MFT-R4000 high speed reciprocating friction wear tester

MFT-R4000 is a multifunction tester used for evaluating the high speed reciprocating friction and wear performance of materials and films under different environment with variation of load, frequency, temperature and gas. It is also applied in the friction and wear measurement under corrosive solution, mainly simulating the conditions of sea, river, lake, and body fluid, etc..
