The TG system can be used to check the thickness of rubber and rubber type
materials.
Note: The TG System is supplied with a 16mm diameter presser foot
and 212 gram mass. This configuration is commonly used for measurement of all
rubber materials with a hardness of 35 IRHD or below
Optional presser feet and mass combinations are available to check
a wide assortment of other material such as: foams, tapes, films, textiles, felts,
sheet metal, foils, fabrics, cloth, leather, fiberboard,
plywood, paper, etc.
1. Use the Adjustment Knob (1)
to position the Indicator so that the
the presser foot is resting freely on
granite base.
2. Clear indicator display to zero by
pressing and releasing the ON/ lr
key.
3. Use the Lifting Lever (2) mechanism
to raise the presser foot.
4. Place the material to be tested
under the Presser Foot (3) and
release the lifting lever.
Note: odel TG is supplied with a unique air-damping feature that controls the
rate of decent of the presser foot (not supplied with odel TG-DX). This allows
the presser foot to descend at the same rate for each test, thus eliminating human
error resulting in superior repeatability.
5. If required, the rate of descent can be user-adjusted by carefully
turning the knurled knob located at the top of the air dampener
(turn clockwise to slow the rate, counter-clockwise to speed up
the rate). Care should be taken to not over adjust the dampener
by over-rotating the adjustment knob.
6. Read and record the thickness of the material immediately after
the presser foot makes full contact with the material.
Note: The pressure being applied by the instrument has a significant effect on the
results obtained. The weight (mass) and presser foot diameter should be specified.
