DM4, DM4DL Thickness Gauge

The DM4 series enables you to accomplish a large number of demanding tasks, especially with remaining wall thickness measurements on components subjected to corrosion and erosion.

The DM4 and DM4DL are smart, simple-to-use ultrasonic thickness gauges that offer big ultrasonic performance in a small lightweight package. Compact size and ergonomic shape provide comfortable one-hand use.

DM4, DM4DL Thickness Gauge Products Features

• Equipped with a membrane keypad and an impact-resistant, dustproof and watertight housing to guarantee long-lasting and reliable operation
• Field-proven features such as Minimum Capture Mode, Differential Mode and 2-Point Calibration
• Variety of application for the most different materials is made possible by the large selection of probes including intelligent dialog probes for optimized setting and improved performance.
• Automatic probe zeroing for optimized gauge setting to a large number of probes and test conditions
• DUAL MULTI operating mode for accurate wall thickness measurement on painted or coated pipelines and tanks. Any time-consuming and cost-intensive removal of the coating is no longer needed
• Data logger for storing up to 5,000 thickness readings for later download to software for viewing, printing reports and digitally storing data.
• UltraMATE software for data management (DM4-DL only)

DM4, DM4DL Thickness Gauge Applications

The DM4 instrument series are suitable for numerous test tasks on components subject to wear:

• Pipelines, pressure vessels, gas cylinders, storage tanks, vessels for chemical processes
• Materials handling systems, pumps
• Bridges, hulls, cranes, equipment for shipbuilding and structural steel engineering

High temperature probes for temperatures up to 600°C enables you to perform thickness measurements on extremely hot components.
