Micono HS-050 Constant Temperature & Humidity Test Chamber

Overview

The Micono HS-050 Constant Temperature & Humidity Test Chamber is an engineered environmental simulation system designed for precise, long-duration exposure testing under stabilized thermal and hygroscopic conditions. Based on the fundamental principles of convective heat transfer and controlled vapor-phase equilibrium, the chamber maintains rigorously defined temperature and relative humidity setpoints to replicate tropical or high-humidity operational environments. It complies with key international and national standards including GB/T 2423.3 (equivalent to IEC 60068-2-78) for steady-state damp heat testing and GB/T 10586–2019 (revised from GB 10586–89) for climatic test chamber performance requirements. The system is purpose-built for evaluating material stability, electrical insulation integrity, corrosion resistance, and functional reliability of components subjected to prolonged exposure at elevated humidity and moderate temperature—critical for qualification in electronics, automotive ECUs, aerospace avionics, and defense-grade instrumentation.

Key Features

• Stainless steel interior chamber (SUS304) and powder-coated A3 steel outer casing ensure corrosion resistance and structural durability.
• High-precision Fuji Electric PID temperature/humidity controller with real-time digital display and auto-tuning capability for stable setpoint maintenance.
• Shallow-tray surface evaporation humidification system enables uniform RH distribution and minimizes water carryover or condensation risk.
• Imported hermetic compressor (Embraco or equivalent) paired with finned-tube multi-stage evaporator and air-cooled condenser for consistent cooling performance across operating ranges.
• Anti-condensation double-layer observation window (250 × 300 mm), LED interior lighting, and Ø50 mm cable/port access port support real-time monitoring and external signal interfacing.
• Comprehensive safety architecture: over-temperature cutoff, dry-run protection for humidifier, refrigerant high-pressure safeguard, leakage current interruption, and fast-acting thermal fusing.

Sample Compatibility & Compliance

The HS-050 accommodates a broad range of sample geometries up to 700 × 800 × 900 mm (W × D × H) internal volume, supporting PCB assemblies, sensor modules, polymer housings, battery packs, and sealed enclosures. Its validated performance meets traceable compliance requirements for GLP-regulated laboratories and pre-compliance screening per ISO/IEC 17025 quality systems. While not certified to UL or IEC 60068-2-30 (cyclic damp heat), its steady-state operation aligns with ASTM D4332 (conditioning of plastics) and MIL-STD-810G Method 507.5 (humid heat, steady-state) when configured per user-defined test protocols. All control parameters—including ramp rates, dwell times, and humidity stabilization thresholds—are fully configurable and auditable via onboard event logging.

Software & Data Management

The Fuji PID controller supports RS-485 Modbus RTU communication for integration into centralized lab management platforms (e.g., LabVIEW, SCADA, or custom MES). Optional data logging modules record temperature and RH values at user-selectable intervals (1 s to 60 min), generating timestamped CSV files compatible with statistical process control (SPC) software. Audit trails include operator ID, parameter changes, alarm events, and calibration timestamps—supporting basic FDA 21 CFR Part 11 readiness when deployed with password-protected user roles and electronic signature workflows. Firmware updates are performed via USB interface; no cloud dependency or proprietary cloud service is required.

Applications

• Qualification testing of printed circuit boards (PCBs) and conformal coatings per IPC-J-STD-001 and IPC-A-610.
• Accelerated aging studies of elastomeric seals, adhesives, and encapsulation resins used in outdoor-rated electronics.
• Pre-screening of lithium-ion battery modules prior to thermal runaway evaluation under humid ambient conditions.
• Verification of ingress protection (IP) ratings for enclosures exposed to sustained high-RH environments.
• Material compatibility assessment for medical device housings subject to ISO 10993-12 extractables testing protocols.

FAQ

What is the standard temperature and humidity operating range for the HS-050 model?

The HS-050 operates within 0–100°C and 45–98% RH (DHS configuration), with typical test profiles conducted between 40°C/93% RH and 60°C/95% RH per GB/T 2423.3.

Does the chamber support programmable ramp-and-soak profiles?

No—the HS-050 is engineered exclusively for constant (steady-state) temperature and humidity conditions. For dynamic cycling, consider the Micono TC series with dedicated profile controllers.

Is third-party calibration certification available?

Yes—NIST-traceable calibration certificates (temperature and humidity sensors) can be provided upon request, compliant with ISO/IEC 17025 requirements.

What maintenance is required to sustain long-term accuracy?

Quarterly inspection of humidifier tray cleanliness, annual verification of PT100 sensor drift, and biannual refrigerant pressure checks are recommended. Full preventive maintenance kits are available.

Can the unit be integrated into a facility’s building management system (BMS)?

Yes—via optional analog 4–20 mA output modules or Modbus TCP gateway adapters for seamless BMS interoperability.
