172.483 | Seam Weld Tester - multitool
The Leister Seam Weld Tester Multitool is designed for non-destructive testing of overlap welds on thermoplastic roofing membranes such as PVC and TPO. Developed in collaboration with Victorinox, this multifunctional tool combines a precision test probe with practical features including a Phillips screwdriver, bottle opener, fastening ring, and large serrated knife blade.
The redesigned Leister test probe glides smoothly and ergonomically along weld seams without damaging the membrane. If the probe slips into the overlap, a leak has been found and can be repaired. Suitable for both right- and left-handed users, it features an integrated hole that allows for easy one-handed opening—making it an essential companion for efficient, on-site weld inspection.
