✔ Ergonomic handle – Provides sensitive feedback and fatigue-free inspection along kilometers of seams
✔ Rust-resistant steel construction – Extremely durable and resistant to construction-site dirt, moisture and continuous use

Uncompromising safety on flat roofs: Sievert seam tester (Item No. 297551)

The Sievert seam tester (Item No. 297551 / EAN: 7314522975511) is the essential inspection tool for roofers, structural waterproofers and sheet metal workers to perform quality checks in accordance with regulations, DIN standards and trade rules.Even with the most careful hot-air welding of roofing and waterproofing membranes, minor temperature fluctuations, gusts of wind or uneven substrates can go unnoticed and lead to faulty weld seams.

With its specially shaped, angled test tip the Sievert seam tester is guided along the cooled welding edge with light manual pressure. If the tip encounters a faulty bond or a capillary,it can be felt immediately as it slips into the overlap. This makes it possible to locate weak spots in thermoplastic membranes (such as PVC-P, TPO, FPO) or bitumen seams and carry out targeted repairs before building acceptance. The handy handle transmits every irregularity directly to the craftsperson's hand and enables fatigue-free inspection across large roof areas.

Thoughtful features for standards-compliant acceptance

• Clear feedback: Reliably detects open edges and incomplete welds before water can penetrate.
• Ergonomic force transfer: Sits comfortably in the hand and reduces strain on fingers and joints during extended inspection runs.
• Gentle tip design: Designed for maximum inspection precision without risking perforation of the roofing membrane.
• Robust construction: Made from corrosion-resistant specialty steel for years of use on construction sites.
