BOWARROW 330
DESCRIPTION
Bowarrow 330 (13″) caliper calculates the wheel diameter by measuring the versine of the wheel arc encompassed between two tungsten carbide spherical points. A digital comparator performs a precise calculation of diameter.
FEATURES
. Range: Wheel diameter from 600 mm (23,6”) to 1400 mm (55,1”).
. Resolution: 0,1mm
. Accuracy: +-0,3mm (use of wheel block diameter enhances accuracy up to +-0,2mm)
. Roundness: you can evaluate the wheel roundness. The gauge has two tungsten carbide spherical balls that can slide easily over the tread.
. Measuring units: in/mm
. Weight: 1,7Kg
Reference wheel bloks diameters: ØA and ØB. (Wheel diameters more often measured).
These arcs are used to PRESET quickly your Bowarrow to a known diameter. This way allows you to enhance the gauge accuracy.
