Anton Paar Portable Density Meter: DMA 35 Ex

Anton Paar DMA 35 Ex: The Ultimate Portable Density Meter for Any Environment

Overview: Unmatched Precision in a Field-Ready Device

The Anton Paar DMA 35 Ex is a state-of-the-art portable density meter engineered for fast, accurate, and reliable measurements in even the most demanding environments. It masterfully bridges the gap between laboratory-grade precision and field-ready durability, making it an indispensable tool across a wide range of industries, including chemicals, petroleum, food and beverage, and battery production. Built with advanced technologies like air cushion shock absorption, smart oscillator placement, and intrinsic safety, the DMA 35 Ex ensures seamless, safe, and accurate operation wherever your work takes you.

Key Features: A Closer Look

1. Exceptional Accuracy in All Conditions The DMA 35 Ex delivers density and concentration measurements with lab-level precision (± 0.001 g/cm³), regardless of external conditions. Whether you're working outdoors, on a factory floor, or in a rugged industrial setting, you can trust its results.

2. Robust, Durable, and Portable Design Engineered for the real world, its splash-proof (IP54) and leak-proof housing is reinforced with additional rubber protection. This design makes the DMA 35 Ex ideal for on-site measurements, providing outstanding durability and safety against drops, shocks, and spills.

3. Intrinsic Safety for Hazardous Areas The "Ex" designation signifies its intrinsic safety, compliant with ATEX and IECEx standards for use in explosive atmospheres (Zone 2). This makes it the only portable density meter on the market designed for safely measuring flammable chemicals like fuels, solvents, and alcohols. The DMA 35 Ex Petrol model is specifically optimized for the petroleum industry.

4. Advanced Measurement Technology

• Bubble-Free Results: Integrated air cushion technology actively prevents air bubbles from interfering with the U-tube oscillating sensor, ensuring consistently accurate readings.
• High-Temperature Capability: Measure sample temperatures up to 100 °C, enabling real-time process decisions, such as monitoring hot wort in brewing.
• Automatic Viscosity Correction: An intelligent algorithm automatically compensates for high sample viscosity, delivering reliable results even with thick liquids.

Designed for the User: Intuitive and Efficient Operation

• Glove-Friendly Interface: The device features responsive capacitive keys that can be operated easily, even while wearing protective gloves.
• Ambidextrous Design: Symmetrical construction ensures comfortable use for both left- and right-handed operators.
• One-Handed Gesture Control: A smart gesture control system allows for one-handed operation, perfect for taking samples from hard-to-reach locations.
• Auto-Rotating Display: The bright, backlit display automatically rotates its orientation, ensuring perfect visibility of results no matter how you hold the instrument.

Data Handling and Full Traceability

The DMA 35 Ex simplifies data management and reporting, ensuring full traceability in compliance with GMP/GLP standards.

• Onboard Memory: Store up to 1,200 measurement results, 30 distinct measuring methods, and 250 unique sample IDs directly on the device.
• Wireless Data Exchange: Utilize Bluetooth® or RFID (read & write) for seamless, cable-free data transfer to a PC, printer, or other devices.
• Effortless Reporting: Export results to your computer or a Bluetooth® printer without needing any additional software, streamlining the documentation process.
