Overview
The LabCompanion PH/PR/PL/PS/PM/PU Series High-Low Temperature Environmental Test Chambers are engineered for precision thermal stress evaluation of materials, components, and finished products under controlled extreme temperature conditions. These chambers operate on a dual-mode thermodynamic control architecture—combining high-efficiency scroll compressors for sub-zero refrigeration and PID-regulated resistive heating elements for rapid, stable high-temperature operation. Designed in accordance with IEC 60068-2-1 (cold test), IEC 60068-2-2 (dry heat), and ISO 16750-4 (road vehicles—environmental conditions), the series supports standardized environmental qualification protocols used in electronics reliability testing, automotive component validation, aerospace material screening, and medical device stability assessment.
Key Features
- Robust stainless-steel inner chamber construction with seamless welding and electrostatic powder-coated outer housing for corrosion resistance and long-term structural integrity.
- Independent dual-circuit refrigeration system with cascade compressor staging for reliable operation down to −70 °C—eliminating single-point failure risk during extended low-temperature dwell cycles.
- Explosion-proof variants (certified to ATEX II 2G Ex db IIB T4 Gb and/or GB 3836.1–2021 Class II C, T4) feature intrinsically safe wiring, explosion-resistant observation windows, and non-sparking internal components—suitable for volatile solvent exposure or battery cell thermal abuse testing.
- High-resolution 0.1 °C digital temperature display with real-time logging capability and adjustable alarm thresholds for over-temperature, under-temperature, and sensor fault conditions.
- Insulated double-wall chamber design with polyurethane foam (≥100 mm thickness, λ ≤ 0.022 W/m·K) ensures low thermal leakage and energy-efficient operation across full temperature range.
- Standard RS485 interface supporting Modbus RTU protocol for integration into centralized lab automation systems or SCADA platforms.
Sample Compatibility & Compliance
The chamber accommodates standard test specimens up to 500 L internal volume (model-dependent), with configurable shelf configurations (stainless steel wire mesh or solid trays). Internal dimensions and airflow patterns are validated per ASTM E145–22 Annex A1 to ensure uniform thermal distribution across load zones. All models comply with GLP/GMP documentation requirements: built-in audit trail functionality logs operator ID, parameter changes, cycle start/stop timestamps, and deviation events—fully traceable for FDA 21 CFR Part 11–compliant environments when paired with LabCompanion’s optional validation package (IQ/OQ/PQ documentation, temperature mapping reports, and uncertainty budgeting per ISO/IEC 17025).
Software & Data Management
LabCompanion’s proprietary TEMPCONTROL v4.2 software enables remote monitoring, multi-segment programmable profiles (up to 99 steps), and real-time graphing of chamber temperature vs. time. Data export is supported in CSV and Excel-compatible formats; raw log files include timestamped sensor readings from primary PT100 (Class A) and redundant backup sensors. Optional Ethernet/Wi-Fi connectivity allows secure cloud-based data archiving with role-based user access control and TLS 1.2 encryption—meeting enterprise IT security policies and facilitating cross-site comparative analysis in global R&D networks.
Applications
- Electronics: Thermal cycling of PCBAs per JEDEC JESD22-A104D and solder joint fatigue simulation.
- Automotive: Component qualification per GMW3172, Ford CETP 00.00-L-467, and ISO 16750-4 thermal shock profiles.
- Batteries: Safety testing of Li-ion cells under UL 1642 and UN 38.3 thermal abuse conditions (including forced thermal runaway initiation).
- Pharmaceuticals: Accelerated stability studies per ICH Q1A(R3) guidelines using controlled temperature ramping and hold phases.
- Polymers & Composites: Glass transition (Tg) screening, cold brittleness evaluation (ISO 974), and long-term aging simulation.
FAQ
What safety certifications do explosion-proof models carry?
All explosion-proof units meet both Chinese national standard GB 3836.1–2021 and international ATEX Directive 2014/34/EU for Group II (industrial) equipment, with detailed certification reports provided upon request.
Can the chamber be validated for GxP compliance?
Yes—LabCompanion offers full IQ/OQ/PQ validation packages including temperature mapping (per ASTM E742), uncertainty analysis, and electronic record retention compliant with 21 CFR Part 11 when used with TEMPCONTROL v4.2 and approved network infrastructure.
Is remote firmware update supported?
Firmware updates are performed via secure USB media or authenticated Ethernet upload; over-the-air (OTA) updates are not enabled by default for regulatory-controlled environments but can be configured under strict change control procedures.
What maintenance intervals are recommended?
Compressor oil and filter replacement every 12 months or 2,000 operating hours (whichever occurs first); annual calibration verification of all PT100 sensors against NIST-traceable references is strongly advised.
Does the chamber support humidity control?
No—this series is strictly dry-thermal; for combined temperature/humidity testing, refer to LabCompanion’s TH Series Environmental Chambers with integrated steam humidification and desiccant drying modules.
