BRIEF DESCRIPTION
Brief Description
The GMG-200 is a mobile device for measuring the coefficient of sliding friction of floor cov-
erings conforming to DIN 51131, DIN EN 13893 and DIN CEN/TS 16165.
The device has a traction cable that allows it to draw itself across the flooring to be tested
by an integrated motor. The electronic component of the GMG-200 records the friction and
evaluates it.
The scope of delivery includes a foot plate to which the traction cable is attached. The foot
plate serves as the anchor point during pulling.
To be able to reproducibly evaluate the frictional forces, the GMG-200 is equipped with
sliders that comply with the applicable standards. The sliders are attached to a changeable
slider assembly on the bottom of the device. The slider assembly can be changed as needed
for the respective type of flooring. A sensor incorporated into the slider assembly enables the
GMG-200 to automatically detect the material of the attached sliders and to include it in the
evaluation.
All of the measured values and the signal patterns are automatically placed in the device’s data
memory, which can record up to 90 measurements. The integrated LCD guides the operator
and displays relevant information. The intuitive control panel provides direct access to all of
the core features.
Integrated batteries supply energy to the device; a power supply (battery charger) is included
in the scope of delivery.
A serial data interface in conjunction with the optional Windows software GMG-VD enables
the measured values to be transmitted to a laptop or PC to be evaluated, logged and stored.
