What does the NPA-500 measure for water membranes?
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 water purification — AI-based, ultra-high-precision testing. Standards: ASTM F316.
Model: NPA-500 · Industry: Water Purification
Technology principle
The M19 Nanopore Analyzer (NPA-500) determines absolute and nominal pore size of reverse-osmosis, nanofiltration and ultrafiltration membranes using liquid displacement and high-pressure capillary-flow porometry. Nanoscale pore control governs the removal of heavy metals, pesticides, salts and fine contaminants from water. Referenced to ASTM F316, the NPA-500 gives membrane developers the fine-resolution pore data needed to engineer and qualify high-rejection water-treatment membranes.
Applications
- Reverse-osmosis (RO) membranes
- Nanofiltration (NF) membranes
- Ultrafiltration (UF) membranes
- Hollow-fiber membranes
- Thin-film composite membranes
- Desalination membranes
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 water purification 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 range, essential for NF/UF 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 domestic manufacturing?
Local build delivers: Faster service and local support Reduced lead time and spare-parts availability Lower import cost and easy customisation 2-year warranty with on-site support
Can it integrate into water-treatment workflows?
Yes — secure records, connectivity and PDF/CSV export let nanopore data feed membrane development and qualification.
How does it support standards compliance?
Traceability to ASTM F316 plus tamper-proof records keeps membrane pore data audit-ready for QA.
