Shenkai SYP1003-IXA Kinematic Viscosity Tester

Overview

The Shenkai SYP1003-IXA Kinematic Viscosity Tester is a precision-engineered instrument designed for the accurate determination of kinematic viscosity in Newtonian liquid petroleum products—such as lubricating oils, base oils, diesel fuels, and transformer oils—according to internationally harmonized standard test methods. It operates on the capillary efflux principle defined in ASTM D445, ISO 3104, and GB/T 265, where kinematic viscosity (ν, in mm²/s or cSt) is calculated as the product of the capillary constant (C) and the efflux time (t), i.e., ν = C × t. The instrument integrates a high-stability, digitally controlled constant-temperature bath with dual-wall hard-glass construction to ensure minimal thermal gradient, rapid equilibration, and long-term temperature uniformity across all four test positions. Its architecture supports both routine QC testing in refinery laboratories and method validation under GLP-compliant workflows.

Key Features

• High-precision digital temperature control system with ±0.01 °C stability over the full operating range (ambient to 100 °C); optional immersion chiller enables stable operation at 20 °C
• Double-walled borosilicate glass bath (Ø300 mm × 300 mm) with optimized thermal mass and low thermal inertia for rapid stabilization and reduced energy consumption
• Four independent test ports accommodating standard Ubbelohde or Cannon-Fenske capillaries; each position features precise vertical alignment capability via optional external micrometer-adjustable holder (360° rotational adjustment)
• Integrated LED illumination system ensures clear visual inspection of meniscus movement during efflux timing—critical for operator consistency and ASTM D445 manual timing compliance
• Over-temperature safety cutoff with automatic power disconnection prevents thermal runaway and protects both personnel and capillary viscometers
• Modular mechanical design allows tool-free removal of stirring assembly, heating elements, and temperature sensor—facilitating preventive maintenance and calibration traceability
• Low-noise, high-torque 40 W stirring motor driving a 50 mm-diameter impeller at 1250 rpm to maintain homogeneous bath temperature distribution per ISO 3104 Annex A requirements

Sample Compatibility & Compliance

The SYP1003-IXA is validated for use with transparent, Newtonian liquids having kinematic viscosities ranging from approximately 0.2 to 100,000 mm²/s (cSt), depending on selected capillary dimensions and test temperature. It accommodates all capillaries certified to SH/T 0173 (Chinese national standard aligned with ISO 3105), including those calibrated for ASTM D445 Grade I and II accuracy classes. The instrument’s thermal performance meets the bath uniformity and stability criteria specified in ASTM D445 Section 7.2 and ISO 3104 Clause 6. All electronic controls—including temperature setpoint logging, run-time stamping, and alarm event records—support audit-ready documentation for laboratories operating under ISO/IEC 17025, API RP 2550, or internal GMP quality systems.

Software & Data Management

While the base configuration operates via standalone digital controller with front-panel keypad and real-time LCD display, the SYP1003-IXA supports optional RS-485 or USB interface modules for integration into LIMS or ELN environments. When paired with Shenkai’s optional ViscCalc Pro software (v3.2+), users can import capillary calibration certificates, auto-calculate kinematic viscosity using ASTM D445 correction algorithms (e.g., for kinetic energy correction and meniscus correction), generate PDF test reports compliant with 21 CFR Part 11 requirements (including electronic signatures, audit trails, and user-access logs), and export raw efflux times with timestamped metadata for statistical process control (SPC) analysis.

Applications

• Refinery QC labs: Routine monitoring of crude distillate fractions, finished lubricants, and fuel blending components
• Independent testing laboratories: Third-party certification of viscosity grade compliance per SAE J300, API 1509, or ISO 3448
• R&D departments: Screening of synthetic base stocks, additive packages, and bio-derived fuels under variable temperature profiles
• Regulatory compliance units: Supporting ASTM D445-based submissions for EPA, CE marking, or China NMPA registration dossiers
• Calibration service providers: Serving as a reference bath for verifying capillary viscometer constants per ISO 3105

FAQ

What standards does the SYP1003-IXA comply with for kinematic viscosity measurement?

It is fully compliant with ASTM D445, ISO 3104, and GB/T 265 for methodology, and its thermal performance satisfies the bath uniformity and stability requirements outlined in Annex A of ISO 3104 and Section 7 of ASTM D445.
Can the instrument be used for non-petroleum Newtonian fluids such as glycerol or silicone oils?

Yes—provided the fluid is optically clear, non-volatile at test temperature, and exhibits Newtonian flow behavior within the selected capillary’s shear rate range. Users must verify capillary selection and efflux time limits per ASTM D445 Section 6.
Is the temperature display traceable to national standards?

The integrated Pt100 sensor is factory-calibrated against NIST-traceable references; optional on-site calibration certificate (ISO/IEC 17025 accredited) is available upon request.
Does the unit support automated timing integration with external stopwatches or vision-based systems?

Yes—via TTL-level trigger input/output ports (optional module), enabling synchronization with high-speed cameras or programmable logic controllers for unattended efflux detection.
What maintenance intervals are recommended for long-term accuracy?

Stirring impeller cleaning and bath fluid replacement every 6 months; annual verification of temperature sensor linearity and capillary alignment using Shenkai’s Calibration Kit CK-SYP1003.
