The Bowers XT500 large diameter 3-point bore-gauge has been designed specifically for the measurement of internal diameters between 300 and 500mm. The constant-force digital readout ensures that the measuring pressure remains constant throughout the measurement whilst radiused measuring anvils provide optimum centralisation in the part.

Anvil sets are supplied in 25mm steps (300-325, 325-350 etc) and each set has been manufactured to the exact tolerance size. The 300-325mm anvils are the master reference set and are used for setting the gauge in the setting ring. The other anvil sets are then fitted as required without further re-setting. This means that only one 300mm setting ring is required to set the gauge for all diameters in the full 300-500mm range of the instrument.
