The Digital Ink Rub Tester uses the Sutherland-method and is designed to measure scuffing or ink rub resistance. Several tests can be performed including dry rub (the amount of transfer ink from one dry surface to another), wet rub (the amount of transfer of ink from wetted surface to another), wet bleed or transfer (ink transfer to a water-saturated blotter), wet smear (similar to wet bleed with the addition or rub cycles), functional rub/wet rub (smear or transfer tests using a liquid other than water and hot abrasion).

United’s Tru-Blue II is an all scale computer-controlled Rockwell hardness tester utilizing a precision load cell for accurate force measurement. Tough, durable and easy to use. Removable clamping device allows for supporting odd shaped and large heavy parts.
