Haida HD-E702-1000B40/60 Programmable Temperature and Humidity Chamber

Overview

The Haida HD-E702-1000B40/60 Programmable Temperature and Humidity Chamber is an industrial-grade environmental simulation system engineered for precise, repeatable, and traceable climatic conditioning of materials and components under controlled thermal and hygroscopic stress. Designed in accordance with international environmental testing standards—including IEC 60068-2, MIL-STD-810G, and GB/T 2423 series—the chamber employs a dual-refrigeration circuit architecture (mechanical two-stage cascade cooling) to achieve stable operation across an extended temperature range of −60 °C to +150 °C and a humidity range of 20–98% RH. Its thermodynamic performance is validated through continuous thermal mapping per ISO 17025-accredited procedures, ensuring spatial uniformity (≤2 °C temperature, ±3% RH humidity) and temporal stability (±0.5 °C/±2% RH deviation). The chamber supports both steady-state (constant mode) and dynamic profile-based testing—enabling accelerated aging, thermal shock pre-conditioning, condensation cycling, and combined temperature-humidity stress protocols essential for reliability qualification in electronics, aerospace composites, automotive ECUs, and medical device packaging.

Key Features

• Robust dual-wall construction: 1.0 mm SUS304 stainless steel interior and exterior panels, welded and passivated for corrosion resistance and long-term cleanliness compliance (ISO 14644 Class 8 compatible).
• High-efficiency insulation: 100 mm polyurethane rigid foam core + 100 mm high-density glass fiber blanket, minimizing thermal bridging and enabling low standby energy consumption (<1.2 kW/h at 25 °C/50% RH).
• Optimized airflow design: Forward-curved centrifugal blower with adjustable multi-directional nozzles ensures laminar, turbulence-free circulation—critical for uniform moisture distribution and avoiding localized condensation on test specimens.
• Isolated humidification system: Stainless-steel immersion heater with MgO-insulated NiCr element and automatic water replenishment via front-access reservoir; prevents mineral scaling and enables uninterrupted 96-hour RH hold tests.
• Intelligent control architecture: UYI 7-inch capacitive touchscreen controller with dual PID + fuzzy logic algorithm, supporting up to 120 user-defined programs (1200 total segments), slope-controlled ramp/soak profiles, and power-fail recovery with timestamped resume.
• Comprehensive safety redundancy: Triple-layer protection including compressor high-pressure cut-off, phase-loss/phase-reversal detection, overtemperature interlock (independent mechanical thermostat), motor thermal overload relay, and earth-leakage circuit breaker (30 mA sensitivity).

Sample Compatibility & Compliance

The HD-E702-1000B40/60 accommodates diverse sample configurations within its 1000 L internal volume (1000 mm × 1000 mm × 1000 mm). Standard load capacity supports up to 20 kg uniformly distributed across two adjustable SUS304 wire mesh shelves (30 mm pitch adjustment). A Φ100 mm calibrated access port—with removable silicone gasket and insulated plug—facilitates real-time signal feedthrough for embedded sensors or external power supply without compromising chamber integrity. The double-glazed, vacuum-insulated observation window incorporates resistive ITO film heating to prevent fogging during low-temperature/high-humidity cycles. All structural and operational parameters comply with GB/T 10589-2008 (chamber performance specification), GB/T 2423.3-2016 (damp heat test), and GJB 150.9A-2009 (MIL-STD-810H equivalent for military environmental engineering). Optional IQ/OQ documentation packages are available for GMP/GLP-regulated laboratories requiring 21 CFR Part 11-compliant audit trails.

Software & Data Management

Data acquisition and reporting are managed via the integrated UYI controller’s native logging engine, which records temperature, relative humidity, elapsed time, program segment ID, and alarm status at user-selectable intervals (1–600 seconds). Raw data is stored on a factory-installed 2 GB industrial-grade SD card with cyclic overwrite protection and tamper-evident timestamps. Export options include CSV via USB flash drive or direct serial transmission (RS232/RS485) to host PCs running Haida’s certified Windows-compatible software suite. This application supports real-time remote monitoring, multi-channel curve overlay, statistical process control (SPC) charting (X̄/R, Cp/Cpk), and automated PDF report generation—including header metadata (operator ID, test ID, calibration certificate reference, chamber serial number). All electronic records meet ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) for regulated quality systems.

FAQ

What standards does this chamber comply with for regulatory validation?
The HD-E702-1000B40/60 meets the physical performance requirements of GB/T 2423.1–2423.4, IEC 60068-2-1/-2/-3/-14, and MIL-STD-810G Method 502.6. Optional IQ/OQ protocols align with ISO/IEC 17025 and support FDA 21 CFR Part 11 compliance when paired with the full software package.
Can the chamber perform rapid temperature transitions between extremes?
Yes—it achieves ≥3 °C/min average heating rate from −60 °C to +150 °C and ≥1 °C/min cooling rate in the same range, enabled by its dual-stage refrigeration loop, oversized evaporator surface area, and optimized air velocity distribution.
Is remote monitoring and control supported?
Standard RS232/RS485 interfaces enable integration into centralized facility SCADA systems. Optional Ethernet/WiFi modules allow secure web-based access to live data, alarm history, and program management via TLS 1.2 encrypted connections.
How is humidity accuracy maintained during long-duration tests?
The chamber uses a dual-sensor validation approach: primary PT100-based dry-bulb/wet-bulb calculation supplemented by a secondary capacitive RH sensor (Vaisala HUMICAP® certified). Automatic dew-point compensation and periodic self-calibration routines ensure ≤±2% RH uncertainty over 1000-hour continuous operation.
What maintenance intervals are recommended for sustained accuracy?
Compressor oil and refrigerant charge verification every 24 months; desiccant filter replacement every 18 months; chamber door gasket inspection and cleaning quarterly; and annual NIST-traceable calibration of all temperature and humidity sensors using accredited third-party services.
