Proceq Profometer

The Proceq Profometer is an electromagnetic rebar locator and cover meter used for non-destructive measurement of reinforcement position, spacing, diameter and concrete cover. The current Profometer range (PM-630 / PM-650 AI) supports both single-pass cover measurement and gridded area scanning, with the AI variant providing on-instrument bar-diameter estimation via a trained classifier. Maximum cover-depth detection is approximately 185 mm (large-bar mode) with stated accuracy of ±2 mm to 60 mm cover. Data export is via the Proceq Inspect cloud platform and PROFOMETER PC software, supporting structured reporting and multi-survey comparison.

TRSC Application Commentary

TRSC uses the Profometer as the alternative to the Hilti PS 300 on investigations where the Proceq cloud workflow is preferred (typically when reporting must be co-coordinated with parallel Schmidt-hammer or UPV surveys collected on Proceq Pundit / Schmidt instruments via the same Inspect platform). The Profometer's strength is the integrated scan-to-report pipeline: a Quickscan or gridded scan can be tagged with the structural element ID, exported to Inspect, and overlaid against parallel Schmidt-rebound or chloride-profile data without manual re-entry. This matters on large facade or slab investigations where 50+ scan locations may be captured in a day and manual re-keying introduces transcription error. Operationally the Profometer behaves similarly to the Ferroscan: TRSC calibrates against a known exposure point per investigation, particularly on saturated or chloride-contaminated concrete; we use Imagescan mode for pre-coring verification and Quickscan for linear cover-depth surveys; we cross-check Profometer readings against GPR for any cover above 100 mm. The PM-650 AI bar-diameter classifier is treated as an indicative reading only — for diameter-critical decisions (residual capacity calculation, strengthening specification) TRSC requires either a bar-exposure verification or a calibrated NDT-plus-coring pair. Recent field deployment includes 140 William Street facade-cover survey where Profometer + Pundit UPV results were collected in parallel and synthesised in a single Proceq Inspect dataset. The Inspect cloud workflow also supports parallel-survey handoff to the asset owner — the dataset can be shared with the client's own engineering or facilities team for follow-up tracking, which TRSC has used on long-term monitoring engagements where the client retains visibility of the same dataset that supports the engineering interpretation.

Frequently Asked Questions

Application questions about Proceq Profometer

Why does TRSC use the Profometer alongside the Hilti PS 300 Ferroscan?
The two instruments are functionally similar; the choice on a given investigation is driven by the reporting workflow. When TRSC is also collecting Proceq Schmidt-hammer or Pundit UPV data, the Profometer integrates into the same Proceq Inspect cloud dataset, eliminating manual transcription. When the investigation is GPR-led, the Hilti PS 300 pairs more naturally with the Hilti PS 1000 in a single PROFIS export.
How reliable is the AI bar-diameter classifier on the PM-650?
For single-bar, clear-spacing geometry with cover ≤60 mm, the AI classifier produces useful indicative results. For congested reinforcement, twin-mat layouts, or any cover above 100 mm, TRSC treats the diameter result as indicative only and verifies via bar exposure or calibrated NDT-plus-core where a diameter-critical decision is being taken.
Does the Profometer require licensing or operator certification?
No specific operator licensing is required for the electromagnetic instrument itself. TRSC operators are RPEQ-supervised and trained in cover-survey methodology consistent with BS 1881-204 procedures and the AS 3600 cover-verification framework that informs structural assessment.
