Universal and Portable
Penetrometers
Introduction
Universal Penetrometer— H-1200
Direct-reading instrument for precision penetration measurements of bituminous
materials, cement, petrolatum and waxes, as well as food, cosmetics and pharmaceutical
products. Unit has 5" diameter indicator dial, graduated in 400 divisions of 0.1mm,
corresponding to 40mm penetration. Zero preset to eliminate errors. Includes 47.5g
plunger with 3.2mm hole, and two loading weights (50g and 100g). Overall dim. 10-1/2"
x 13" x 22" (266.7 x 330.2 x 558.8mm). Meets ASTM D5, D217, D1168, D1191, D1321,
D1403, D1831, D1855; AASHTO T49, T187 and others.

Portable Penetrometer— H-1250
Lighter and smaller than H-1200 for field work, unit’s micrometer adjusts for accurate
settings as well as coarse adjustment for approximate settings. Only one additional 50g
loading weight is included. Overall dim. 7" x 7" x 16" (178 x 178 x 406mm). Shipping wt.

Installation
Level the instrument carefully by means of the leveling screws on the base, sighting
the spirit level from above to obtain accurate alignment. After the instrument has been
leveled, avoid shifting its location. Otherwise it will be necessary to repeat the leveling
process.
Insert penetrating needle or cone into the chuck and tighten the chuck screw.
Set the zero reference. Grasp the gear rack knob and pull up to release the clutch trigger.
With the trigger released, raise the test plunger as high as possible. If the dial reading
is not exactly zero, adjust the reading to zero by means of the zero setting screw (which
is on the bottom of the dial housing) which is adjustable as required. Use a #8 Allen
Wrench.
Procedure
Add the required weights to plunger head. In adding weights and in order to make
up the required load for the test, note that the weight of the test plunger itself is 47.5
grams. For example, when the specified load for grease penetrations involving the use
of a grease cone is 150 grams, no weights need be added to the plunger head since
the combined weight of the cone (102.5 grams) and test plunger (47.5 grams) makes up
required load as specified by ASTM. Place a prepared sample in position on base.
Adjust the height of the mechanism head via the control sleeve on the main post so as
to bring the point of the penetrating instrument exactly into contact with the surface of
the sample. To adjust the height of the mechanism head, release the lock screw. This
adjustment may be accomplished more easily by placing a weak light to one side of the
sample container and observing the shadow formed by the penetrating instrument on
the surface of sample, until light disappears from the point. BE SURE TO RELOCK THE
HEAD SECURELY BY MEANS OF THE LOCK SCREW AFTER THE HEIGHT ADJUSTMENT
IS COMPLETED.
Release the test plunger, allowing the penetrating instrument to descend into
the sample. To release the test plunger, depress and hold the clutch trigger
in its released position during the specified time required for the test. Use a
stopwatch to verify release duration.
CAUTION: In operating the clutch trigger, grasp the finger grip firmly with the
forefinger, and with the thumb depress the clutch trigger quickly as far in as it
will go. HOLD THE CLUTCH TRIGGER IN DURING THE SPECIFIED LENGTH OF
THE TEST. At the specified duration, let go of the clutch trigger quickly, allowing
it to lock the test plunger instantly.
Reading Penetration
To read the depth of penetration, push down the gear rack knob gently as far as it will go.
The dial reading now indicates the depth of penetration directly in tenths of millimeters.
For example: If the pointer comes to a rest at the fourth mark past the 270 point, the
depth of penetration is 274 tenths of a millimeter or 27.4 millimeters.
With the Universal Penetrometer, penetration measurements can be made to a total
depth of 40 mm on a single reading. On depths greater than 40 mm the dial pointer
makes a complete revolution and moves past the zero position for a fraction of another
revolution. Simply add the fractional revolution to determine the total depth of
penetration.
Return the dial pointer to zero, as directed in the Installation paragraph. If the original
zero setting has been accurate, the dial pointer will return exactly to zero and subsequent
readings will check against standard gauge blocks.
We also supply a 15-gram test plunger – readily installed or removed
CAUTION: Keep hands, clothing and other objects away from moving parts when the
machine is in operation.
