Elmendorf tearing tester (digital display type)

This machine is designed to measure the resistance to tearing of various kinds of printing paper such as newspaper, paper bags, packing paper, when subject to tearing stress during their use. Usually, tear resistance is composed of force of extracting fibers from paper layers and force of cutting the fibers. In general, the longer the fiber length is, the stronger tear resistance is. When the binding area among fibers increases, exceeding the optimal area, the tear strength decreases inversely with the trends of tensile and bursting strengths. This machine with an additional weight on (option) is able to measure a wide range of materials, including paper, paperboard, fibers, plastic film and the like. With a pneumatic specimen clamp, the system is excellent in operation, displaying an average measurement for a unit of 16 sheets.

Elmendorf tearing tester (digital display type)

Specifications

Pendulum capacity	standard type: strength 0 to 1,000mN per specimen heavy-duty type: strength 0 to 2,000mN per specimen The capacity of an added weight （optional） can be changed with the capacity-setting switch.	Precision	±1%
Specimen clamp	pneumatic clamp with a push button	Mumber of specimens	Set the number of specimens laid one on the top of another. The numbers of specimens set are 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 16.
Input of a basis weight	Inputting of a basis weight enables to determine the specific tear value.	Error warning	When the tear value is not included in the range of 20 to 80%, the error lamp warns of this event.
Pendulum friction display	Announces whether or not the rotation friction of the pendulum is in an allowable range.	Automatic setting of the zero point	While the pendulum swings automatically, pushing the zero setting switch allows automatic correction.
Data display	The data of tear value and tear ratio are shown by pushing the changeover switch.	Switching display	SI unit (N) and gram unit (g) selectable
Data output	When the tear value is not included in the range of 20 to 80%, the error lamp warns of this event.	Power source	100/110VAC 50/60Hz 1A
Air source	0.5 to 0.6MPa	Outer dimensions	520×370×660mm
Instrument weight	22kg
