LabCompanion TH-800-3 High-Low Temperature Environmental Test Chamber

Overview

The LabCompanion TH-800-3 High-Low Temperature Environmental Test Chamber is an engineered thermal stress platform designed for precise, repeatable simulation of extreme ambient temperature conditions in laboratory and industrial R&D environments. Based on forced-air convection with dual-stage refrigeration and PID-controlled electric heating, the system delivers stable thermal profiles across a wide operational range—from cryogenic −70 °C to high-temperature +150 °C—enabling accelerated life testing, qualification validation, and material stability assessment per international environmental test standards including IEC 60068-2-1 (cold), IEC 60068-2-2 (dry heat), and MIL-STD-810H Method 501.5/502.5. Its robust chamber architecture, stainless-steel interior, and insulated double-wall construction minimize thermal leakage and ensure long-term calibration integrity under continuous cycling duty.

Key Features

• Wide operational temperature range: −70 °C to +150 °C with independent refrigeration and heating subsystems
• High-precision temperature control: ±0.5 °C fluctuation and ±2.0 °C deviation across full load, verified via NIST-traceable sensor calibration
• Uniform thermal distribution: ≤2.0 °C spatial uniformity measured at nine standardized points (per IEC 60068-3-5)
• Programmable ramp rates: Adjustable linear and non-linear heating/cooling profiles from 1 to 25 °C/min, supporting both step-stress and gradient-based test protocols
• Large working volume: 800 L internal chamber (1000 mm × 1000 mm × 800 mm) accommodating full-size PCB assemblies, automotive ECUs, battery modules, and aerospace structural components
• Integrated safety architecture: Over-temperature cut-off, compressor high-pressure protection, door interlock, and real-time fault logging compliant with IEC 61000-6-2/6-4 EMC requirements

Sample Compatibility & Compliance

The TH-800-3 accommodates diverse sample geometries—including stacked test boards, sealed enclosures, metal housings, and polymer-packaged devices—without requiring internal modifications. Its chamber design supports passive and active thermal monitoring via external thermocouple feedthroughs (optional). The system conforms to ISO 9001:2015 quality management, ISO 14001:2015 environmental management, and ISO 45001:2018 occupational health and safety frameworks. It meets essential performance criteria referenced in ASTM D3418 (thermal transitions of polymers), IPC-9701A (reliability qualification of surface mount solder attachments), and JEDEC JESD22-A104E (temperature cycling). Full documentation packages—including factory acceptance test (FAT) reports, calibration certificates, and IQ/OQ protocol templates—are provided to support GLP/GMP-regulated environments.

Software & Data Management

Equipped with LabCompanion’s proprietary TC-Link™ control software (Windows-based), the TH-800-3 enables intuitive multi-segment profile programming, real-time data visualization, and automated report generation in PDF/CSV formats. The system logs timestamped temperature readings at user-defined intervals (1–60 seconds), stores ≥10,000 hours of historical data onboard, and supports Ethernet/IP and RS-485 Modbus RTU communication for integration into centralized MES or LIMS platforms. Audit trail functionality complies with FDA 21 CFR Part 11 requirements when deployed with Windows domain authentication and electronic signature configuration. Remote monitoring and alarm notification via SMTP email or SNMP traps are configurable without third-party middleware.

Applications

This chamber serves critical roles across electronics reliability engineering (e.g., solder joint fatigue evaluation under thermal cycling per IPC-9701), battery thermal runaway propagation studies (UN 38.3 thermal test simulation), aerospace component qualification (DO-160 Section 4.3 temperature extremes), and pharmaceutical packaging stability testing (ICH Q1A–Q1E guidelines). It is routinely deployed by national metrology institutes—including China National Institute of Metrology—for reference sensor calibration verification, and by Tier-1 automotive suppliers for AEC-Q200-compliant passive component screening. Universities utilize it for fundamental research in polymer crystallinity kinetics, phase-change material behavior, and low-temperature semiconductor mobility characterization.

FAQ

What is the standard calibration interval recommended for the TH-800-3?

LabCompanion recommends annual calibration using traceable reference sensors; optional on-site calibration services are available through authorized service centers in Shanghai, Chengdu, and Xi’an.
Can the chamber be integrated into an existing lab automation network?

Yes—the system supports Modbus TCP, OPC UA (via optional gateway), and HTTP API endpoints for bidirectional command and status exchange with SCADA or LabVIEW-based control systems.
Is humidity control available as an upgrade?

No—the TH-800-3 is a dry-temperature-only chamber. For combined temperature/humidity testing, LabCompanion offers the THS series (e.g., THS-800-3) with integrated steam humidification and dehumidification modules.
Does the unit comply with CE marking requirements?

Yes—it carries CE marking under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU, with technical documentation available upon request.
What maintenance is required to sustain specified temperature uniformity?

Quarterly inspection of air filter integrity, annual refrigerant pressure verification, and biannual verification of fan motor balance and duct seal integrity are outlined in the preventive maintenance manual (PM-TH800-Rev.3).
