The Z-Span™ Tester generates repeatable zero and short span tensile test data.

The Z-Span™ manual bench top tester measures zero and short pan tensile strength with individually loaded handsheet or machine made paper samples. The Z-Span™ Tester generates individual tensile readings from prepared test strips. The Dial-a-Gap attachment facilitates testing at multiple spans from 0.2 mm to 0.6 mm. The West Testing Kit supports sample preparation and testing of re-wet test strips.

Features include: Data sent by Ethernet to data logging software, LCD touchscreen control panel and a service mode.

Zero span tensile testing remains the benchmark for measuring Fiber Strength. The Z-Span™ Tester conforms to all national and international test methods. This classic tester has been enhanced with new features to make data output more accurate and operation simpler and trouble free.
