l This instrument is used to determine the temperature which a bitumen tends to break rather to flow when cooled and stressed as per standards GB/T 4510 and JTG E20-2011.
l It can do three tests at the same time in the same environment and calculate the average value. The cooling rate is controlled by computer.
I. Features
l It is controlled by micro computer. The cooling rate is controlled automatically.
l It automatically timing to bend samples. The test data is shown on the colored LCD and outputted by built-in printer.
