1.1 Overview
The Tinius Olsen MP1200/MP1200M Extrusion Plastometer (Melt Flow Indexer) with
microprocessor-based Model MP1200 Controller/Timer, is used for measuring the flow rates
of thermoplastics. The unit is a dead-weight piston plastometer with which the extrusion rate
of thermoplastic materials through an orifice of specified dimensions is determined under
prescribed conditions of temperature and pressure in accordance with ASTM Standard Test
Method D1238 & ISO 1133-1 & 2. With minor procedural or equipment modifications, the
MP1200 can also meet BS 2782, DIN 53735, JIS K7210 and other similar standards;
including ASTM D2581, D3364, D4203, D4507 and D4550 (a special orifice is required for D
3364). Other methods, such as D2116, D3159, D3275 and D3307, require the optional
corrosion resistant cylinder, orifice and piston foot.
A basic machine (MP1200) may be used for Procedure A - Manual Operation. A weight (s)
will be required to apply the test load. The amount of load is material dependent, so
weights are sold separately. With the addition of optional accessories (PPDT), Procedures
B & C (ASTM D1238 Procedure C) - Automatically Timed Flow Rate Measurement for Melt
Flow Rate (MVR) and/or Melt Volume Rate (MVR) can be performed.
The MP1200M is equipped with a motorized Weight Lifting/Lowering Device (WLD). It can
also be used for Procedures A, B, C & D when equipped with the optional PPDT (Flow Rate
Ratio Attachment is required for Procedure D). A weight(s) will be required to apply the test
load. The amount of load is material dependent, so weights are sold separately.
CAUTION: This instrument has been designed to determine the flow rate and other thermal
processing properties of polymers. It is not intended for any other use. Any attempt to use
this instrument in any fashion other than its intended use may void the warranty, damage the
machine and/or harm the operator.

1.6 Precision Three Zone Band Heater
310 Watts (nominal) -- contains a special concentric heating element, which is form-fitted
and designed to uniformly maintain the required temperature. The heater and furnace
assembly is rated for use up to 450°C. Three platinum RTD Probes sense the cylinder
temperature, sending signals to the MP1200 Controller, which regulates the temperature of
the upper and lower portions of the cylinder to within ± 0.1°C. The temperature of the lower
portion of the cylinder is displayed as the Actual Temperature (AT).
1.7 Test Results
For Procedure A type tests, Flow Rate (Melt Index) is calculated and displayed for each cut-
off. When Procedure B type tests are performed using the optional PPDT Automatic Timing
Switch, Flow Rate (MFR), and Volume Rate (MVR) may be determined and Apparent
Shear Stress, Shear Rate and Viscosity, and Volume Rate can be selected for calculation
and display. Melt Density may be entered or calculated from cut-off weight. Average
values are calculated when more than one measurement is made during a test.

Note: The MP1200 monitors the incoming line voltage and automatically compensates for small
changes in the line voltage. However, major line voltage problems (spikes, surges,
dropouts) will have to be addressed externally by the user. A qualified electrician should be
consulted and employed should it become necessary to install isolating/regulating
transformers, etc.
The line filter used in the Power Entry Module typically has a leakage current of 0.25 mA to
ground at 115 VAC, and 0.5 mA at 220 VAC. This current leakage may cause a Ground
Fault Interrupt (GFI) receptacle to trip, therefore a GFI is not recommended.
A standard computer grade surge suppressor is recommended for protection.

2.2.3 Navigation Keys
2.2.3.1 Navigation -
Used to access the motorized weight lifting/lowering device (WLD) functions and
purge/purge & clean functions. This key only appears if the WLD or Purge or
Clean functions are turned on in the Configuration Mode.
2.2.3.2 Test Mode
The Test Mode allows the operator to run a test. The operator will have to select
a program from the file list that appears after pressing on the check mark next to
the FILE box. The MP1200 comes from the factory with 7 sample programs
already entered. It is unlikely that any one of these example programs will be an
exact match for the material that is to be tested. They are meant as a starting
point and should be fine tuned the user’s needs. Users may program their own
test before using the Test Mode by using the PROGRAM button on the display
(see instructions below). When properly programmed, the display will indicate
the parameters of the test. The selected program prompts the operator to enter
the necessary information when starting a test, alerts the operator to perform
tasks that may be necessary during the test, prompts for any information that
might be necessary after the test, and then calculates and displays test results.
2.2.3.3 Program
The Program mode allows the operator to select the parameters of the test. The
mode is password protected. The operator can create and store new programs,
select existing programs, edit existing programs or delete programs.
2.2.3.4 Results
The Results mode is used to recall, review and/or print stored test results. For
“Procedure A” type tests, the Flow Rate (Melt Index) is calculated and displayed
for each manual cut-off. When Procedure B type tests are performed using the
optional PPDT Automatic Timing Switch, the Flow Rate (Melt Index), apparent
Shear Stress, Shear Rate and Viscosity, and Volumetric Flow Rate (MVR) can be
selected for calculation and display.
2.2.3.5 User Settings
The User Settings mode allows the operator to select the optional printer, turn
alarms on and off, adjust the volume of alarms, select units, adjust the brightness
of the screen and adjust the Calibration Offsets. The operator can also send logs
to a USB thumb-drive and set the date and time. The mode is password
protected.
2.2.3.6 Configuration

