Overview
The Micono DHS-010 Low-Temperature Constant Humidity & Thermal Test Chamber is an engineered environmental simulation system designed to replicate controlled low-temperature, high-humidity conditions for rigorous reliability assessment of materials and components. Based on the principle of forced-air convection with precision PID-regulated thermal and hygric control, the chamber maintains stable setpoints across its operational range—enabling standardized evaluation of product behavior under sustained damp heat stress. It is specifically configured to meet the physical test requirements defined in GB/T 2423.3 (equivalent to IEC 60068-2-3) for “Test Ca: Damp Heat, Steady State” and complies with GB/T 10586–2006 (formerly GB 10586–89), the national standard governing technical specifications for temperature-humidity test chambers in China. The unit supports validation protocols aligned with industrial quality assurance frameworks including ISO 9001, IATF 16949 (for automotive suppliers), and GLP-compliant environmental testing workflows.
Key Features
- Stainless steel interior chamber (SUS304) and A3 steel exterior with epoxy powder coating for corrosion resistance and structural integrity
- High-precision Fuji Electric PID controller with dual-channel digital display for independent temperature and humidity regulation
- Shallow-tray surface evaporation humidification system ensuring uniform RH distribution and minimizing condensation risk
- Imported hermetic compressor with finned-tube evaporator and multi-stage refrigeration circuit for stable sub-zero cooling performance
- Anti-condensation double-layer observation window (250 × 300 mm), LED interior lighting, and 50 mm diameter cable/port access opening
- Integrated safety architecture: over-temperature cutoff, dry-run protection for humidifier, compressor high-pressure interlock, leakage current protection, and fast-blow fuse
- Low-noise centrifugal blower with extended-shaft design and stainless steel impeller for consistent air circulation and thermal homogeneity
Sample Compatibility & Compliance
The DHS-010 accommodates a broad spectrum of non-hazardous solid specimens—including printed circuit boards (PCBs), electronic enclosures, polymer housings, aerospace fasteners, automotive sensors, and medical device packaging—within its 400 × 500 × 500 mm working volume. Its temperature range (0–100 °C) and humidity range (45–98 %RH) support both accelerated aging studies and long-term stability verification per industry-standard test plans. All operational parameters are traceable to NIST-traceable reference standards via calibrated PT100 platinum resistance sensors. The chamber satisfies mandatory compliance checkpoints for CE-marked equipment (EN 61000-6-2/6-4), and its control architecture supports audit-ready documentation when integrated into FDA 21 CFR Part 11–compliant laboratory information management systems (LIMS) via optional RS485/Modbus RTU interface.
Software & Data Management
While the base configuration utilizes Fuji’s standalone PID controller with local data logging (up to 100 program steps, 99 segments), optional PC-based software enables remote monitoring, real-time graphing, automated report generation (PDF/CSV), and electronic signature capture. Data logs include timestamped temperature, relative humidity, setpoint deviation, alarm events, and runtime diagnostics—structured to fulfill GLP/GMP record retention requirements (minimum 3-year archival). Audit trails record user logins, parameter modifications, and calibration interventions, supporting regulatory readiness for ISO/IEC 17025-accredited laboratories.
Applications
- Electronics: Evaluation of solder joint integrity, conformal coating performance, and moisture-induced failure mechanisms (e.g., popcorning, delamination)
- Automotive: Validation of infotainment modules, battery management systems, and connector assemblies per SAE J2241 or VW 80101
- Aerospace: Environmental screening of avionics housings and composite fasteners under MIL-STD-810H Method 507.6
- Academic Research: Controlled degradation studies of biodegradable polymers and pharmaceutical excipients under elevated humidity
- Quality Assurance: In-process verification of sealing effectiveness for IP67-rated enclosures and medical device sterilization packaging
FAQ
What is the lowest achievable temperature with humidity active?
The DHS-010 achieves a minimum operating temperature of 0 °C while maintaining humidity ≥45 %RH; sub-zero operation requires dehumidification mode only.
Is the chamber suitable for continuous 24/7 operation?
Yes—designed for unattended long-duration testing with redundant thermal protection and compressor duty-cycle management.
Can the unit be customized for non-standard chamber dimensions or extended temperature ranges?
Custom engineering is available for OEM integration, including larger volumes (DHS-025 to DHS-100 variants), extended low-temperature capability (–20 °C or –40 °C), and specialized sensor ports.
Does the system support third-party calibration certification?
Factory calibration certificates (traceable to CNAS-accredited labs) are provided; on-site ISO/IEC 17025 calibration services can be arranged upon request.
What power supply options are supported?
Standard configuration: 220 VAC ±10 %, 50 Hz single-phase; optional 380 VAC ±10 %, 50 Hz three-phase four-wire supply available for higher-capacity models.
