Overview
The LabCompanion TH-1000-20 is a benchtop rapid temperature and humidity cycling chamber engineered for precise environmental stress testing of materials, electronic components, packaging systems, and small-scale prototypes under dynamically controlled thermal and hygrometric conditions. It operates on a dual-refrigeration + electric heating + steam humidification architecture, enabling independent regulation of temperature (−70 °C to +150 °C) and relative humidity (20–98% RH) across programmable test profiles. Unlike conventional steady-state chambers, the TH-1000-20 supports accelerated thermal transitions—up to 25 °C/min heating rate—with optional liquid nitrogen assist for sub-zero cooling rates up to 30 °C/min. Its control system complies with IEC 60068-3-5 (Environmental testing — Part 3-5: Supporting documentation and guidance — Thermodynamic properties of moist air) and aligns with test method requirements in MIL-STD-810H, JEDEC JESD22-A104F, and ISO 16750-4 for automotive electronics qualification.
Key Features
- High-fidelity dual PID control loop for simultaneous temperature and humidity regulation, minimizing cross-coupling effects during rapid transitions
- Benchtop footprint (W600 × D500 × H600 mm internal volume) optimized for laboratory space constraints without compromising chamber uniformity (±1.5 °C / ±4% RH across working volume per GB/T 5170.2–2008 and GB/T 5170.5–2017)
- Stainless steel 304 inner chamber with seamless welded construction and anti-condensation double-glazed observation window
- Programmable multi-segment profiles supporting up to 99 cycles, with user-defined ramp/soak/humidity hold sequences and automatic restart after power interruption
- Integrated safety interlocks including over-temperature cutoff, humidity sensor fault detection, refrigerant pressure monitoring, and door-open alarm with automatic compressor shutdown
- Optional LN₂-assisted cooling module enables extended low-temperature ramping capability down to −55 °C at ≥20 °C/min, meeting stringent thermal shock validation protocols
Sample Compatibility & Compliance
The TH-1000-20 accommodates samples up to 10 kg with unrestricted airflow access via rear-mounted centrifugal blower and perforated stainless steel shelf (standard configuration). It supports non-intrusive monitoring through 2× Ø50 mm test ports (with silicone gaskets) for external sensor feedthrough or real-time electrical performance logging. The chamber meets electromagnetic compatibility requirements per EN 61326-1 and conforms to safety standards EN 61010-1 for laboratory equipment. Calibration traceability follows ISO/IEC 17025 principles, with optional factory calibration certificates available for temperature (Pt100 Class A sensors) and humidity (capacitive polymer sensors, NIST-traceable). It supports GLP-compliant audit trails when paired with validated software (see Software & Data Management section).
Software & Data Management
Equipped with LabCompanion’s proprietary WinTest Pro v4.2 control software (Windows 10/11 compatible), the TH-1000-20 provides full remote operation via Ethernet or USB interface. The software features real-time graphing of all monitored parameters, automated report generation (PDF/CSV), and configurable alarm notifications via email or SMS gateway. All setpoints, actual values, alarms, and operator actions are time-stamped and stored with SHA-256 hashing to ensure data integrity. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements—including electronic signatures, role-based access control, and immutable log archiving—for regulated environments such as medical device R&D and pharmaceutical packaging validation.
Applications
- Accelerated aging of polymer films, adhesives, and conformal coatings under cyclic humidity exposure
- Thermal shock screening of PCB assemblies and semiconductor packages per JEDEC J-STD-020 and IPC-9701
- Validation of moisture barrier performance in flexible electronics encapsulation
- Reliability testing of lithium-ion battery cells under combined thermal-hygrometric stress
- Stability assessment of diagnostic reagents and lyophilized biologics per ICH Q1A(R2) guidelines
- Qualification of automotive ECUs per ISO 16750-4 (road vehicles — environmental conditions and testing for electrical and electronic equipment)
FAQ
What is the maximum achievable cooling rate with the standard configuration?
Standard refrigeration achieves ≤15 °C/min from +25 °C to −40 °C; optional LN₂ assist extends this to ≥20 °C/min down to −55 °C.
Does the chamber support humidity control below 0 °C?
Humidity control is disabled below 0 °C ambient to prevent ice formation on sensors and humidifier elements; dew point control is not implemented.
Can third-party data loggers interface with the TH-1000-20?
Yes—Modbus TCP and RS-485 interfaces are provided for integration with external SCADA or LIMS platforms.
Is ISO 17025 calibration included with purchase?
Factory calibration is performed pre-shipment; ISO/IEC 17025-accredited calibration is available as an add-on service with documented uncertainty budgets.
How is chamber uniformity verified during installation qualification (IQ)?
A 9-point sensor mapping protocol (per ASTM E2297) is recommended using NIST-traceable thermohygrometers; LabCompanion provides IQ/OQ templates compliant with Annex 11 and EU GMP Annex 15.
