Overview
The LabCompanion PM-225 High-Low Temperature Environmental Test Chamber is an engineered solution for controlled thermal stress testing of materials, components, and finished products under defined temperature extremes. 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 chamber utilizes a dual-stage compressor refrigeration system coupled with PID-controlled electric heating to achieve stable, repeatable thermal profiles across its full operating range of −20 °C to +150 °C. Its robust double-wall insulated construction—featuring high-density polyurethane foam (≥100 mm thickness) and stainless steel inner chamber—minimizes thermal leakage and ensures long-term stability during extended dwell cycles. The chamber is intended for use in quality assurance laboratories, R&D facilities, and production line validation environments where compliance with ASTM D3418, IPC-TM-650 2.6.7, and MIL-STD-810G Method 502.6 is routinely required.
Key Features
- Stable thermal control architecture delivering ±0.5 °C temperature fluctuation and ±2.0 °C uniformity across the full working volume
- Programmable ramp-and-soak capability with adjustable heating rate (1.0–3.0 °C/min) and cooling rate (1.2 °C/min)
- Double-skin chamber design with SUS304 stainless steel interior and electrogalvanized steel exterior for corrosion resistance and structural integrity
- Intelligent microprocessor-based controller with real-time data logging, alarm history, and password-protected parameter settings
- Over-temperature, over-pressure, and compressor overload protection circuits compliant with UL 61010-1 and EN 61000-6-3 EMC standards
- Optional RS485 interface supporting Modbus RTU protocol for integration into centralized lab monitoring systems
Sample Compatibility & Compliance
The PM-225 accommodates samples up to 600 mm (W) × 750 mm (H) × 500 mm (D), with maximum payload capacity of 50 kg (distributed load). It supports standardized test specimens per ISO 22088-3 (plastics — environmental stress cracking), JIS C 0042 (electronic components), and GB/T 2423.1–2022 / GB/T 2423.2–2022 (Chinese national equivalents of IEC 60068-2). Chamber airflow is optimized via rear-mounted centrifugal fans with adjustable baffle plates to ensure minimal turbulence and uniform convective heat transfer—critical for validating thermal aging behavior of polymers, PCB assemblies, and automotive ECUs. All units undergo factory calibration traceable to NIM (National Institute of Metrology, China) and include a Certificate of Conformance with initial verification data.
Software & Data Management
The embedded controller supports local operation without external software; however, optional PC-based LabCompanion ThermalSuite™ software enables advanced test sequencing, multi-chamber synchronization, and automated report generation in PDF or CSV format. Data export includes timestamped temperature readings at user-defined intervals (1 s to 60 min), event logs (door open/close, alarm triggers), and deviation alerts aligned with GLP-compliant audit trail requirements. When configured with optional Ethernet module, the system supports secure HTTPS access and can be integrated into enterprise LIMS platforms via RESTful API. All stored data retains integrity under FDA 21 CFR Part 11 principles when electronic signatures and role-based access controls are enabled.
Applications
- Thermal cycling qualification of lithium-ion battery modules per UN 38.3 Section 38.3.4
- Pre-conditioning of adhesives, sealants, and elastomers prior to tensile or peel testing (ASTM D412, ASTM D903)
- Accelerated aging studies of medical device packaging per ISO 11607-1
- Environmental screening of aerospace avionics per DO-160G Section 4.3 (Temperature Variation)
- Reliability validation of consumer electronics enclosures under storage and operational temperature limits
- Material compatibility testing for pharmaceutical primary packaging (USP , ICH Q5C)
FAQ
What is the standard calibration interval recommended for the PM-225?
LabCompanion recommends annual calibration using NIST-traceable reference thermometers; internal sensor verification can be performed quarterly using a calibrated handheld probe.
Can the chamber operate continuously at −20 °C or +150 °C?
Yes—the system is rated for indefinite continuous operation at both temperature extremes, provided ambient room conditions remain within 15–30 °C and relative humidity ≤80% RH.
Is third-party certification (e.g., CE, UKCA) available?
CE marking is applied to all export units; UKCA and EAC certifications can be arranged upon request with additional lead time and documentation review.
Does the controller support custom test profiles with multiple segments?
Yes—the built-in program editor allows up to 99 steps per profile, including ramp, soak, and loop functions, with independent setpoint, rate, and duration parameters.
What maintenance is required for the compressor-based cooling system?
Routine maintenance includes quarterly condenser coil cleaning, annual refrigerant pressure verification, and biennial replacement of the desiccant filter—detailed in the included Maintenance Logbook and Service Manual.
