Overview
The LabCompanion TH-600-12 is a precision-engineered benchtop temperature and humidity environmental test chamber designed for accelerated reliability testing of electronic components, polymers, automotive parts, medical devices, and packaging materials under controlled thermal and hygrothermal stress conditions. It operates on a dual-refrigeration and steam-humidification architecture, enabling rapid transitions between extreme thermal states while maintaining high-fidelity humidity control across the full operational envelope. The chamber employs a cascade refrigeration system with PID-controlled electric heating and ultrasonic humidification to achieve stable, repeatable conditioning cycles per IEC 60068-2, MIL-STD-810, and ISO 16750 standards. Its core function is to simulate real-world environmental aging—such as diurnal cycling, condensation-prone tropical climates, or cold-start thermal shock—within a compact, laboratory-scale footprint.
Key Features
- Wide operational range: −70 °C to +150 °C temperature; 20–98% RH humidity (non-condensing at low temperatures)
- High reproducibility: ±0.5 °C temperature fluctuation (measured at chamber center, no load, ambient +25 °C), compliant with GB/T 5170.2–2008 test methodology
- Traceable humidity control: Humidity deviation specified as ±3.0% RH below 75% RH and ±5.0% RH at or above 75% RH, validated per GB/T 5170.5–2017
- Programmable thermal ramp rates: Selectable linear or non-linear heating profiles at 5, 10, 15, 20, or 25 °C/min; optional liquid nitrogen assist enables cooling rates up to 30 °C/min for thermal shock qualification
- Benchtop form factor with internal dimensions of 600 W × 800 H × 500 D mm (23.6″ × 31.5″ × 19.7″), optimized for integration into QA labs and R&D workspaces with limited floor space
- Robust stainless-steel inner chamber with double-wall insulation, electrostatically coated outer enclosure, and sealed door gasketing to minimize thermal leakage and moisture ingress
Sample Compatibility & Compliance
The TH-600-12 accommodates standard test specimens up to 15 kg without compromising air uniformity or sensor response time. Its chamber geometry and airflow design ensure ≤±2 °C spatial temperature uniformity (per IEC 60068-3-5) and ≤±4% RH spatial humidity uniformity across the working volume. All control firmware and calibration records support GLP-compliant documentation requirements. The unit meets electromagnetic compatibility (EMC) per EN 61326-1 and safety compliance per IEC 61010-1. Optional validation packages include IQ/OQ documentation aligned with FDA 21 CFR Part 11 data integrity guidelines, supporting regulated environments in pharmaceutical packaging stability studies and medical device biocompatibility testing.
Software & Data Management
Equipped with an embedded 7-inch color touchscreen HMI running LabCompanion’s proprietary TC-OS v4.2 firmware, the TH-600-12 supports up to 100 multi-step test programs with nested loops, dwell times, and conditional branching (e.g., “hold until RH reaches 85%”). Real-time data logging records temperature, humidity, setpoint, and alarm status at user-defined intervals (1 s to 60 min). Export formats include CSV and PDF reports with digital signatures. USB and Ethernet interfaces enable remote monitoring via LabCompanion’s PC-based ControlSuite software, which provides audit trail functionality, user access levels (admin/operator/observer), and automatic backup to network drives—fully traceable for GMP audits.
Applications
- Accelerated life testing of PCB assemblies under temperature-humidity bias (THB) per JESD22-A110

- Automotive component qualification per ISO 16750-4 (climate resistance)
- Pharmaceutical primary packaging stability per ICH Q1A(R2) long-term and accelerated storage conditions
- Adhesive bond strength degradation analysis under cyclic hygrothermal loading
- Validation of hermetic seal integrity in MEMS sensors and optoelectronic housings
FAQ
What is the maximum allowable sample mass inside the TH-600-12 without affecting thermal uniformity?
The chamber maintains specified uniformity and recovery performance with loads up to 15 kg, provided samples are arranged to permit unobstructed airflow around all surfaces.
Can the TH-600-12 perform thermal shock testing?
Yes—when configured with the optional liquid nitrogen assist module, it achieves cooling rates up to 30 °C/min, enabling two-zone thermal shock protocols per MIL-STD-810H Method 503.7.
Is humidity control active below 0 °C?
Humidity generation is disabled below +5 °C to prevent condensation and ice formation on sensors and humidifier elements; however, dry cold storage down to −70 °C remains fully functional.
Does the system support third-party SCADA integration?
Yes—Modbus TCP and OPC UA drivers are available upon request for integration into enterprise MES or LIMS platforms.
How often does the chamber require recalibration?
Annual calibration against NIST-traceable reference standards is recommended; internal self-diagnostics run at startup and monitor sensor drift continuously.
