Replica Kit (112/727)
Surfaces inaccessible to the Surtronic pick-up can be measured
indirectly if a replica of the surface is made. The replica kit
provides prepared quantities of materials for making a replica.
On surfaces having an Ra of less than 0.2um (8uin), the Ra of the
replica is likely to be higher than that of the original surface, while
for surfaces having an Ra greater than 4um (160uin) the roughness
of the replica is likely to be lower.
Detailed instructions are included with the kit, but briefly the
procedure is as follows. An area not exceeding 400mm² is
enclosed by a thin wall of the 'plasticine' provided. The solution is
then poured onto the area and allowed to harden, which takes
about 12-15 minutes. The replica is then removed from the
surface and measured with the Surtronic in the usual way. No
difficulty is experienced in removing the replica from the surface
as this is facilitated by the application of the release agent.
Note: because the surface has been obtained by a replica, the
profile will be inverted, however this will not affect the Ra value.
Portable base (137/1734)
The Surtronic 25 can be mounted on a portable base for use in
measuring large components in situ. The base is fitted with 3 feet
which can be positioned at a number of places on the base,
enabling it to be steadied on a variety of components.
