Variable Weight Reciprocating Friction Test Jig

VWF-10N-J
Jig for Coefficients of Friction (COF) test of a Flat Specimen and a Contactor
Enable to handle various samples using different Contactor Holders
Available to create vertical force by weight and reciprocating friction
Optional Software available for automatic calculation of COF

VWF-10N-J

VWF-10N-J*(L) Elevation balance Unit

(R) Table Unit

COF test of a pen using VWF-10N-J** The force gauge, the stand and the contactor holder sold separately.

How to set up
Fix the Flat Specimen to theTable and the Contactor to theContactor Holder.

After fixing the position of theCounterweight to hold the arm
horizontal, rotate the handle ofthe Elevation balance unit tomake the Contactor touch theFlat Specimen.

Put weight on the weight plate tocreate vertical force.

Set up the measuring speed
and then start themeasurement
