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 corrosionerosion.
The DM4DM4DL are smart, simple-to-use ultrasonic thickness gauges that offer big ultrasonic performance in a small lightweight package. Compact sizeergonomic shape provide comfortable one-hand use.
DM4, DM4DL Thickness Gauge Products Features
- Equipped with a membrane keypadan impact-resistant, dustproofwatertight housing to guarantee long-lastingreliable operation
- Field-proven features such as Minimum Capture Mode, Differential Mode2-Point Calibration
- Variety of application for the most different materials is made possible by the large selection of probes including inligent dialog probes for optimized settingimproved performance.
- Automatic probe zeroing for optimized gauge setting to a large number of probestest conditions
- DUAL MULTI operating mode for accurate wall thickness measurement on painted or coated pipelinestanks. Any time-consumingcost-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 reportsdigitally 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 shipbuildingstructural steel engineering
High temperature probes for temperatures up to 600°C enables you to perform thickness measurements on extremely hot components.
