Product Details

Handheld Stress Tester for Bridges PMT-1000 On-Site Safety Assessment

Rapid, portable stress evaluation for installed steel structures without disassembly.

The PMT-1000 is a handheld indentation stress tester specifically effective for bridge safety assessment. It provides on-site stress values, enabling immediate judgment of structural overload and stress distribution analysis without removing components.

Its compact design facilitates access to confined spaces, making it an indispensable tool for periodic structural monitoring.

Key Features

Handheld portability – designed for rapid field use on bridges and pressure vessels.
On-site stress output – immediate stress values for overload detection.
No disassembly required – obtains stress distribution data while structure remains intact.
Periodic tracking – enables regular stress monitoring of in-service equipment with minimal damage.
Micron-scale indentations – leaves only 60–120 µm deep marks that are easily removable.
Wide material support – compatible with well-known structural materials like stainless steel and aluminum alloy.

FAQ

Q: How long does a single measurement take?

Typically only minutes, as evidenced by case studies, allowing efficient assessment of multiple locations.

Q: Can it be operated in confined spaces?

Yes, its handheld design and compact size make it suitable for confined areas commonly found in bridge structures.

Q: Does it require any special training?

Basic instruction is recommended, but the device is user-friendly for field technicians.

Q: What kind of data does it provide?

It outputs stress values on-site, which can be used for immediate overload judgment and further analysis.

Q: Is it suitable for aluminum structures?

Yes, it can test aluminum alloy, making it applicable to various bridge materials.

Q: How is the indentation removed?

Indentations are very shallow and can be easily removed by brushing or light sanding.
