Designed to save time for operators,
the new Reference System available on
Mahr’s latest generation MarCal
digital calipers is one of several design
improvements.

Unlike older models, which require
the zero position to be re-set
whenever the caliper is switched on,
the MarCal reference system retains
the zero setting. This means it is ready
to measure whenever
it is turned on or the
jaws are moved. A
convenient Reference
Lock protects the
setting from
operator error, while the new
Reference System is inherently energy
efficient – providing up to 50%
longer battery life than previous
models.

Resolution of the MarCal 16 EWR
model (available in three versions
with maximum measuring ranges
from 150 to 300mm) is 0.01mm with
an error limit of 0.03mm (0.05mm
for the 300mm version).
