Dresser engineers have devel-oped a new generation of test gauges to meet the exacting needs of instrument engineers and quality specialists. The new Ashcroft ? MicroSpan > Ι adjustment for ease inspan calibration. This device per- mits precise adjustments to achieve exact span calibration from 0 to 100% of scale. The microme- ter screw attached to the slide will vary the span by approximately ? Hydraulically staked movement pro-vides improved stability. The movement, with Teflon > coatedgears and bearings, uses a unique hydraulic staking operation to ensure a rigid movement frame that resists...
