Model 512D Digital ASTM Type D Durometer
for plastics, hard rubber, epoxies, etc.
The ultimate durometer for accurate hand held
hardness measurements. PTC® leads you into
the new millennium with this durometer’s rened
styling. The durometer is easy to grip and the
1.25” diameter base has a large landing area for
increased stability and maximum repeatability.
The instrument uses a digital readout indicator
with bold, easy to read numbers. The unit has
an RS232 data port for downloading information
to a PC or printer. Features also include an auto
shutoff timer and low battery warning display.
These durometers meet or exceed all aspects
of ASTM D2240.
All durometers come complete with certication
traceable to NIST, test block, batteries, 115V
AC adaptor, and carrying case. The test blocks
are color coded to match the durometer type.
The blocks will read within ±1 point of a properly
functioning durometer.
PTC Me trology® is accred ite d by A2LA for
durometer calibration to ISO/IEC 17025 & ANSI/
NCSL Z540-1. NIST traceable certification is
available for all durometer types covered by current
ASTM D2240, ASTM F1957, ISO 868, ISO 7619,
and DIN 53505 Standards.
The Calibration Report will include both "as
received" and "as left" data. Complete durometer
ca lib rat ion i ncl udes: ind ent er ge ome try a nd
extension, indicator linearity, and force curve.
Other durometer types, custom models, and
durometers of any manufacture can also be certied
by PTC Metrology®.

GENERAL OPERATING INSTRUCTIONS
The following procedures are based on ASTM
Standard D2240. This standard is recognized as
being denitive, however, not all applications require
such stringent controls.
Readings below 10/A may be inexact and should not
be reported. Readings above 90/A may be inexact and
should be made on a Type D durometer. Readings
below 10/D should be made on a Type A durometer.
The surface of the sample to be tested shall be
clean and smooth. The sample should be at least 1/4"
(6 mm) in thickness unless it is known that identical
results are obtained with a thinner specimen. Thinner
materials can be stacked to obtain the minimum
thickness (DO NOT GLUE). Such results may not
agree with those of a solid specimen. Most materials
above 50/D can be tested with a 1/8" (3 mm) minimum
thickness. The sample should be large enough so
that the indenter is at least 1/2" (12 mm) from any
edge unless it is known that identical results are
obtained when measurements are made closer to the
edge. The surface of the specimen shall be at over
a sufcient area to permit the presser foot to contact
the specimen over an area having a radius of at least
1/4" from the indenter point. The temperature of the
specimen should be 73.4°F ±3.5°F (23°C ±2°C). The
specimen should be allowed to rest at this temperature
for at least 1 hour prior to testing, as the properties of
most materials change with temperature.
Place the specimen on a hard, horizontal surface.
With the durometer held vertically, press and hold
release the 'ON/clr' button to turn on the digital
indicator. If desired, press and release the 'HOLD'
buton to enable max-hold. Hold the durometer
vertically with the point of the indenter at least 1/2 "
from any edge. Apply the presser foot to the specimen
as rapidly as possible, without shock, keeping the
foot parallel to the surface of the specimen. Apply
just sufcient force to obtain rm contact between
the presser foot and the specimen. Hold for 1 or 2
seconds, the maximum reading can be obtained by a
setting on the indicator (see above). When max-hold is
enabled the maximum value reached will automatically
be displaced and held until reset. To disengage the
maximum feature, press and release 'HOLD' button
again. If other than a maximum reading is needed,
hold the durometer in place without motion and obtain
the reading after the required time interval. Make 5
tests at least 1/4" apart and use the average value.
LIMITED LIABILITY WARRANTY
PTC® products are covered by a limited liability
warranty from defects in material and workmanship for
one year from date of purchase. This warranty does not
apply if, in the judgement of PTC®, the product fails due
to damage from shipment, handling, storage, accident,
abuse or misuse, or if it has been used or maintained in
a manner not conforming to product's instructions, has
been modied in any way, or has a defaced or removed
serial number. Repair by anyone other than PTC® or
an approved agent voids this warranty. The maximum
liability of PTC® is the product purchase price.
Power On
Press and hold ON/CLR until indicator turns on.
Power Off
Press OFF/MODE
Auto-Off Toggle
Press the 2ND button until 2ND appears on the display.
Press the OFF/MODE.
An hour glass appears at left side of display if AUTO OFF
is active. If AUTO OFF is active the indicator will power
off in 10 minutes with no activity (button press or spindle
movement).
Hold Mode
Allows you to hold the value on the display according to
the specied mode.
Press HOLD to toggle hold mode on and off.
MAX - Holds and displays the highest reading attained.
MIN - Holds and displays the lowest reading attained.
FRZ - Holds and displays the reading displayed when HOLD
is engaged.
Note: Pressing ON/CLR button resets indicator to spindle
position except in FRZ; resets to zero.
Reset to Factory Default
This will set all features and functions back to the factory
default settings.
Press the 2ND button (2ND icon should appear on the
display), followed by ON/CLR, then press IN/MM.
Note: Factory defaults cannot be reset if the LOCK feature
is on.
CALIBRATION CHECK
For a complete calibration check of mainspring, and visual
and mechanical check of indenter, the instrument should be
returned to PTC® (see Guarantee & Calibration Service) or
refer to ASTM D2240 Specications. PTC® recommends
the unit be returned at least every 12 months for this check.
For a quick eld check, follow the guideline below. Under no
circumstance should a test block be used as a standard to
calibrate a durometer.
1. The pointer should read zero when no force is applied to
the indenter of the durometer.
2. Hand hold the durometer and insert the indenter into the
hole of the calibrated test block. Apply enough force to make
rm contact between the top surface of the test block and the
presser foot. The dial reading should agree with the value
stamped on the check block (±1). Several tests should be
made and the results averaged.
3. The indenter must protrude 0.098 to 0.100 inches below
the presser foot.
4. When the indenter is fully displaced, the durometer
should read 100 points. Use care as to not damage the tip of
the indenter.
