Overview
The LabCompanion PU-408 is a precision-engineered environmental test chamber designed for accelerated thermal aging, high/low temperature cycling, and long-term stability evaluation of materials, components, and finished products. It operates on a forced-air convection principle with dual-stage refrigeration and PID-controlled electric heating, enabling stable and repeatable thermal profiles across its full operating range of −40 °C to +150 °C. Unlike humidity-capable variants (e.g., PL or PSL series), the PU-408 is a dry-thermal-only chamber—optimized for applications where moisture control is neither required nor desirable, such as polymer degradation studies, electronic component burn-in, rubber vulcanization validation, and metallurgical phase stability testing. Its robust stainless-steel interior, insulated double-wall construction, and calibrated sensor array ensure compliance with core thermal testing requirements defined in ASTM D3045, ISO 2812-3, IEC 60068-2-1 (cold), IEC 60068-2-2 (dry heat), and MIL-STD-810H Method 502.6.
Key Features
- Wide operational temperature span: −40 °C to +150 °C, supporting both low-temperature embrittlement and high-temperature oxidation assessments
- High thermal stability: ±0.5 °C temperature fluctuation and ≤2.0 °C uniformity across the working volume, verified per IEC 60068-3-5
- Precision PID temperature controller with real-time digital display, programmable ramp-soak profiles, and auto-tuning capability
- Forced-air circulation system with adjustable multi-directional airflow vanes to minimize thermal stratification
- Double-layer insulated chamber walls with high-density polyurethane foam (≥100 mm thickness) and stainless-steel 304 interior lining
- Over-temperature, over-current, and compressor high-pressure protection circuits compliant with IEC 61000-6-2 EMC standards
- Standard RS-485 interface supporting Modbus RTU protocol for integration into centralized lab monitoring systems
Sample Compatibility & Compliance
The PU-408 accommodates samples up to 600 mm (W) × 850 mm (H) × 800 mm (D), with load capacity optimized for industrial-grade PCB assemblies, automotive gaskets, aerospace sealants, and bulk polymer specimens. Its dry-thermal architecture eliminates condensation-related artifacts—critical for evaluating thermo-oxidative degradation kinetics in thermoplastics (e.g., PP, ABS, PC) and elastomers (e.g., EPDM, silicone). The chamber meets essential safety and performance benchmarks including CE marking (2014/30/EU EMC Directive, 2014/35/EU LVD Directive), RoHS 2011/65/EU, and conforms to GLP-relevant instrument qualification protocols (IQ/OQ/PQ documentation support available upon request). While not humidity-equipped, its thermal performance data is traceable to NIST-traceable reference thermometers and validated per ISO/IEC 17025-accredited calibration procedures.
Software & Data Management
The integrated controller supports up to 100 programmable test segments with user-defined ramp rates, dwell times, and cycle counts. Optional LabCompanion TC-Link software (Windows-based) enables remote monitoring, real-time graphing, automated report generation (PDF/CSV), and audit-trail logging aligned with FDA 21 CFR Part 11 requirements—including electronic signatures, user access levels, and immutable data archiving. All temperature readings are timestamped with millisecond resolution and stored internally for ≥30 days; external USB export is supported without firmware modification. Data integrity is preserved via cyclic redundancy check (CRC) verification during transfer and EEPROM-backed memory retention during power interruption.
Applications
- Accelerated life testing of electronic encapsulants and conformal coatings under thermal stress
- Evaluation of thermal expansion mismatch in multilayer ceramic capacitors (MLCCs) and BGA packages
- Validation of shelf-life predictions for pharmaceutical excipients and medical device polymers per ICH Q1A(R2)
- Qualification of adhesive bond strength retention after prolonged exposure to elevated temperatures
- Material screening for automotive under-hood components per SAE J2334 and GMW15001
- Pre-conditioning of sensors and MEMS devices prior to functional testing
FAQ
Is the PU-408 suitable for humidity-controlled testing?
No. The PU-408 is a dry-thermal-only chamber. For combined temperature/humidity testing, consider the PL-408 or PSL-408 series.
Does it support custom calibration certificates?
Yes—NIST-traceable calibration reports (including as-found/as-left data at three points: −40 °C, 25 °C, +150 °C) are available as an optional service.
What is the maximum sample mass the chamber can stabilize?
While no fixed mass limit is specified, thermal load capacity is governed by heat capacity and surface-area-to-volume ratio; typical stabilization time increases by ≤15% for loads up to 50 kg of aluminum equivalent.
Can it be integrated into a SCADA or MES environment?
Yes—via standard Modbus RTU over RS-485; OPC UA gateway compatibility is achievable through third-party middleware.
Is maintenance training provided with purchase?
LabCompanion offers on-site or virtual commissioning support, including preventive maintenance protocols, sensor verification routines, and controller firmware update guidance.
