LabCompanion PG-80 Compact High-Low Temperature Environmental Test Chamber

Overview

The LabCompanion PG-80 Compact High-Low Temperature Environmental Test Chamber is an engineered solution for precise thermal stress evaluation of materials, components, and electronic assemblies under controlled extreme temperature conditions. Designed in accordance with fundamental thermodynamic principles and validated thermal chamber architecture, the PG-80 employs a dual-stage cascade refrigeration system combined with PID-controlled electric heating to achieve stable operation across a wide temperature span—from −70 °C to +150 °C. Its compact internal volume (400 × 500 × 400 mm) enables rapid thermal response while maintaining high reproducibility in laboratory-scale qualification testing. The chamber meets baseline mechanical and thermal performance criteria aligned with IEC 60068-2-1 (cold tests), IEC 60068-2-2 (dry heat), and ASTM D3418 (thermal transitions of polymers), making it suitable for pre-compliance screening in R&D, QC labs, and small-batch validation environments.

Key Features

• High-efficiency cascade refrigeration system enabling reliable sub-zero operation down to −70 °C without liquid nitrogen or external chillers
• PID-based digital temperature controller with real-time monitoring, programmable ramp/soak profiles, and auto-tuning capability
• Stainless steel interior chamber (SUS304) with insulated double-wall construction and silicone-sealed door gasket for minimal thermal leakage
• Thermal uniformity maintained within ±2.0 °C across the working volume, verified per ISO 16750-4 Annex A methodology
• Temperature stability of ±0.5 °C (fluctuation) and ±2 °C (deviation from setpoint) under steady-state conditions
• Integrated over-temperature, over-pressure, and compressor overload protection circuits compliant with EN 61000-6-2 EMC immunity requirements
• Front-access design with observation window and internal LED lighting for non-intrusive sample monitoring

Sample Compatibility & Compliance

The PG-80 accommodates a broad range of sample types—including PCBs, sensors, battery cells, polymer films, optical components, and small mechanical subassemblies—within its 80 L working volume. Samples are mounted on standard stainless steel trays or custom fixtures compatible with ISO/IEC 17025-accredited lab practices. While the base model is dry-cycle only (non-humidity-controlled), its structural and control architecture conforms to key environmental test standards including MIL-STD-810G Method 502.6 (low temperature), Method 501.6 (high temperature), and JIS C 0021. Optional data logging modules support audit-ready traceability required under GLP and GMP frameworks. All electrical safety design complies with IEC 61010-1:2010 for laboratory equipment.

Software & Data Management

The PG-80 operates via a built-in 7-inch color touchscreen HMI with intuitive navigation and multi-level user access (operator, engineer, administrator). Temperature profiles can be created, stored, and recalled locally (up to 100 programs, each with 99 segments). Optional RS485/Modbus RTU or Ethernet (TCP/IP) interface enables integration into centralized lab management systems. When paired with LabCompanion’s optional PC-based LogView Pro software (v3.2+), users gain real-time remote monitoring, automated CSV report generation, timestamped alarm history, and 21 CFR Part 11–compliant electronic signatures for audit trails. Data export supports common formats including .csv, .xls, and .pdf for inclusion in IQ/OQ documentation packages.

Applications

• Accelerated aging studies of elastomers, adhesives, and encapsulants per ASTM D573 and ISO 188
• Thermal cycling reliability assessment of surface-mount devices (SMDs) and automotive ECUs
• Pre-screening of lithium-ion battery cells prior to full-scale thermal runaway testing
• Validation of material dimensional stability (e.g., coefficient of thermal expansion) in metrology labs
• Calibration verification of temperature-sensitive sensors and transducers
• Supporting failure analysis workflows by replicating field-deployed thermal extremes in controlled benchtop settings

FAQ

What is the maximum allowable sample mass for stable thermal performance?
For optimal uniformity and response time, total sample mass should not exceed 15 kg. Heavier loads may extend stabilization time and marginally affect uniformity—verified per internal calibration protocol.
Can the PG-80 be integrated into a LIMS or MES environment?
Yes—via optional Modbus TCP or RS485 interfaces, with full register mapping documentation provided for seamless SCADA or LabWare integration.
Is third-party calibration certification available?
LabCompanion offers NIST-traceable calibration certificates (per ISO/IEC 17025) for temperature sensors and controllers, including as-found/as-left data and uncertainty budgets.
Does the unit comply with CE marking requirements?
Yes—the PG-80 carries CE marking under the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU, with technical files available upon request.
What maintenance intervals are recommended for long-term reliability?
Compressor oil and refrigerant levels should be inspected annually; air filters cleaned every 3 months; and chamber seals checked semiannually for compression integrity and surface degradation.
