• Over 10 hours battery life.
• Secure harness points for rope access work.
• Touchscreen functionality available.
• Auto-detect probe feature.
• Record/replay, marker placement and defect sizing.
• Trace feature – Butterfly / Bx / Bz.
• Measures the length and depth of each crack.
• No surface cleaning required – inspect straight through coatings.
• Two year warranty, extendable to 5 years with ETherCover.

Overview

Alternating current field measurement (ACFM, which ETher NDE calls ACFMT) is an electromagnetic method related to eddy current testing. The probe puts a small, even current into the metal surface. Sensors measure how a crack disturbs that current. The instrument then works out the crack’s length and depth. The ACE has a 7-inch screen you can read in any weather, so one person can carry out crack checks on site or offshore.

Common applications

• Rope access inspection
• Weld and pipeline weld inspection
• Cranes and towers
• Refinery piping and vessels
• Painted and coated structures
• Bridges and infrastructure
• Rail wagon integrity
• Topside offshore / onshore structures

ACFMT probes

Designed and manufactured in-house by ETher NDE, probes are available at 5kHz for ferritic (carbon steel) welds and 50kHz for austenitic (stainless steel) welds. Every probe has integrated Start/Pause, Stop and Change Direction buttons for single-operator use, and stores its own configuration. The Weld Probe has a large drive coil for the most accurate sizing on deep defects, while three Pencil Probes (straight, 90° inline, 90° transverse) reach tight geometries and perform better at plate edges.

Software & reporting

The ACE-R reporting software turns any data set into a report with location information, data traces, defect sizes, site notes, probe/instrument details and an inspector sign-off box in just a few key presses. Reports export as .pdf or .docx, and full scan records are kept for audit tracking.
