Paper and board -- Determination of roughness/smoothness (air leak methods) 

  • TMI 58-07 Parker Print-Surf (Dual Head)

    A microprocessor-controlled instrument, which performs high speed, precision measurements of paper surface roughness under conditions that simulate those encountered during the printing process.

  • TMI 58-24 Monitor Smoothness II Sheffield

    Designed to work with existing smoothness and porosity heads. It provides an inexpensive means to improve measurement accuracy, and to remove old style mercury-based measuring systems.
