function:

1)DSHD-0613A  Automatic Fraass Breaking Point Tester is designed and developed as per T0613 “Asphalt Breaking Point Test (Fraass Methods) in the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering. The instrument is applied to determine Fraass Breaking Point of bituminous materials.

2)DSHD-0613A  Automatic Fraass Breaking Point Tester can make determination for 3 pieces of samples at the same time, and calculate the average value of three test data. It uses computer to control cooling rate and is equipped with a printer to print out test data and a RS232 output port.
