Type-Approved Density Meter: DMA
Anton Paar's type-approved density and concentration meters deliver legally compliant results wherever measurements must stand up to official inspection — designed for regulated industries with outstanding precision, automation, and application expertise.
Manufacturer: Anton Paar — Austria
Overview
Anton Paar’s type-approved density and concentration meters deliver legally compliant results wherever measurements need to stand up to official inspection. Designed for regulated industries, they combine decades of application expertise with outstanding precision, automation, and connectivity. From incoming goods to final quality release, you obtain traceable, auditable data in a single, highly efficient workflow – ready for legal-for-trade use and your digital laboratory.
Type-Approved Accuracy for Legal Metrology
Rely on density and concentration results that are ready for authorities, auditors, and customers. The DMA EZ series is type-approved and designed specifically for legal metrology, so your measurements achieve official calibration and verification. Combined with Anton Paar’s decades of know-how, this secures full confidence in product release decisions and simplifies compliance with national and international standards.
Combine for a Comprehensive Measurement System
Create exactly the measuring system you need today and expand it tomorrow. By combining DMA 4101 EZ, 4501 EZ, and 5001 EZ with various Anton Paar measuring modules, you determine all relevant parameters – such as density, concentration, and more – in a single measurement run. This modularity reduces sample handling, minimizes operator influence, and shortens overall analysis time, while ensuring a consistent, harmonized workflow across different products, methods, and laboratory locations.
Automation and Digital Connectivity
Boost throughput and reduce manual steps with automated sample changers that handle filling, cleaning, and measurement sequences. This improves safety and frees your team to focus on higher-value tasks. Direct integration into the AP Connect lab execution system brings all results into one digital platform, enabling paperless documentation, easy tracking of legal-for-trade measurements, and seamless data transfer to LIMS or ERP systems for end-to-end compliance.
U-View and FillingCheck: Error-Free Measurements
See what’s happening inside the measuring cell – in real time. U-View provides a zoomable live image so operators can visually verify every filling, while FillingCheck automatically detects microbubbles or improper filling conditions. Together they significantly reduce measurement errors and rework, enabling secure, traceable results even with challenging or opaque samples, and giving operators immediate feedback that supports robust, standardized routines.
