Purpose:
This Automatic Petroleum Bituments Breaking Point Tester is suitable to the standard of GB/T4510 and T0613-1993. Test the temperature of bitumen when bitumen appear crack under the condition of cooling and bending. Operate three same experiments under the same environment. Automatically check and calculate the average value of three results. Temperature descending speed is controlled by computer. Inner printer prints the results of the experiment.
Technical Parameters: 
1. temperature testing range: -30 ∼25
2. Temperature accuracy: 1/min
3. Dimension of steel piece: 41×20×0.15mm
4. Sample number: 3
