LabCompanion TH-1000 High-Low Temperature Cycling Chamber

Overview

The LabCompanion TH-1000 High-Low Temperature Cycling Chamber is an engineered environmental test system designed for precise, repeatable thermal stress evaluation of materials, components, and finished products across industrial R&D, quality assurance, and reliability validation workflows. Operating on a dual-stage compressor-based refrigeration architecture with PID-controlled forced-air circulation, the chamber delivers stable thermal profiles within a wide operational envelope—from cryogenic −70 °C to elevated +150 °C. Its thermally insulated stainless-steel interior, coupled with high-efficiency insulation and calibrated platinum resistance temperature sensors (PT100), ensures minimal thermal lag and high reproducibility in both static and dynamic temperature cycling protocols. The TH-1000 conforms to fundamental thermal testing requirements outlined in IEC 60068-2-1 (Cold), IEC 60068-2-2 (Dry Heat), and ASTM D3418 (Transition Temperatures of Polymers), serving as a foundational platform for accelerated aging, thermal shock simulation, and qualification testing under controlled ambient conditions.

Key Features

• Robust dual-stage compressor refrigeration system enabling continuous operation at −70 °C without liquid nitrogen or external chillers
• PID-driven temperature control with real-time feedback from multiple PT100 sensors distributed across the working chamber
• Forced-air convection system with adjustable airflow velocity and directional baffles to maintain ±2.0 °C temperature uniformity (per IEC 60068-3-5)
• Stainless-steel inner chamber (SUS304) with seamless welding and anti-condensation heating on observation window and door seal
• Programmable 10-segment, 99-cycle thermal profile capability with ramp/soak/handling logic support
• Integrated safety interlocks including over-temperature cut-off, compressor high-pressure protection, and door-open alarm
• Front-access cable port (Φ50 mm) with silicone gasket for external sensor integration and real-time monitoring

Sample Compatibility & Compliance

The TH-1000 accommodates samples up to 1000 mm × 1000 mm × 1000 mm in volume—including PCB assemblies, automotive ECUs, lithium-ion battery modules, polymer specimens, and packaged consumer electronics. Its standard configuration meets general-purpose laboratory safety and electromagnetic compatibility requirements per EN 61000-6-3 and EN 61000-6-2. While not certified for Class I Division 1 hazardous locations, optional modifications—such as intrinsically safe sensor interfaces and non-sparking internal hardware—can be implemented upon request to align with ATEX/IECEx preliminary assessment criteria. Calibration documentation follows ISO/IEC 17025 traceability pathways through accredited third-party laboratories; factory calibration certificates include as-found/as-left data and uncertainty budgets per ANSI/NCSL Z540.

Software & Data Management

The chamber integrates with LabCompanion’s TC-Studio v4.2 software suite via RS485 (Modbus RTU) or optional Ethernet (TCP/IP) interface. TC-Studio provides full remote operation, real-time trending, and automated report generation compliant with 21 CFR Part 11 Annex 11 requirements—including electronic signatures, audit trails, and role-based user permissions. All temperature logs are timestamped with millisecond resolution and stored in CSV and PDF formats. Data integrity safeguards include cyclic redundancy check (CRC) validation during transmission and write-protected archival mode to prevent post-test modification. Optional cloud synchronization enables secure cross-site data aggregation for multi-lab reliability programs under ISO 9001 and IATF 16949 frameworks.

Applications

• Thermal cycling qualification of aerospace avionics per MIL-STD-810H Method 502.7
• Storage stability assessment of pharmaceutical packaging under ICH Q1A(R2) long-term and accelerated conditions
• Material coefficient of thermal expansion (CTE) characterization using embedded strain gauges or digital image correlation (DIC)
• Pre-conditioning of sensors and MEMS devices prior to functional testing
• Validation of thermal interface material (TIM) performance under repeated thermal load
• Environmental stress screening (ESS) for electronic subassemblies in accordance with Telcordia GR-63-CORE

FAQ

What is the maximum sample weight the TH-1000 can accommodate without compromising thermal uniformity?
The chamber supports static loads up to 150 kg distributed evenly on the standard stainless-steel shelf; exceeding this may require structural reinforcement and recalibration of airflow dynamics.
Can the TH-1000 perform thermal shock testing between −70 °C and +150 °C?
While rated for sequential cycling, the TH-1000 is not configured as a two-zone thermal shock chamber; rapid transition between extreme setpoints requires optional auxiliary heating/cooling enhancements and is subject to individual validation per test plan.
Is third-party IQ/OQ/PQ documentation available for GMP-regulated environments?
Yes—LabCompanion provides customizable qualification packages aligned with FDA guidance for computerized systems, including protocol templates, executed reports, and evidence of instrument-specific risk assessment (per ISO 14971).
