Tribometer GMG-200

Tribometer is a mobile instrument for measuring the coefficient of sliding friction of floorings conforming to DIN standard 51131 and EN 13893. The measuring instrument consists of an active sliding unit, a set of interchangeable sliders, fastening angle for the traction cable and pack of rechargeable batteries. The sliding unit contains the traction mechanism, sliding friction measuring electronics, LED indicators and a battery charger. The slide measuring instrument standard design GMG 200 is for the routine control of sliding friction on various floor coverings. The sliders can be interchanged depending on the floor covering. The material of the sliders, the actual ambient temperature and humidity are also detected and recorded in the report. The LED indicators are a simple users guide, indication of actual working conditions and computed sliding friction coefficients. The integrated data interface RS232 allows a transfer of the measured values to a laptop or a PC, which enables a choice and precise evaluation of the measured traces of curves and deviations from nominal values to be made. A standard report can be printed. The necessary software GMG – VD is separately available. The instrument can store up to 90 measured curves (e.g. 18 measurements each with 5 curves).
– One-hand battery-operated measuring unit robust design
– Measured values and nominal value deviations in clear-text indicator
– Operation display, indication „power on“ and „battery low“
– Free memory , slider materials, temperature and humidity displays
– Simple activation of measuring mode after switching on by pressing the “”Start”” button or by foot operation
– Permanent storage of measuring curves also after unit has been switched off.
– Interface to PC
