Overview
The LabCompanion TH-180-5 Temperature and Humidity Cycling Chamber is an engineered environmental test system designed for precise, repeatable simulation of dynamic thermal and hygrothermal stress conditions. Based on forced-air convection with dual independent PID-controlled refrigeration and humidification subsystems, it enables programmable temperature-humidity profiles—including rapid transitions, dwell periods, and cyclic ramps—essential for reliability validation in electronics, automotive components, polymer packaging, and aerospace materials. The chamber operates across a standard temperature range of –70°C to +150°C and a humidity range of 20–98% RH, supporting both steady-state conditioning and accelerated life testing per IEC 60068-2-1, IEC 60068-2-2, IEC 60068-2-30, and MIL-STD-810H methodologies. Its benchtop footprint (W600 × D500 × H600 mm internal) delivers high volumetric efficiency without compromising structural integrity or thermal uniformity.
Key Features
- Programmable multi-segment cycling: Up to 999 cycles with 99 steps per cycle, supporting custom ramp/dwell/humidity hold sequences
- Dual independent control architecture: Separate PID loops for temperature and humidity ensure minimal cross-coupling and stable setpoint maintenance
- High-fidelity sensor network: PT100 temperature sensors and capacitive RH transducers calibrated traceably to NIST standards
- Refrigeration system: High-efficiency cascade compressor with optional liquid nitrogen assist for cooling rates up to 30°C/min (–55°C to +125°C transition)
- Humidification system: Ultrasonic mist generator with deionized water reservoir and automatic drain control to prevent mineral buildup
- Robust chamber construction: Double-wall insulated stainless steel interior (SUS304), electrostatically painted exterior, and silicone-sealed observation window
- Real-time monitoring interface: 7-inch color touchscreen with intuitive graphical programming, data logging, and USB export capability
Sample Compatibility & Compliance
The TH-180-5 accommodates a wide variety of sample geometries and material classes—including PCB assemblies, lithium-ion battery cells, medical device housings, and elastomeric seals—without requiring external adapters or fixtures. Internal dimensions (600 × 500 × 600 mm) allow for standardized test specimens per ASTM D4332, ISO 2231, and GB/T 5170.5–2016. All performance specifications—including temperature fluctuation (±0.5°C), humidity deviation (±3.0% RH below 75% RH; ±5.0% RH at or above), and uniformity (±2.0°C / ±4.0% RH across working volume)—are verified under no-load conditions per GB/T 5170.2–2008 and GB/T 5170.5–2016. The unit supports GLP-compliant operation through configurable audit trails, user access levels, and electronic signature readiness.
Software & Data Management
The embedded controller firmware includes built-in data logging at user-selectable intervals (1 s to 60 min), with storage capacity for ≥10,000 hours of timestamped temperature and humidity records. Export formats include CSV and PDF reports compatible with LIMS integration. Optional PC-based software (LabCompanion TestSuite v3.2) provides advanced features: remote monitoring via Ethernet/Wi-Fi, automated report generation aligned with ISO/IEC 17025 requirements, real-time alarm notification (email/SMS), and full 21 CFR Part 11 compliance—including electronic signatures, role-based permissions, and immutable audit logs. Data encryption (AES-256) and secure firmware updates ensure long-term regulatory alignment.
Applications
- Electronics: Thermal shock screening of solder joints, conformal coating adhesion assessment, and moisture sensitivity level (MSL) testing per J-STD-020
- Automotive: Validation of infotainment displays, sensor housings, and EV battery modules under combined thermal-hygric stress
- Pharmaceutical packaging: Accelerated stability studies for blister packs and HDPE containers per ICH Q1A(R2)
- Polymer R&D: Evaluation of dimensional stability, creep behavior, and hydrolytic degradation kinetics in thermoplastics and composites
- Quality assurance: Routine qualification of incoming raw materials, in-process verification, and final product release testing
FAQ
What is the maximum achievable cooling rate with the optional LN₂ assist system?
With liquid nitrogen auxiliary cooling, the TH-180-5 achieves a nominal cooling rate of up to 30°C/min between –55°C and +125°C under no-load conditions.
Does the chamber support humidity control below 20% RH?
No—the specified humidity range is 20–98% RH. Sub-20% RH operation requires optional desiccant-based dry air purge systems, available as a factory-installed upgrade.
Can test profiles be imported from external sources such as Excel or MATLAB?
Yes—LabCompanion TestSuite supports direct import of time-temperature-humidity sequences in CSV format, enabling seamless integration with simulation-derived stress profiles.
Is calibration certification included with shipment?
A factory-issued calibration certificate (traceable to national standards) is provided with each unit. UKAS or ISO/IEC 17025 accredited third-party calibration is available upon request.
How is temperature uniformity validated across the working volume?
Uniformity is measured using nine PT100 probes positioned at defined locations per GB/T 5170.2–2008; results are documented in the acceptance test report shipped with the unit.
