Rohmann ELOTEST M2 LS V2 Portable eddy current flaw detector for non-destructive testing (NDT)

Versatile Dual-Frequency Eddy Current Inspection

The Rohmann ELOTEST M2 LS V2 is a portable eddy current flaw detector designed for fast, repeatable surface and subsurface inspection across conductive materials. This second-generation system integrates the ELOTEST M2 handheld flaw detector with the M2-LS Base Unit, which provides Lift-Off Suppression electronics and power-supply functions for bench or field operation.

Why It Helps

Operating on Firmware 2.10 and the M2-N14 analog platform, the V2 delivers stable signal processing for non-destructive testing of rivets, fasteners, welds, and thin-wall components. The M2-LS Base Unit’s lift-off suppression circuits minimize phase drift caused by paint or surface variation, ensuring consistent defect visibility even on coated or curved parts.

Key Highlights

• Two-piece system combining ELOTEST M2 handheld and M2-LS Base Unit for portable or stationary use
• Lift-Off Suppression electronics maintain signal stability on painted or uneven surfaces
• Dual-frequency operation from 100 Hz to 12 MHz for surface and subsurface defect detection
• Firmware 2.10 (V2) with M2-N14 analog architecture—fully compatible with legacy Rohmann probes
• Automatic balance, gain, and phase controls with selectable band-pass filters
• Rechargeable battery operation via M2-LS Base Unit or stand-alone mode
• Large LCD display with numeric and graphical phase/amplitude representation

Applications

Ideal for aerospace, automotive, and power-generation maintenance tasks requiring precise crack and conductivity evaluation. Common applications include fastener hole inspection, weld seam testing, turbine blade assessment, and machined-part quality assurance.
