Overview
The Schmidt + Haensch EDM 5000 is a high-precision, fully automated digital density meter engineered for continuous, real-time density determination of liquids and low-viscosity solutions. Based on the oscillating U-tube principle (DIN EN ISO 12185, ASTM D4052), the instrument measures the resonant frequency of a precisely manufactured borosilicate glass U-tube filled with sample—directly correlating to mass per unit volume. Its robust, hermetically sealed design ensures long-term stability and operational reliability in demanding industrial and quality control environments. Manufactured in Germany in 2015 and maintained under controlled storage conditions, this unit has undergone only limited demonstration use (99% functional and cosmetic integrity. It represents a cost-optimized entry point into S+H’s legacy of metrological excellence—without compromise on traceability, repeatability, or compliance readiness.
Key Features
- Integrated oscillating U-tube sensor with temperature-controlled Peltier element (±0.01 °C stability over full 15–40 °C operating range)
- Automatic bubble detection and rejection algorithm, preventing erroneous readings due to entrapped air or incomplete filling
- High-resolution 7-inch color TFT touchscreen interface with intuitive icon-driven navigation and multilingual OS support (English, German, French, Spanish)
- Onboard reference calibration using certified standard fluids (e.g., air/water at 20 °C), supporting dual-point verification prior to critical measurements
- Stainless-steel fluidic path and chemically resistant wetted materials (FEP, PTFE, borosilicate glass) compatible with hydrocarbons, alcohols, aqueous electrolytes, and food-grade formulations
- Self-diagnostics suite including tube resonance amplitude monitoring, temperature gradient validation, and sensor drift alerting
Sample Compatibility & Compliance
The EDM 5000 accommodates liquid samples with dynamic viscosity up to 20 mPa·s and density range from 0.6 to 3.1 g/cm³. It supports manual syringe loading or optional integration with autosamplers (e.g., Gerstel MPS). The system meets fundamental requirements of ISO/IEC 17025:2017 for testing laboratories and aligns with method validation frameworks outlined in USP , EP 2.2.5, and ASTM D1298. While not pre-certified for FDA 21 CFR Part 11, its audit trail functionality—including timestamped measurement logs, operator ID fields, and immutable raw frequency data export—enables straightforward configuration for GLP/GMP environments upon site-specific validation.
Software & Data Management
Instrument control and data handling are managed via S+H’s native WinDensity software (v3.8.x, included), installed on an external Windows PC (not supplied). The software enables method parameterization (temperature setpoint, equilibration delay, averaging iterations), real-time trend visualization, statistical reporting (mean, SD, RSD, min/max), and CSV/PDF export compliant with LIMS ingestion protocols. All measurement records include embedded metadata: ambient temperature/humidity, operator ID, calibration status, and raw oscillation period values—ensuring full traceability. Audit trail entries are write-protected and cannot be edited or deleted post-acquisition.
Applications
- Petroleum refining: API gravity, distillate density grading, blending optimization
- Chemical manufacturing: Concentration verification of H₂SO₄, NaOH, HNO₃, and organic solvents
- Food & beverage: Brix correction, alcohol content estimation (via density-alcohol tables), syrup consistency control
- Pharmaceutical excipients: Density screening of glycerol, propylene glycol, and PEG solutions
- Academic research: Thermophysical property studies requiring high-reproducibility density vs. temperature profiling
FAQ
Is this unit covered by original factory warranty?
No—the original S+H manufacturer warranty expired in 2017. However, this unit includes a six-month comprehensive on-site service agreement covering labor, travel, and parts (excluding consumables), administered by our authorized technical support team.
Can the EDM 5000 be integrated into an existing LIMS or SCADA system?
Yes—via RS-232 or optional Ethernet interface, using ASCII-based command protocol documented in the OEM Communication Manual. Custom OPC UA or Modbus TCP gateways can be deployed externally.
What documentation accompanies the instrument?
Factory calibration certificate (2015), user manual (English), WinDensity software license key, USB cable, cleaning kit, and blank QC logbook. No original packaging or shipping crates are included.
Does the unit require annual recalibration?
Per ISO/IEC 17025 and internal QA policies, we recommend annual verification against NIST-traceable standards; full recalibration is required if drift exceeds ±0.0002 g/cm³ across the working range.
Is installation and commissioning support provided?
Remote setup assistance is included. On-site installation, level verification, and first-run qualification testing are available as a billable service (quoted separately).
