Asphalt wax content tester

main feature:

The petroleum asphalt wax content measuring instrument is an automatic method developed by our factory according to the “Standard Method for Analysis of Wax Content of Petroleum Bitumen” issued by China Petrochemical Industry Corporation, SH/TO425 “Experimental Method for Wax Content of Bitumen” (Distillation Method). Special instrument for constant temperature and refrigeration petroleum asphalt content. This instrument complies with the JTG E52-2011 standard of the Ministry of Communications.

The temperature control part adopts digital electronic temperature control table chiller with high precision, fast reflection and clear reading. It is imported 15KW, F22 high power compressor, and deep cold can reach -28 °C. It solves the shortcomings of the previous use of artificial dry ice cooling, temperature caused by Dewar insulation is not easy to control, can only do one sample at a time, and difficult to analyze and test.

The petroleum asphalt wax measuring instrument can perform analysis test of three samples at a time. It has the advantages of rapid cooling, high control precision, easy operation, time saving and so on. It is an ideal analytical instrument for petroleum, chemical, construction, highway construction and other industries.
