Manual Z-Span Tester™

Z Span Tester from Pulmac


The Z-Span™ manual bench-top tester measures zero span and short span 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 0.0 mm to 0.6 mm. The Wet Testing Kit supports sample preparation and testing of re-wet test strips. New features include: Data sent by serial port 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.

Bottom-line: Increased accuracy for a classic test.
