Ⅰ. Introduction

• GD-2801F Low Temperature Asphalt Needle Penetration Tester 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.

• GD-2801F Low Temperature Asphalt Needle Penetration Tester is used to determine the penetration of pavement petroleum asphalt, modified asphalt, liquid petroleum asphalt and emulsified asphalt.

• GD-2801F Low Temperature Asphalt Needle Penetration Tester 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. 

 

 

Ⅱ. Main Features

• It adopts digital display to show the penetration number and two grades of timing control.

• 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.
