The NEW model 49-85 Digital Micrometer combines a precision
thickness measuring system with an ultra-clear, easy-to-read digital
display. The motor-driven instrument utilizes the dead weight
micrometer principle for high accuracy and repeatability. Each unit
is designed and manufactured for use where the utmost precision is
required.
The model 49-85’s construction consists of a heavy, solid frame
which supports the unit and houses the reflective linear encoder and
associated circuitry. A digital readout is provided to automatically
display the specimen thickness. The lower anvil and movable pressure
foot is made from lapped, stainless steel.
Designed specifically with the paper industry in mind, the model 49-85
is configured to meet the international specification and test standard
for paper and board, TAPPI T 411.

GRAPHMASTER™ OPTION
GraphMaster™ provides data collection, plotting and
analysis with export capabilities for our 49-85/87 series of
Digital Micrometers. GraphMaster™ can profile a series of
measurements creating a real time plot of thickness versus
interval, or distance.
Sample trend and profiling analysis is easily done with
user definable target, minimum and maximum values.
GraphMaster™ provides a one click Database feature to save
critical test information and provide export reporting for
Microsoft® Windows® compatible programs.
