HAIDA HD-E702-1000K Deep Blue Programmable Temperature and Humidity Chamber

Overview

The HAIDA HD-E702-1000K Deep Blue Programmable Temperature and Humidity Chamber is an engineered environmental simulation system designed for rigorous reliability testing of materials, components, and finished products under controlled thermal and hygrothermal stress conditions. It operates on the principle of precise thermodynamic regulation—employing dual-stage mechanical refrigeration, high-efficiency resistive heating, and isolation-type steam humidification—to replicate real-world climatic exposures defined in international test standards. This chamber supports both steady-state (constant) and dynamic (cycling) profiles across a wide operational envelope: −60 °C to +150 °C temperature range and 20–98 %RH humidity range. Its 1000 L internal volume (1000 mm × 1000 mm × 1000 mm) accommodates large-scale samples or multi-unit test configurations common in automotive electronics, aerospace composites, battery modules, and medical device packaging validation.

Key Features

• Robust Dual-Stage Refrigeration System: Equipped with two imported French Tecumseh hermetic compressors (2 × 3 HP), R404A/R23 eco-friendly refrigerants, and a binary cascade design enabling stable sub-zero operation down to −60 °C without performance degradation.
• Precision Climate Control Architecture: PID + SSR coordinated control algorithm with auto-tuning capability ensures rapid stabilization and minimal overshoot; temperature resolution of 0.01 °C and humidity resolution of 0.1 %RH are maintained via PT100 platinum resistance sensors.
• Thermally Optimized Construction: Inner chamber fabricated from 1.0 mm SUS304 stainless steel; outer enclosure finished with electrostatically applied deep-gray powder coating; 100 mm polyurethane foam + 100 mm high-density glass fiber insulation minimizes thermal bridging and energy loss.
• Fail-Safe Operational Integrity: Comprehensive protection suite includes compressor high-pressure/overload cut-off, phase-loss/reverse-phase detection, fan overheat shutdown, leakage current interruption, and programmable timed emergency stop—all compliant with IEC 61000-4 electromagnetic compatibility requirements.
• User-Centric Interface & Expandability: 7-inch full-color TFT touchscreen controller (Yudian brand) with bilingual (EN/CN) GUI, USB data export, RS232/RS485 communication ports, SD card logging (2 GB standard), and optional PC-based remote monitoring software integration.

Sample Compatibility & Compliance

The HD-E702-1000K accommodates diverse sample geometries and mass loads up to 20 kg per shelf (standard configuration: two adjustable stainless-steel mesh shelves). A Φ100 mm cable/port access hole with insulated plug enables external instrumentation interfacing without compromising chamber integrity. The double-layer vacuum-insulated observation window features integrated conductive film heating to prevent condensation during low-temperature/humidity transitions—ensuring uninterrupted visual monitoring. This chamber meets or exceeds key regulatory and industry-standard test protocols including GB/T 2423.1–2008 (cold), GB/T 2423.2–2008 (dry heat), GB/T 2423.3–2016 (damp heat, cyclic), IEC 60068-2-1/2/30, MIL-STD-810G Method 502.6/507.6, and GJB 150.3A–2009 / 150.4A–2009. Its construction and control architecture support GLP-compliant audit trails when paired with optional timestamped data logging and electronic signature modules.

Software & Data Management

The embedded Yudian controller supports up to 120 programmable test profiles, each comprising up to 99 segments with independent temperature/humidity setpoints, ramp rates, dwell times, and cycle counts (max 999 loops per segment). Real-time graphical display renders current profile progression alongside historical trend curves for both parameters. All operational data—including setpoints, actual values, alarm events, and system status—are logged at user-defined intervals (default: 1 min) onto internal SD storage. Export formats include CSV and PDF-compatible time-series plots suitable for regulatory submission. Optional Windows-compatible software provides advanced analysis tools: deviation mapping, statistical process control (SPC) charting, and automated report generation aligned with ISO/IEC 17025 documentation frameworks. Communication interfaces comply with Modbus RTU protocol for SCADA integration and support FDA 21 CFR Part 11–compliant electronic records when deployed with validated authentication and audit trail extensions.

Applications

• Accelerated aging studies of polymer encapsulants, conformal coatings, and PCB laminates under combined thermal-hygric stress.

• Environmental stress screening (ESS) of avionics hardware per DO-160G Section 4 (temperature) and Section 8 (humidity).
• Stability testing of pharmaceutical primary packaging per ICH Q1A(R2) guidelines requiring long-term and accelerated storage conditions.
• Corrosion susceptibility evaluation of coated metal substrates using cyclic corrosion testing (CCT) sequences per ASTM D6899 and ISO 11997-2.
• Pre-conditioning of optical sensors, MEMS devices, and precision metrology fixtures prior to calibration or functional verification.

FAQ

What is the maximum allowable sample weight per shelf?
The standard stainless-steel shelf supports uniform loading up to 20 kg. Load distribution must remain balanced to maintain airflow uniformity and thermal homogeneity.
Does the chamber support humidity control below 0 °C?
Humidity control is specified from 20 %RH to 98 %RH within the operational temperature band of −60 °C to +150 °C. Sub-zero humidity conditioning requires dehumidified air purge mode, not active vapor generation.
Can the controller store multiple test programs simultaneously?
Yes—the system stores up to 120 complete programs with 1200 total segments. Programs may be duplicated, linked, or scheduled with start/stop timers.
Is remote monitoring supported out of the box?
RS232/RS485 serial interfaces are standard; Ethernet or Wi-Fi connectivity requires optional gateway hardware and firmware upgrade.
What safety certifications does the unit carry?
The HD-E702-1000K conforms to CE marking requirements (EMC Directive 2014/30/EU, LVD Directive 2014/35/EU) and complies with GB 4793.1–2007 (safety of electrical equipment for measurement, control, and laboratory use). Third-party certification (e.g., UL, TÜV) is available upon request with additional validation testing.
