XT Analogue Three Point Bore Gauge

XT ANALOGUE THREE POINT MECHANICAL BORE GAUGE

Bowers XT Analogue three Point Mechanical Bore Gauges are an economical solution to accurate shop-floor bore measurement.

The extended mechanical travel of these advanced two or three point gauges ensures that exchanging measuring anvils is now unnecessary.

Their wide application range, 2-300mm, rugged construction and easy read scale, ensure both accuracy and ease of use. XT measuring heads and setting rings are supplied with UKAS certification. Bowers has developed XTA Micro to cover the measuring range 2-20mm. The XTA Micro incorporates a more compact mechanical controller and Vernier scale for improved resolution.
