Replacement Standard pick-up (SR-112-1503)
Details as the standard pick-up, (see figure 6 pg 2.5) 10mm (400min) stylus tip radius.
Conforms to US specifications (ANSI B46.1).
Small bore pick-up, 5µm (200µin) stylus tip radius (SR-112-1504)
For general use in small bores, on narrow surfaces and in grooves, or with the skid supported
independently of the surface being measured. On this pick-up the skid is integral with the
stylus arm housing and is set further back from the stylus. This enables the pick-up to be used
in short bores with the skid supported independently of the surface being measured, eg by the
datum support stand.

Right Angle Pick-up, 5µm (200µin) stylus tip radius (SR-112-1505)
This pick-up is used at right angles to the direction of traverse. Accordingly the skid is set at
right angles to its normal position.
It is particular useful in grooves or slots where the lay of the surface texture makes it unsuitable
for measurement with a standard or small bore pick-up. When used on cylindrical workpieces
it is important that the stylus and skid should be equidistant from the crest (see figure 11), and
that the work piece is positioned so that the crest is parallel to the line of traverse.
