What does the DP-500 measure for water membranes?
It quantifies diffusion and selectivity: Gas / small-molecule transmission rate Permeance and permeability Selectivity between species Diffusion behavior over time
EXPERIENCE THE most advanced Diffusional Permeability Analyzer
M19 Diffusional Permeability Analyzer (DP-500) for water purification — AI-based, ultra-high-precision testing. Standards: ISO 15105-1, ASTM D1434.
Model: DP-500 · Industry: Water Purification
Technology principle
The M19 Diffusional Permeability Analyzer (DP-500) measures the diffusion of gases and small molecules through water-treatment membranes, characterizing selectivity and barrier behavior that influence membrane fouling, degassing and separation performance. Referenced to ISO 15105-1 and ASTM D1434, the DP-500 gives membrane researchers reliable diffusion and selectivity data to develop and qualify advanced separation membranes.
Applications
- Membrane degassing / contactors
- Forward-osmosis membranes
- Thin-film composite membranes
- Barrier and separation membranes
- Hollow-fiber membranes
- Specialty separation media
Key capabilities
- Lightweight, compact and ergonomically engineered, the M19 Diffusional Permeability Analyzer (DP-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.
