This instrument offers an easy method for the determination of film hardness for coating applied to a flat substrate. The pencil lead, prepared beforehand by rubbing it on fine abrasive paper（400）,is maintained at an angle of 45º and pushed with uniform pressure onto the sample, either leaving a superficial trace or causing destruction down to the substrate. It complies with the requirements of ASTM D 3363, ISO 15184. 

Furthermoe, Biuged also offers BGD 506/2S whose all materials are stainless steel. Besides all characteristics as above, BGD 506/2S can lock pencil automatically and the block for adjusting leve is designed as monolithic construction.  which is convenient for operator to install and remove pencil and adjust working level, more easily and faster!
