Micono GDS-010 High-Low Temperature & Humidity Environmental Test Chamber

Overview

The Micono GDS-010 High-Low Temperature & Humidity Environmental Test Chamber is an engineered solution for accelerated environmental stress testing of industrial components and materials under controlled thermal and hygrometric conditions. Designed in accordance with fundamental principles of thermodynamic equilibrium and psychrometric control, the chamber employs a balanced heating–cooling–humidification system to precisely maintain setpoint temperature and relative humidity (RH) across its working volume. Its operational envelope spans from −60 °C to 100 °C (with model-specific low-temperature variants), and supports both steady-state and cyclic profiles—including temperature-only, humidity-only, and combined temperature–humidity cycling per IEC 60068-2 and GB/T 2423 series standards. The chamber’s structural integrity, thermal insulation performance, and closed-loop control architecture ensure high reproducibility and long-term stability—critical for qualification testing in electronics, automotive, aerospace, and academic R&D environments.

Key Features

• Internally constructed from electropolished SUS304 stainless steel; outer casing available in either brushed SUS304 or A3 steel with epoxy powder coating for corrosion resistance.
• High-sealing door gasket made of dual-durometer silicone rubber, rated for continuous operation between −70 °C and 150 °C without hardening or cracking.
• Equilibrium-based temperature–humidity control strategy eliminates overshoot and minimizes transient drift during ramp-and-soak cycles.
• Intelligent refrigeration circuit selection automatically engages optimal compressor staging based on real-time setpoint and load conditions—reducing energy consumption and extending component life.
• Shallow-tray surface evaporation humidification system ensures uniform RH distribution and avoids condensate pooling or localized saturation.
• Integrated 250 × 300 mm double-glazed observation window with anti-fog heating element and IP65-rated LED interior lighting for unobstructed visual monitoring.
• Modular refrigeration architecture supports field-upgradable cascade configuration for extended low-temperature capability (−60 °C).

Sample Compatibility & Compliance

The GDS-010 accommodates diverse sample geometries up to 400 × 500 × 500 mm (W×H×D), with load capacity optimized for electronic assemblies, PCBs, battery modules, polymer housings, and mechanical subassemblies. It fully complies with national and international environmental testing standards, including GB/T 2423.1 (cold test), GB/T 2423.2 (dry heat), GB/T 2423.3 (constant damp heat), GB/T 2423.4 (cyclic damp heat), GB/T 10592 (high–low temperature chamber specifications), and GB/T 10586 (damp heat chamber specifications). While not pre-certified to ISO/IEC 17025, the chamber’s traceable PT100 sensors, documented calibration intervals, and audit-ready controller logs support GLP-compliant validation protocols when integrated into laboratory quality systems.

Software & Data Management

Standard configuration includes a Fuji Electric PXR series PID controller with 16-segment programmable ramp–soak capability, real-time trend logging (≥30 days at 1-min intervals), and USB data export. Optional upgrade to a wide-format touchscreen programmable controller (imported OEM unit) provides Ethernet connectivity, remote supervision via Modbus TCP, password-protected parameter locking, and built-in audit trail functionality compliant with FDA 21 CFR Part 11 requirements for electronic records and signatures. All controllers generate timestamped CSV log files containing chamber temperature, humidity, setpoint, and alarm status—enabling seamless integration with LIMS or MES platforms.

Applications

• Qualification of automotive ECUs, connectors, and sensor housings per ISO 16750-4 (climate stress).
• Accelerated aging studies of lithium-ion battery cells under thermal–hygric stress (UN 38.3 thermal cycling protocol).
• Reliability screening of printed circuit boards (PCBs) and conformal coatings per IPC-9701A.
• Material compatibility testing of adhesives, elastomers, and encapsulants under sustained high-humidity exposure.
• Validation of packaging integrity for sterile medical devices under ISO 11607-1 climatic conditioning.
• Graduate-level materials science research involving phase transition behavior of polymers and composites.

FAQ

What temperature and humidity ranges does the GDS-010 support?

The standard operating range is −20 °C to 100 °C with 20–98% RH. Variant models extend the low-temperature limit to −40 °C or −60 °C via cascade refrigeration.

Is the chamber suitable for continuous 24/7 operation?

Yes—designed for Class II industrial duty cycle with reinforced compressor mounting, redundant safety interlocks, and thermal overload protection on all critical subsystems.

Can the controller be validated for regulated environments?

The optional touchscreen controller supports IQ/OQ documentation templates, electronic signature capture, and audit trail generation aligned with FDA 21 CFR Part 11 and EU Annex 11 expectations.

What maintenance is required to sustain accuracy?

Recommended quarterly verification of PT100 sensor calibration against NIST-traceable reference, biannual inspection of evaporator fins and condensate drain lines, and annual refrigerant pressure and oil level assessment by certified technicians.

Does Micono offer custom chamber configurations?

Yes—non-standard internal dimensions, specialized ports (e.g., multi-channel feedthroughs), explosion-proof enclosures, or integrated vibration tables can be engineered upon technical review and formal specification submission.
