Summary
This instrument is designed and made as per T0604-2011 Penetration Test for Bituminous Materials in JTG E20-2011 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering and ASTM D5 Standard Test Method for Penetration of Bituminous Materials. It is used to determine the penetration of pavement petroleum asphalt, modified asphalt, liquid petroleum asphalt and emulsified asphalt. It is also suitable to test solid particle, powder, colloid and raw-food materials such as cheese, glycine, butter, cream and leavening. It can be widely used in food industry, highway engineering and other industrial fields.
I.Main technical features
1. It adopts digital display to show the penetration number and two grades of timing control.
2. Specially designed low-temperature circulatory water bath can supply the constant temperature water into glass bath on the penetrometer. It creates a constant low temperature which can be preset for the specimen.
