On this machine, we can change sample width, gauge length, and loading rate. Output results are paper strength in force units standard or metricelongation at break as a percent from the original gauge.

Output results are paper strength in force units standard or metricelongation at break as a percent from the original gauge length. The energy consumed to tear the test sample usually 4 d77 of the sheet material a certain distance is used to calculate the average tearing force.

It measures the ability of a sheet of material paper to withstand repeated folding. It is also useful for indicating the deterioration of material upon aging. The maximum force causing failure axtm measured and given in pound. This instrument measures the bending moment required to deflect the free end of a 1.

The resistance to bending is calculated from the bending moment and given in Taber units. The unit uses Scott and American Sisal craft specimen technique.

The TSO Tester is an ultrasonic instrument for measuring Tensile Stiffness Qstm or Tensile Stiffness Orientation properties on sheets in machine and cross directions sheet paper samples. Gurley is the standard instrument for measuring porosity, air permeability, or the air resistance of paper products.

The Hagerty Paper Smoothness Tester tests the surface smoothness of paper especially coated. This method is a measurement of the air flow between the specimen backed by flat glass on the bottom side and two pressurized, concentric annular lands that are impressed into the sample from the top side. The rate of air flow is related to the surface roughness of paper or paperboard.

Its primary application is for coated papers but the machine may also be used on uncoated papers, most ink films, and paper or qstm. The Brightimeter Micro S5 measures brightness, opacity, color, and fluorescence.

The Electronic Micro Gauge measures specimen thickness within the 0 — 3 mm range. In our wet processing and testing laboratory, we have a whole line of machines from wood chip digesters, pulpers, repulpers, mixers, to handsheet paper making.
