Dynamic rotating friction coefficient tester

1Dynamic rotating friction coefficient testerExecution standards:

satisfyIndustry Standard JTG E60 of the People's Republic of China-2008Regulations for On site Testing of Highway Roadbeds and PavementsT0968-2008Test method for determining road friction coefficient

IIScope of application: This instrument is suitable for measuring the dynamic friction coefficient between two relatively sliding surfaces, such as road surfaces, indoor floors of buildings, and even narrow aisle entrances and exits. The surface friction coefficient can be accurately measured using this instrument.

IIIInstrument features:

1Fully automatic measurement: accurate and reliable, completely eliminating uncertain errors caused by human factors.

2Short measurement time: The measurement time required to complete three parallel tests at each test point is no more than 120 seconds.
