Yuelian YT1-126-40T-3S Triple-Station Environmental Tensile Tester with Integrated -40°C to +150°C Climate Chamber

Overview

The Yuelian YT1-126-40T-3S is a triple-station environmental tensile testing system engineered for high-reproducibility mechanical characterization of polymeric, metallic, elastomeric, and composite materials under controlled thermal and hygrometric conditions. Unlike conventional single-axis testers, this platform integrates three fully independent test stations within a shared climate-controlled chamber—enabling simultaneous, synchronized evaluation of identical or heterogeneous specimens across identical or differential temperature/humidity profiles. The system operates on the principle of servo-motor-driven uniaxial force application, coupled with precision ball-screw transmission and optical encoder-based displacement feedback. Its core architecture supports standardized tensile, compression, peel (90° and 180°), tear, shear, and unwind force measurements per ISO 527, ASTM D882, ASTM D3330, ISO 8510-2, and GB/T 2792. The integrated climate chamber employs PID-controlled refrigeration (eco-friendly R134a or R404A compressor), SUS304 stainless steel heating elements, and forced-air circulation—delivering stable thermal environments from –40°C to +150°C with ±1°C uniformity and 20–98% RH control.

Key Features

• Triple independent test stations (3 × 100 kg capacity), each with dedicated load cell, displacement sensor, and real-time data acquisition channel
• Modular climate chamber: removable for ambient-temperature testing—maximizing lab flexibility and workspace utilization
• High-fidelity force measurement: 24-bit isolated ADC, continuous-range signal conditioning (no range switching), 0.5% full-scale accuracy per ASTM E4, 1/1,000,000 resolution
• Sub-micron displacement resolution via dual-mode electronic extensometry (optional) and encoder feedback, supporting both macro- and micro-strain analysis
• Low-noise mechanical drive: servo motor + preloaded ball screw + timing belt transmission, achieving acoustic emissions <65 dB(A) at 100 mm/min
• Hardware-level safety redundancy: dual mechanical end-limit switches, emergency stop circuit with hardware interlock, automatic over-travel and overload shutdown
• SUS304 stainless steel chamber interior and structural frame—corrosion-resistant, non-outgassing, compliant with cleanroom-grade material handling protocols

Sample Compatibility & Compliance

The YT1-126-40T-3S accommodates specimens up to 600 mm in length and 350 mm in width within its climate chamber, supporting standard dumbbell, strip, film, foil, adhesive tape, gasket, and flexible packaging geometries. Fixture kits include three sets of 180° peel jaws, one set of 90° peel fixtures, extension rods for elevated grip separation, and active cooling modules to mitigate localized thermal drift during prolonged high-temperature tests. All mechanical and software subsystems are designed to meet GLP and GMP documentation requirements: full audit trail logging (user actions, parameter changes, calibration events), electronic signature support, and 21 CFR Part 11–compliant data integrity architecture. System validation documentation—including IQ/OQ protocols aligned with ISO/IEC 17025 and ASTM E2586—is available upon request.

Software & Data Management

The 2020-generation Yuelian TestMaster Pro software provides a unified interface for concurrent multi-station control, real-time curve overlay, and comparative statistical analysis. It natively supports EN, CN, and JP language interfaces—with automatic bidirectional translation of metadata, report headers, and database entries. Unit management includes SI, imperial, and legacy systems (e.g., kgf/cm², lbf/in), with seamless in-session conversion. Over 169 standardized stress–strain models (including Mooney-Rivlin, Ogden, and hyperelastic formulations) are embedded for post-test constitutive fitting. Reports are generated via Crystal Reports Engine and exportable to PDF, DOCX, and XLSX formats—with configurable templates, user-defined logos, and automated compliance stamping. All raw data reside in encrypted Microsoft Access databases; VBS-scriptable calculation modules enable custom modulus derivation, creep compliance interpolation, and hysteresis loop quantification—facilitating method transfer and internal SOP development.

Applications

• Temperature-dependent modulus mapping of thermoplastics (e.g., PP, PET, PC) across glass transition regimes
• Adhesive peel strength benchmarking under automotive under-hood thermal cycling (-40°C → +125°C)
• Medical device polymer validation per ISO 10993-12 (cytotoxicity-adjacent mechanical stability)
• Flexible electronics substrate tensile reliability assessment at elevated humidity (85% RH / 85°C)
• Quality control of lithium-ion battery separator films under dry and humidified conditions
• Comparative aging studies: pre-conditioned vs. as-received specimens subjected to identical strain-rate protocols
• Regulatory submission support for FDA 510(k), CE-MDR, and NMPA Class III device dossiers

FAQ

Can the climate chamber be operated independently of the mechanical testing stations?
Yes—the chamber is mechanically decoupled and may run standalone temperature/humidity profiles for pre-conditioning or storage, without engaging the drive system.
Is third-party calibration certification included with shipment?
Factory calibration per ISO/IEC 17025 is provided; accredited external calibration (e.g., by A2LA or UKAS labs) is available as an optional service.
Does the system support dynamic mechanical analysis (DMA) modes?
No—this is a quasi-static tensile/compression platform. For oscillatory testing, refer to Yuelian’s DMA-500 series.
What is the maximum allowable specimen thickness inside the chamber?
The usable vertical clearance between grips is 620 mm; total specimen height—including fixtures—must remain ≤580 mm to ensure unobstructed thermal airflow.
Are firmware updates and software patches provided post-purchase?
Yes—Yuelian offers free lifetime minor-version updates and paid major-version upgrades, with version-controlled release notes and backward-compatible data migration tools.
