Overview
The LabCompanion PS-408 High-Low Temperature Environmental Test Chamber is an engineered solution for precise thermal stress evaluation across industrial quality control, materials science research, and product reliability validation. Designed in accordance with fundamental thermodynamic control principles, the chamber employs dual-stage compressor-based refrigeration combined with PID-controlled resistive heating to achieve stable, repeatable temperature profiles within a wide operational envelope of –70 °C to +150 °C. Its robust stainless-steel inner chamber and high-efficiency insulation minimize thermal leakage and support long-duration testing under static or dynamic thermal cycling conditions. The system is optimized for applications requiring compliance with international environmental test standards including IEC 60068-2-1 (cold), IEC 60068-2-2 (dry heat), and MIL-STD-810G Method 502.6.
Key Features
- Wide temperature range: –70 °C to +150 °C, validated per IEC 60068-3-5 ambient conditioning protocols
- PID-controlled heating and multi-stage vapor-compression cooling ensure minimal overshoot and high thermal stability
- Temperature fluctuation ≤ ±0.5 °C (measured at chamber center, steady-state condition)
- Temperature uniformity and deviation maintained within ±2.0 °C across the full working volume
- Programmable ramp rates: heating up to 3.0 °C/min and cooling at 1.2 °C/min — configurable via embedded controller
- Stainless-steel interior (SUS304) with seamless welding, corrosion-resistant exterior housing, and double-glazed observation window
- Integrated safety interlocks: over-temperature cutoff, compressor high-pressure protection, and door-open alarm
- Standard RS485 interface for remote monitoring; optional Ethernet/Modbus TCP upgrade available for factory automation integration
Sample Compatibility & Compliance
The PS-408 accommodates samples up to 800 mm (W) × 850 mm (D) × 600 mm (H), supporting electronics assemblies, automotive components, polymer specimens, PCBs, battery modules, and packaging materials. Its internal geometry permits unobstructed airflow distribution via axial fans and baffle-guided circulation, ensuring representative thermal exposure per ASTM E145 and ISO 16750-4 requirements. The chamber meets CE marking criteria for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). While configured as a standard (non-explosion-proof) unit, it may be deployed in Class 1, Division 2 environments when installed per NEC Article 500 guidelines and paired with external hazardous-area-rated instrumentation.
Software & Data Management
The PS-408 includes an embedded 7-inch color touchscreen controller with intuitive menu navigation and real-time graphical display of setpoint, actual temperature, and ramp status. Up to 100 programmable test profiles — each supporting up to 99 segments (ramp/soak/hold) — can be stored locally. Data logging records temperature at user-defined intervals (1 s to 60 min) with timestamping and automatic CSV export via USB. Optional LabCompanion TCMS v4.2 software enables PC-based test sequencing, multi-chamber synchronization, audit trail generation, and 21 CFR Part 11-compliant electronic signatures when deployed in GLP/GMP-regulated laboratories. All logged data include metadata such as operator ID, calibration status, and environmental sensor IDs to satisfy traceability requirements.
Applications
- Thermal cycling validation of lithium-ion battery cells and modules per UN 38.3 Section 42.3
- Pre-conditioning of aerospace composites prior to mechanical testing (ASTM D5083)
- Accelerated aging studies of elastomers and sealants under extreme low-temperature embrittlement conditions
- Qualification testing of automotive ECUs per ISO 16750-4 and GMW3172
- Reliability screening of consumer electronics per JEDEC JESD22-A104E
- Stability assessment of pharmaceutical packaging under ICH Q1A(R2) climatic zone IV conditions
- Calibration reference environment for temperature-sensitive metrology equipment
FAQ
What is the maximum sample weight the PS-408 can accommodate without compromising thermal performance?
The chamber is rated for continuous operation with total internal mass ≤ 50 kg. Exceeding this load may extend stabilization time and marginally affect uniformity; load-specific validation is recommended for critical applications.
Does the PS-408 support humidity control?
No — the PS-408 is a dry-temperature-only chamber. For combined temperature/humidity testing, consider the LabCompanion PH series (e.g., PH-600-40) with integrated steam humidification and dehumidification systems.
Is third-party calibration certification included with delivery?
A factory-as-built temperature mapping report (per ISO/IEC 17025-accredited procedure) is provided. NIST-traceable calibration certificates are available as an optional add-on with documented uncertainty budgets.
Can the controller be integrated into a central SCADA or MES platform?
Yes — native Modbus RTU (RS485) is standard; optional Ethernet gateway firmware enables MQTT/OPC UA connectivity for Industry 4.0 infrastructure interoperability.
What maintenance intervals are recommended for optimal long-term repeatability?
Compressor oil and refrigerant levels should be verified annually; condenser coils require cleaning every 6 months in non-cleanroom environments. Full preventive maintenance, including sensor recalibration and PID tuning verification, is advised every 24 months.
