Technidyne Pulmac Automated Z-Span™ Fiber Strength Tester

Measure fiber strength before quality slips 

The Technidyne Pulmac Automated Z-Span™ Tester tells you whether your fiber is strong enough to run — before you find out the hard way on the paper machine. Load handsheet or strip samples onto the feed tray, and the system automatically runs up to 24 wet and/or dry tests in a single sequence. 

Results appear on the touchscreen interface within minutes and export directly to a PC database for trending and record keeping.

Detect process changes before quality declines

Weak fiber means web breaks, lost production time, and downgraded product. The Z-Span™ Tester generates fiber quality numbers sensitive to fiber strength, fiber length, bonding potential, and fiber alignment — the variables that determine whether your sheet holds together on the machine. 

Routine testing catches process drift early, so you can adjust before quality drops and production pays the price.
