Dual Excitation Mode & Ergonomic Design

EsaPort is the only portable OES platform that switches in a single instrument from fast scrap sorting to precise PMI testing. Aluminium/PTFE housing and a 3-metre fibre optic cable adapt to any environment.

Argon-Free DC Arc
Rapid scrap sorting and first-pass identification outdoors or at points without an argon supply.
🎯
Argon Spark
Precise measurement for production-line PMI and quality approval. E4 Plus includes P and S determination.
🔧
Special Geometry Adapters
Wires, small parts, curved surfaces, and weld seams — analysis on any geometry that does not fit a standard stand.
GNR EsaPort E3

400 Wh Battery — Off-Grid Analysis

Approximately 2 hours of continuous full-performance operation at field points without mains power. Autonomous analysis maximises efficiency on site.

🔋
400 Wh External Battery Pack
Optional 400 Wh battery delivers full-performance analysis at remote yards and warehouses where mains power is unavailable.
🎯
Automatic Profile Adjustment
Stable measurements unaffected by temperature changes. No calibration drift in heavy factory or outdoor conditions.
💻
Integrated Touchscreen
EOS® software, results, and reports ready in the field on an integrated INTEL NUC — no external PC needed.

What People Ask

The E4 Plus is lighter (15 kg vs 23 kg), covers a wider wavelength range (178–460 nm), and can analyse Phosphorus (P) and Sulphur (S) in the field thanks to its dedicated argon-purge probe. The E3 combines arc and spark excitation, making it a powerful and cost-effective choice for standard PMI and scrap sorting.

The optional 400 Wh external battery pack provides approximately 2 hours of continuous analysis in the field without mains power.

Yes. Specially designed geometry adapters allow high-accuracy analysis on non-flat surfaces, wires, small parts, curved surfaces, and weld seams.

PMI (Positive Material Identification) is a non-destructive test that confirms a material is genuinely the specified alloy. It is critical for preventing pipeline failures, pressure-vessel rupture risks, and quality non-conformances caused by wrong material use.
