2200 , fixing threads to hold base or part are 5mm and 8mm.

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..

Comtorgage have specialized in production bore measurement for over 70 years..

2 point, 3 point and blade bore gauges are shown below with mechanical, digital or transducers readout options. Gauges are customed designed to meet the accuracy required and measurement application.

We supply many  types gauging sensors, transducers, electronic probes and styli used in instruments and systems of various types.  Surface finish sensors, production  gauging probes in fixtures, machine tool control sensors etc.

Highly specialist products include Metrol CNC machine tool setting sensors.sensors and Kosaka surface finish pick-ups of all types.  

Photographs  show Kosaka PUC surface finish pick-up with interchangeable styli, a electronic probes and Metrol CNC sensor head.

Here's a fact not so well known in metrology of particular interest to quality and support engineers involved in volume production using gauging fixtures.

We offer a worldwide service to repair regular types of  electronic transducers and probes.When the probes on your gauging fixtures fail, d'ont just replace, save money by allowing us to repair and re-furbish them.  We fit replacement bearings, tips, lead connections etc and test them out before returning to our customers.  

An estimate is always given  prior to work being commenced but fully refurbushed probes cost approx. half as much as buying new.
