Overview
The Spectra Invent HX-WS1845 Petroleum and Synthetic Fluid Water Separability Tester is a precision benchtop instrument engineered for the quantitative assessment of water separation behavior in lubricating oils, hydraulic fluids, turbine oils, and synthetic base stocks. It operates on the principle of gravity-driven phase separation under controlled thermal conditions, following standardized test methodologies including ASTM D1401 (Standard Test Method for Water Separability of Petroleum Oils and Synthetic Fluids) and ISO 6614 (Petroleum Products — Determination of Water Separability of Lubricating Oils). The system measures the time required for emulsified water to separate from the oil phase, as well as the volume of residual emulsion and free water at defined intervals—typically 30, 60, and 120 minutes—within a calibrated glass separator cylinder maintained at a stable temperature of 54 °C ± 1 °C or 82 °C ± 1 °C, per user-selectable test protocols.
Key Features
- Integrated high-resolution color LCD touchscreen interface with intuitive Chinese/English bilingual menu navigation and context-sensitive prompts for parameter entry and test initiation.
- Precision thermostatic bath with compact cylindrical design, optimized for rapid thermal equilibration and uniform temperature distribution across the test vessel; temperature stability maintained within ±0.5 °C over extended operation.
- Microprocessor-based timing system with programmable countdown sequences, real-time clock synchronization (displaying date, hour, minute, second), and automatic event logging at pre-set intervals (e.g., 5, 15, 30, 60, 120 min).
- Corrosion-resistant stainless-steel bath housing and borosilicate glass separator cylinders conforming to ASTM D1401 dimensional specifications (100 mL capacity, 300 mm height, 25 mm internal diameter).
- Self-diagnostic firmware with error-code reporting, sensor calibration verification prompts, and audible/visual alerts for abnormal temperature drift or timer timeout conditions.
- Modular construction supporting field serviceability; all critical components—including heating element, PT100 temperature sensor, and relay control board—are replaceable without full unit disassembly.
Sample Compatibility & Compliance
The HX-WS1845 accommodates standard 40 mL oil + 40 mL distilled water test mixtures per ASTM D1401, and is validated for use with mineral-based, polyalphaolefin (PAO), polyglycol (PAG), and phosphate ester synthetic fluids. It complies with the mechanical and procedural requirements of ASTM D1401, ISO 6614, and GB/T 7305 (Chinese national standard equivalent). The instrument’s temperature control architecture meets IEC 61000-4-3 immunity standards for electromagnetic compatibility in laboratory environments. While not certified for GLP/GMP production environments out-of-the-box, its audit-ready data logging supports traceability when paired with external secure storage and timestamped report export.
Software & Data Management
The embedded firmware records test metadata—including operator ID, sample ID, start time, bath temperature setpoint, actual bath temperature history (sampled every 10 s), and visual phase separation readings at each interval—into non-volatile memory. Results are exportable via USB flash drive in CSV format for post-processing in Excel or LIMS platforms. Optional SpectraLog™ PC software (v2.1+) enables remote monitoring, multi-instrument fleet management, and automated generation of PDF test reports compliant with 21 CFR Part 11 requirements when deployed with digital signature modules and audit trail configuration.
Applications
- Quality assurance of new and in-service turbine oils in power generation facilities, where water contamination directly impacts bearing life and oxidation stability.
- R&D evaluation of demulsibility additives during formulation development of industrial lubricants and aviation hydraulic fluids.
- Condition monitoring of marine engine oils exposed to seawater ingress, assessing degradation-induced loss of water rejection capability.
- Third-party testing laboratories performing contract analysis for OEMs requiring ASTM D1401-compliant certification documentation.
- Educational use in university tribology and petrochemical engineering labs to demonstrate interfacial phenomena and surfactant effects in multiphase fluid systems.
FAQ
What standards does the HX-WS1845 support?
ASTM D1401, ISO 6614, and GB/T 7305 are fully supported through hardware configuration, temperature accuracy, and cylinder geometry compliance.
Can the instrument operate at temperatures other than 54 °C or 82 °C?
Yes—the thermostat is programmable from 30 °C to 95 °C in 0.1 °C increments, though deviation from standard test temperatures requires method validation per ISO/IEC 17025 Clause 7.2.2.
Is calibration certificate included with shipment?
A factory-issued temperature calibration certificate traceable to NIM (National Institute of Metrology, China) is provided; users must perform annual verification using a calibrated reference thermometer.
Does the system support network connectivity or LIMS integration?
Native Ethernet or Wi-Fi is not integrated; however, USB-host mode enables batch export to networked PCs, and optional SpectraLog™ software supports OPC UA and HL7 interfaces for enterprise-level LIMS integration.
What maintenance is required for long-term reliability?
Monthly cleaning of the bath chamber and cylinder holder with isopropyl alcohol; annual recalibration of the PT100 sensor and verification of timer accuracy using a traceable stopwatch.
