To satisfy increasing customer demand we have, over the years, expanded our range of quality instruments into many areas of shop-floor measurement and now also offer cost effective, quality solutions to external, depth and height measurement problems. Having translated the Bowers ethos of accuracy, quality, ease of use and value for money into our now extremely comprehensive range of gauges, we are currently the supplier of choice for hand held measuring instruments to many engineering and manufacturing companies throughout the world.

Bowers Mechanical Cylinder Bore Gauges have been further improved giving even greater ease of use and reliability. The introduction of tungsten carbide contact points ensures superior wear resistance. Suitable for use in most environments, these gauges are particularly useful for detecting ovality, or taking measurements relatively deep inside bores.
