Overview
The Haida HD-E702-1000K40/60 Programmable Temperature and Humidity Chamber is an engineered environmental simulation system designed for rigorous reliability validation of materials, components, and finished products under controlled thermal and hygrothermal stress conditions. It operates on the principle of precision-coupled refrigeration, resistive heating, and steam-based humidification—integrated via a dual-stage mechanical cooling architecture and high-fidelity closed-loop feedback control. The chamber meets the physical test requirements defined in international standards including IEC 60068-2, MIL-STD-810G (via GJB 150 series equivalency), and ISO 16750-4 for automotive electronics qualification. Its nominal 1000 L internal volume (1000 mm × 1000 mm × 1000 mm) supports full-size PCB assemblies, automotive ECUs, aerospace structural composites, and battery modules—enabling both steady-state conditioning and dynamic cycling across −60 °C to +150 °C and 20–98% RH.
Key Features
- Robust Dual-Stage Refrigeration Architecture: Equipped with two imported Tecumseh (France) hermetic compressors (3 HP each), optimized for rapid thermal transition. Uses environmentally compliant R404a/R23 mixed-refrigerant circuits with brazed-plate heat exchangers, finned-tube evaporators, and air-cooled condensers with axial-flow cooling fans.
- Precision Climate Control: PID + Fuzzy logic algorithm implemented in the Taiwan UYI 7-inch capacitive touchscreen controller ensures stable setpoint tracking. Temperature resolution: 0.01 °C; humidity resolution: 0.1% RH. Achieves ±0.5 °C temperature deviation and ±2% RH humidity deviation per IEC 60068-3-5.
- Corrosion-Resistant Construction: Interior chamber fabricated from 1.0 mm SUS304 stainless steel; exterior from 1.0 mm cold-rolled steel with electrostatic epoxy-polyester coating. Dual-layer vacuum-insulated observation window with conductive ITO film for anti-fogging; silicone gasket sealing rated for continuous operation at −60 °C and +150 °C.
- Modular Sample Handling: Two adjustable stainless-steel wire mesh shelves (load capacity ≥20 kg/shelf, uniformly distributed); Φ100 mm cable/port access port with insulated plug and thermal barrier collar; optional auxiliary instrumentation mounting rails available upon request.
- Comprehensive Safety & Diagnostics: Integrated protection includes compressor high-pressure/overload cutoff, phase failure/reverse-phase detection, fan overheat shutdown, chamber overtemperature interlock, leakage current protection, and auto-fail-safe stop on critical fault detection. All events logged with timestamps in non-volatile memory.
Sample Compatibility & Compliance
The HD-E702-1000K40/60 accommodates diverse sample geometries—from miniature semiconductor packages to 19-inch rack-mounted telecom equipment—within its cubic workspace. Its uniformity performance (≤2 °C temp, ±3% RH) satisfies Class II requirements per IEC 60068-3-5 for climatic testing chambers. The system is routinely deployed in laboratories conducting qualification per ASTM D4332 (conditioning of plastics), IPC-9701 (accelerated reliability of printed boards), UL 1642 (lithium battery environmental stress), and AEC-Q200 (passive component stress testing). Full compliance documentation—including calibration traceability to NIM (China National Institute of Metrology) and factory verification reports per ISO/IEC 17025—is supplied with each unit. Optional IQ/OQ documentation packages support GLP/GMP-regulated environments.
Software & Data Management
Data acquisition and analysis are enabled via embedded 2 GB SD card logging (expandable), supporting real-time recording of temperature, humidity, elapsed time, program segment ID, and alarm status at user-selectable intervals (1 s to 60 min). Export formats include CSV and native .DAT files compatible with MATLAB, Python (pandas), and LabVIEW. The UYI controller supports RS-232/485 serial communication for remote monitoring and SCADA integration. Optional PC software provides graphical overlay of multiple test runs, statistical process control (SPC) charting, and automated report generation compliant with FDA 21 CFR Part 11 audit trail requirements—including electronic signature, user role management, and immutable event logs.
Applications
- Accelerated life testing of lithium-ion battery cells and packs under thermal-hygric stress

- Stress screening of automotive ADAS sensors (radar, LiDAR, camera modules) across operational envelopes
- Material compatibility testing of conformal coatings, potting compounds, and encapsulants
- Validation of medical device sterilization packaging integrity during accelerated aging (ISO 11607)
- Environmental stress screening (ESS) of PCBAs prior to burn-in or functional testing
FAQ
What is the maximum allowable sample mass without compromising chamber uniformity?
For optimal thermal/humidity homogeneity, total sample mass should not exceed 40 kg. Load distribution must be symmetrical and avoid blocking air inlet/outlet grilles.
Can the chamber operate continuously at −60 °C and 10% RH?
The specified low-humidity limit is 20% RH at sub-zero temperatures due to dew-point constraints in the steam-generation system. For <20% RH, desiccant-assisted dehumidification modules are available as factory-installed options.
Is third-party calibration certification included with delivery?
Yes—each unit ships with a NIM-traceable factory calibration certificate covering temperature (−60 °C to +150 °C) and humidity (20–98% RH) at three points per range, performed using Fluke 1524 and Rotronic HC2-S probes.
How is firmware updated, and is version history maintained?
Firmware updates are delivered via encrypted USB stick with SHA-256 checksum verification. Controller firmware revision, update date, and changelog are accessible in the “System Info” menu and retained across power cycles.
Does the system support automated pass/fail evaluation against test specifications?
Yes—the optional TestGuard™ software module enables rule-based tolerance checking (e.g., “hold at 85 °C/85% RH for 96 h ±5 min; max deviation ≤0.8 °C/±1.5% RH”) with configurable alert escalation and PDF report auto-generation.
