Summary
The instrument is designed and made asper the National Standard of
Peoples Republic of China GB/T ********0 Standard Test Method for
Penetration of Bitumen, GB/T**9 Test Method forCone Penetration of
Lubricating Greaseand Petrolatum and T********1 Asphalt Penetration
Test in the Industrial Standard of Peoples Republic of China
JTGE******1 Specifications and Test.Methods of Bitumen and
Bituminous Mixturefor Highway Engineering as well as ASTM D5
Standard Test Method for Penetration of Bituminous Materials and
ASTM D**7 Standard Test Methods for Cone Penetration of Lubricating
Grease. It is mainly used to determine the needle penetration of
bituminous mixture and cone penetration of lubricating grease
(orpetrolatum).It is also suitable to determine
solidparticle,powder, colloid andraw-food materials such as
cheese,glycine,butter,creamand leavening.It can be widely used in
food industry,highway engineering and other
industrialfields.
Main technical features
1.It adopts digital display to show the penetration
number.Easytoobserve.
2.Six grade softiming control.High timing control
accuracy.
3. The needle holder can be adjusted roughly and finely. It is
convenient to adjust and exact to aim.
4.Equipped with grease masher and constant temperature bath. The
temperature in bath can be controlled automatically.Multipurpose
and high cost performance.
