Automatic Large Touch Screen Marshall Stability Tester
imported color large screen PLC controller,directly display the stability value,flow value,curves,results and test time.
It can automatically measure,calculate and process to kinds of test data,and realize the automatic and intelligent operation during the test procedure.
I.Summary
This automatic marshall stability tester is designed and made as per ASTM D6927. It is used to do the Marshall stability test and judge the destroy point for bituminous materials.It can do the proportion design of the bitumen mixture and inspect the construction quality of the bitumen road.
II. Main technical features
1.Adopting the advanced technologies including sensor and microcomputer processing,it can automatically measure,calculate and process to kinds of test data,and realize the automatic and intelligent operation during the test procedure.
2.With high precision instrument amplifier and overturn function,imported color large screen PLC controller,directly display the stability value,flow value,curves,results and test time.
3. 100 groups of test data and test time can be stored in the automatic marshall stability tester and call out whenever needed. All procedures will be controlled automatically.
4. RS232 communication port. Realize the communication with upper computer. The data process, store, print and display can be controlled by a PC. Also the test procedures can be controlled by a PC.
5. The automatic marshall stability tester use the advanced plating technology,metal yogon,high hardness,abrasion resistance and durable service.
6.This automatic marshall stability tester also has functions for manual lifting, lowering and stopping. Convenient to use.
