The Fowler-Bowers 54-551-010 MicroGage Set: 2-point bore gage set was introduced to the Fowler product line in 2012 and gives end users a very accurate and repeatable way of measure small diameter bores. Fowler is currently stocking some of the larger sets of the MicroGage but individual ranges, depth stops, and stands are available upon request.  The MicroGage is a great solution for customer trying to measure small bore under .250″/6mm. .Bowers Metrology is the manufacturer of the MicroGage bore gage but these gages are sold through Fowler High Precision in the USA.

The new Fowler-Bowers MicroGage 2-point bore gaging system has been designed specifically for the measurement of small bores between 1.0 – 6.0mm. Featuring a completely new digital readout and extremely compact overall dimensions, the MicroGage is truly a pocket-sized instrument. Digital readout and measuring head together are about the same size and format as a ballpoint pen which represents a big advantage for those needing to measure small precision parts and who needs to have their gage with them all the time. The clear LCD display is easily set using only two buttons and results are shown with switchable 0.01/0.001/0.0005mm resolution. Data transfer is via Proximity-RS232 or Proximity-USB output. The measuring heads are equipped with spherical hard-chromed contact points and are set in appropriate setting rings. Like all Bowers bore gaging products the MicroGage

 system is available as individual instruments or as full sets. All setting rings are supplied as standard with UKAS certification.
