STM-IV(B) Stormer Viscosity Meter Digital Rotating Paint Viscometer Temp Display
1. Summary: The stom
viscometer is used for the determination of paint and other KU
indicating the viscosity of the coating. The instrument can display the
KU value of the measured sample viscosity or the load value associated
with the KU value (unit: G). The instrument is
controlled by a computer. The blade of a stirred blade (also called a
rotor) is driven by a constant speed motor at a speed of 200r/min. The
resistance moment of the impeller in the measured sample is converted by
a computer to the KU value. (Krebs (Krebs) unit (KU) is a logarithmic
function of the load required to produce 200r/min speed, which is
generally used to represent the speed of the 200r/min. It is used for
the viscosity of the brush and roll. The operator only needs to enter
the stirred blade into the measured depth and read the KU value of the
sample or the relative load value directly from the instrument. The
operator is simple and convenient to operate. The rotor is not needed to
change the rotor in the whole measurement range (the rotor is the main
part of the connection sensor, the improper installation will affect the
measurement accuracy). This instrument is in accordance with the
ASTM-D562 and GB/T9269-2009 standards. Two. The main technical parameters: 1. Measurement range: 40.2 ~ 141.0KU (KU value), 27cP-5250cP 32 ~ 1099g (load value); 2. Measurement accuracy: 1.50% of full range; 3. Measurement repeatability: the full range of 1.50%; 4. The rotational speed of the mixing axis: 200r/min + 1r/min; 5. Container capacity: About 500ml; 6. Input voltage: 110V 7. Power: 10W; 8.Display:Digital 9.Temperature Display: Yes 10.Time Display: Yes 11.RS232C Port: Yes 12.Software: Yes 8. Shape size: 210mm x 180mm x 500mm (L*W*H); 9. Weight: 10kg. Three. Experimental environment: 1.
the instrument should be placed on a strong and smooth surface away
from strong airflow, strong magnetic field, strong electric field and
strong electric pulse interference.
2. in order to ensure the safety of the operator, the power outlet in the laboratory should be grounded reliably.
3.
the temperature in the laboratory should be 23 C + 2 C, and the
relative humidity should be less than 75%.The temperature of the
4. sample should be 23 + 0.2 C.
Four. Operation and use:
1. remove the instrument from the packaging box and put it on the worktable.
2.
remove the stirring blade from the packing box, insert it into the
sleeve of the rotating shaft, and fix it with the top tightening screw.
3.
plug in the power plug, open the power switch on the back, the system
starts to self check, the system will enter the standby state after the
completion of the self test, and the display will display "-".
4. put
the tested sample in the container which the instrument comes from, the
liquid level is about 10mm from the container port.
5. put the
container on the container seat on the container to be tested and select
the unit of measurement ("KU") to indicate the KU value of the sample
to be tested, and "GM" to indicate the load value. Press down the
lifting handle, immerse the stirring blade into the sample to be tested,
and the marking line on the blade axis of the impeller is aligned with
the liquid level, and the instrument automatically starts running.
6.
after a few seconds, the monitor displays the viscosity value of the
sample to be measured, which can be read at this time. (the sample must
be stirred for a few seconds to achieve dynamic balance, and the data
displayed can be considered accurate, without the display of the data
before the instrument "--").
7. after the measurement is completed,
the lifting handle is lifted to the height, and there is a limited bit
device near the highest position, so that the instrument can always be
kept in this position. The instrument stops turning and reenters the
standby state.
8. the instrument has built-in smart display
stabilisation program, so that each reading is stable and readable to
the operator. If you want to measure different units of measurement
without shutting down, just switch the selector switch to the unit of
measurement you need.
Five. Note:
1. there are precise measuring parts in the instrument cabinet.
2.
this instrument is a special instrument. Please do not open the
instrument shell by itself, so as not to affect the accuracy of
instrument measurement.
When the 3. instruments are temporarily
unused, the lifting handle of the instrument should be kept on the high
position limit unit, and it should not be placed in a lower position,
otherwise the phenomenon of inflexibility may be produced.
4. every year, companies should be checked regularly or sent to the metrological supervision department for testing once.