Operation Manual # 02002215
2.3 Three-Zone Temperature Control
The temperature controller features three-zone proportional, integral, and derivative (PID)
control, assuring spatial temperature variations of less than ± 0.25°C along the test area of
the cylinder. Temperatures up to 450°C are controlled and displayed to ± 0.1°C; utilizing
three platinum RTD’s embedded in the cylinder wall. The controller also has built-in
temperature sensor recognition indicator. If an RTD opens or shorts out (or temperature
control becomes erratic), power to the heater is interrupted and an error message is
displayed.
2.4 Timing Systems
Timing functions up to 999 seconds are available for preheat timing, cut-off intervals,
operating a WLD, as well as other optional features. Piston displacement timing is
displayed in 0.01 second increments up to 1000 seconds and in 0.1 second increments
from 1000 to 3600 seconds. An audible alarm can be activated which will prompt the
operator to perform functions such as applying the load, cutting off the extrudate, etc.
2.5 Communications Port
The test information and results can be sent directly to an optional printer or the machine
can be interfaced to a computer utilizing the serial Communications Ports (USB and EIA-
232) provided as standard. Up to ten machines can be interfaced to a single computer
2.6 Multiple Data Determinations (Captures)
The MP1200, when equipped with the optional PPDT gives the operator the ability to make
up to 10 individual flow rate/volume rate (melt index) determinations within a single sample
charge when performing a test to ASTM Procedure B. While this feature is not required by
ASTM D 1238, it is required for ISO 1133 testing. It can also be useful for checking the
consistency of results and in improving accuracy by isolating sources of error such as air
bubbles and allowing the operator to eliminate obviously flawed data. The multiple capture
features may be used with any material, but it is most often used with materials that have
flow rates greater than 10 g/10 minutes. A typical example of the test parameters used for

Operation Manual # 02002215
3 Section 3 –Operating Tools
The following tools are included with each MP1200 as standard equipment. Refer to Figure 3-1 for
an illustration. See Section 16 for cleaning instructions.
IMPORTANT: All these tools are made of materials that are softer than the cylinder. This is to
prevent any scoring or damage to the walls of the cylinder. If the cotton cleaning patches
cannot effectively clean the cylinder walls, an optional 0.406” diameter soft brass brush
(available from Tinius Olsen) can be used to help clean the cylinder.
One (1) ASTM Piston Assembly (Items 1A, 1B & 1C, Figure 3-1) - consisting of a
removable stainless steel piston foot (P/N: 02001086); piston guide collar (P/N:
02002149); and ASTM piston rod (P/N: 02002163). The piston rod and foot weighs
100 grams (not including the guide collar). It is considered the first 100 grams of all
test loads.
One (1) Charging Tool (P/N: 02001582), is used to compress the test material down into the
cylinder (cylinder bore), and helps to remove some of the entrapped air when
charging material. Provided with a replaceable tip (P/N: 02001071).
Two (2) ASTM D 1238 Orifice (die), D2 tool steel (P/N: 02001030).
CAUTION: Machines supplied with a nickel-chrome alloy bore should not be used with the
standard tool steel die. Please use either the carbide or satellite die options.
One (1) Level (P/N: 02001271) - used to check the Cylinder Alignment (Level) of the
cylinder. This level is made to fit over the end of the Piston Rod Assembly, with the
piston and orifice in the cylinder.
One (1) Stainless Steel Funnel, (P/N: 02002155) - is used to help introduce a sample of
material into the cylinder.
One (1) Cylinder Cleaning Tool, (P/N: 02001527) is used to clean the cylinder after each
test with the cotton cleaning patches.
One (1) Cutoff Tool, (P/N: 02001090) this U-shaped tool is used to cut-off the extruded
sample at the bottom of the orifice.
One (1) Orifice Drill, (P/N: 02002193) this soft drill bit is used to clean material out of the
inside diameter of the orifice.
CAUTION: The tools used on the machine may get hot during use.
