Manufacturer: Anton Paar — Austria
Overview
Inspired by over 55 years of expertise in benchtop density measurement, the DMA 4002, DMA 5002, and DMA 6002 modular benchtop density meters combine automated functions with unmatched precision and reliability. As the fastest, most modular benchtop density meters in Anton Paar's portfolio, they deliver four-digit results in just 20 seconds – powered by U-Pulse technology based on the patented Pulsed Excitation Method for best-in-class accuracy.
The instruments offer storage of up to 10,000 measurements and deliver accuracy up to six digits. Daily operations are simplified with features such as U-Dry, one-touch measurement, and a measurement status light, while compliance with a wide range of standards ensures peace of mind.
Outstanding Features that Simplify Workflows
- One-touch measurement: Measurement at the push of a button
- U-Dry: Effortless hand-swipe measurement drying
- FillingCheck: Detection of microbubbles in seconds
- U-View: Zoomable image of the measuring cell
- ThermoBalance: Automatic compensation of temperature effects
- Guided user workflows for simplified operation
Unmatched Precision, Powered by U-Pulse Technology
U-Pulse, based on Anton Paar's patented Pulsed Excitation Method, delivers best-in-class performance – with outstanding precision, repeatability, and reproducibility, whether in high-precision R&D or routine quality control.
Multiparameter Measurement Systems
The DMA 4002, DMA 5002, and DMA 6002 modular benchtop density meters can be connected to a variety of Anton Paar measuring modules, enabling users to capture all key quality control parameters from a single sample – under identical conditions.
Automation that Drives Productivity
Fully automated filling, measuring, and cleaning processes take throughput to the next level. Every Anton Paar benchtop density meter is compatible with a wide range of sample changers, enabling tailored setups for maximum speed and reliability. The instruments ensure accurate, operator-independent results while protecting users by minimizing contact with hazardous substances – all while keeping workflows in motion.
Compliance with Key Standards
The DMA 4002, DMA 5002, and DMA 6002 modular benchtop density meters ensure full compliance with ASTM D4052, D5002, D1250, and ISO 12185 for petroleum testing, as well as all relevant pharmacopeias. They also support data integrity and traceability in line with regulations such as 21 CFR Part 11.
Models
All three models offer one-touch measurement at the push of a button, U-Dry effortless hand-swipe drying, a syringe and measurement status light, combinability with 30+ modules for a measurement system, and automated filling and rinsing via the Xsample series sample changers.
