DIGITAL MICROMETERS
49-85,86,87 SERIES
INTRODUCTION
The TMI Digital Micrometer 49-8X Series measures the thickness of sheet material in the following
ranges:
Depending on the Model
49-85 and 49-86
0-0.050 in (Imperial Units)
0-1.27 mm (SI Units)
49-87
0-0.500 in (Imperial Units)
0-12.7 mm (SI Units)
The TMI Digital Micrometers
–
49-8X Series combines a precision thickness measuring system with a
digital readout. The motor-driven instrument utilizes the dead weight micrometer principle. Each unit
has been designed and manufactured for use where the utmost precision is required, completely free of
operator influence.
The instrument consists of a heavy, solid frame which supports the unit and houses the thickness
measurement transducer and associated circuitry. A digital readout is provided to automatically
display the actual specimen thickness. The lower anvil as well as a movable pressure foot is made from
lapped, stainless steel.
APPLICATION
The TMI Micrometer is designed to measure the thickness or caliper of paper sheets, films and foils.
Almost any material including paper, natural or synthetic fabrics, leathers, metals, plastics and rubber
thickness can be measured with precision and accuracy. The 49-86 and 49-87 models also feature an
on board statistics package that stores up to 100 readings, calculates and displays the average, standard
deviation, maximum and minimum of the readings that are stored in the instrument’s temporary
memory.
