Your Elcometer Krebs Viscometer is packed in a cardboard and foam package. Please ensure that
this packaging is disposed of in an environmentally sensitive manner. Consult your local
Environmental Authority for further guidance.
1.2 Standards
Your Viscometer can be used in accordance with the following National and International
Standards:
•
AS/NZS 1580.214.1
•
ASTM D 562
•
ASTM D 1084-C
1.3 Krebs units
The Elcometer Krebs Viscometer is suitable for measuring in Krebs units (KU) the viscosity of
paints, varnishes, adhesives, pastes, liquid inks and other similar substances.
The Krebs unit scale is commonly used to refer to viscosity or consistency of paints that are applied
by brush or roller.
The Krebs unit is defined by following equation:
•
For viscosity in the range from 200 cP to 2100 cP
KU = 1.1187 + 0.8542 ln ( 0.1938 v + 36 ) - 0.0443 [ ln ( 0.1938 v + 36 ) ]
•
For viscosity in the range from 2100 cP to 5000 cP
KU = 1.8118 + 0.596 ln ( 0.1938 v + 36 ) - 0.0206 [ ln ( 0.1938 v + 36 ) ]
where:
•
KU is viscosity in Krebs units
•
v is viscosity in centipoise (cP)
Note: The equivalent viscosity in cP given by the instrument should only be used for comparison
between one sample and another; it must never be used for quantitative measurement of viscosity.
To maximise the benefits of your new Elcometer Krebs Viscometer please take some time to
read these Operating Instructions. Do not hesitate to contact Elcometer or your Elcometer
supplier if you have any questions.
2 CAUTION
The Elcometer Krebs Viscometer has been manufactured with your safety in mind.
However, improper use can result in damage to the machine.
Please observe the precautions discussed in these operating instructions.
•
To reduce the risk of electric shock, do not open the Viscometer. There are no
user-serviceable parts inside.
•
To reduce the risk of fire or electric shock, do not expose the Viscometer to rain or excess
moisture.
•
The mains plug on your Viscometer may be fitted with a fuse. When replacing this fuse, ensure
a fuse of the correct rating is used.
•
Do not use the Elcometer Krebs Viscometer in hazardous environments.
