METTLER TOLEDO Density2Go Portable Handheld Densimeter

Overview

The METTLER TOLEDO Density2Go is a high-precision portable handheld densimeter engineered for rapid, field-deployable density and concentration measurements across laboratory, production, and on-site environments. It operates on the principle of oscillating U-tube densimetry — a well-established, ISO 12185-compliant method that determines density by measuring the resonant frequency of a filled sample tube under controlled temperature conditions. The instrument’s microprocessor-controlled oscillator delivers stable, repeatable frequency readings, which are converted into density values using factory-calibrated algorithms traceable to NIST-certified standards. With a measurement range from 0.000 to 3.000 g/cm³ and accuracy of ±0.001 g/cm³, the Density2Go meets the metrological requirements of quality control in pharmaceuticals, food & beverage, petrochemicals, chemical manufacturing, and brewing industries. Its compact, ergonomic design enables single-hand operation without external power sources during routine use — ideal for mobile QA/QC personnel performing in-line checks or raw material verification at receiving docks.

Key Features

• Oscillating U-tube technology ensures high reproducibility (±0.0005 g/cm³) and minimal operator dependency.
• Integrated Peltier-controlled temperature regulation maintains sample temperature stability within ±0.02 °C across the 0–50 °C operating range.
• Bright, sunlight-readable color LCD with adjustable backlight enhances usability in both indoor laboratories and outdoor industrial settings.
• Intuitive guided workflow mode (Densito) walks users step-by-step through sample loading, measurement, cleaning, and result confirmation — reducing training time and minimizing procedural errors.
• DensitoPro variant adds Bluetooth 5.0 connectivity, integrated RFID/barcode reader for sample ID auto-capture, and extended ambient operating range (0–50 °C).
• Robust IP54-rated housing provides resistance against dust ingress and incidental water splashes — suitable for non-sterile industrial environments.

Sample Compatibility & Compliance

The Density2Go accommodates a wide variety of liquid and low-viscosity semi-liquid samples, including aqueous solutions, hydrocarbons, alcohols, acids (e.g., sulfuric acid up to 98%), syrups, and ethanol-water mixtures. Sample volume requirement is only 1–2 mL per measurement. Temperature compensation is applied automatically using built-in reference tables compliant with ASTM D1298 (petroleum), ISO 2719 (fuels), and OIML R 22 (alcoholic beverages). All measurement data include timestamps, instrument ID, operator ID (via optional login), sample ID, temperature correction factor, and selected unit — fulfilling documentation requirements under FDA 21 CFR Part 11 when used with validated EasyDirect PC software and electronic signature protocols. Instrument firmware supports audit trail generation and secure data export in CSV or PDF formats compatible with LIMS integration.

Software & Data Management

EasyDirect PC software serves as the central hub for instrument configuration, method management, report generation, and long-term data archiving. It supports customizable report templates aligned with internal SOPs or regulatory submission formats (e.g., ICH M4, USP ). Each stored result (up to 1,100 entries on-device) includes metadata such as date/time stamp, temperature, unit selection, and user-defined notes. DensitoPro enables wireless synchronization via Bluetooth, allowing real-time data transfer to networked workstations or cloud-based QA platforms. Data encryption during transmission and local storage complies with ISO/IEC 27001 information security benchmarks. Firmware updates are delivered through signed packages verified via SHA-256 hash integrity checks.

Applications

• Pharmaceutical: Excipient density verification, solvent purity assessment, and formulation consistency checks per USP .
• Food & Beverage: Brix determination in fruit juices, sugar syrup concentration, alcohol content in wines and spirits (US/UK proof), and Plato in wort analysis.
• Petrochemical: API gravity and sulfuric acid concentration monitoring in refining and blending operations.
• Chemical Manufacturing: Quality release testing of solvents, catalyst slurries, and electrolyte solutions.
• Academic Research: Teaching labs utilizing density as a fundamental physical property in thermodynamics and solution chemistry experiments.

FAQ

What temperature calibration standards are supported?
The instrument supports user-defined temperature calibration using certified reference liquids (e.g., water, air, sodium chloride solutions) traceable to national metrology institutes.
Can the Density2Go be calibrated in-house?
Yes — two-point calibration with air and water (or other certified standards) is fully supported via the onboard calibration wizard.
Is the device compliant with ISO/IEC 17025 requirements?
When operated within documented procedures and maintained according to METTLER TOLEDO’s service schedule, it supports ISO/IEC 17025 clause 6.4 (equipment) and 6.5 (traceability) requirements.
How is data integrity ensured during export?
All exported files contain embedded digital signatures, checksums, and full metadata — enabling verification of origin, completeness, and immutability in regulated environments.
Does the instrument support custom concentration curves?
Yes — up to five user-defined concentration-density correlation curves can be programmed and recalled per method.
