What does the NPA-500 measure?
It resolves fine pore structure: Bubble-point (largest) pore Mean-flow pore size Full pore-size distribution Nominal / absolute micron rating
EXPERIENCE THE most advanced Nanopore Analyzer
M19 Nanopore Analyzer (NPA-500) for defense — AI-based, ultra-high-precision testing. Standards: ASTM F316, ASTM D6767.
Model: NPA-500 · Industry: Defense
Technology principle
The M19 Nanopore Analyzer (NPA-500) determines absolute and nominal pore size of coated and laminated protective fabrics and selectively permeable CBRN membranes using liquid displacement and high-pressure capillary-flow porometry. It resolves the nanoscale pore control that lets modern protective membranes block chemical and biological agents while permitting moisture-vapor escape. Referenced to ASTM F316 and ASTM D6767, the NPA-500 gives defense researchers reliable, traceable pore data for developing and qualifying next-generation protective materials.
Applications
- Selectively permeable CBRN membranes
- Coated and laminated combat fabrics
- Barrier and semipermeable membranes
- Advanced respirator media
- Protective-material R&D specimens
- Waterproof-breathable defense textiles
Key capabilities
- Lightweight, compact and ergonomically engineered, the M19 Nanopore Analyzer (NPA-500) pairs a 15" capacitive touchscreen with enhanced pressure- and flow-control hardware, so operators run a full defense test sequence with minimal training and markedly shorter cycle times. Available in aluminum or stainless-steel variants, it ships with real-time remote support, USB connectivity and remote-control automation. Domestic manufacturing in India and the USA keeps maintenance cost and downtime low, and a 2-year extended warranty is available.

Frequently asked questions
How does it outperform standard porometers?
High-pressure capillary-flow porometry reaches nanoscale pores beyond standard instrument range, essential for selectively permeable protective membranes, while remaining non-destructive.
How does high-pressure porometry improve accuracy?
The method: Applies precisely controlled high-pressure ramps Uses characterized wetting liquids Resolves closely spaced pore populations Auto-calibrates for reproducibility
What are the advantages of indigenous manufacturing?
Make-in-India build delivers supply security plus: Faster service and local support Reduced lead time and spare-parts availability Lower cost and easy customisation 2-year warranty with on-site support
Can it integrate into defense workflows?
Yes — secure records, PDF/CSV export and LIMS connectivity let nanopore data feed protective-material development and qualification.
How does it support specification compliance?
Traceability to ASTM F316 / D6767 plus tamper-proof records keeps membrane pore data audit-ready for military specification testing.
