Apkji 100AP-HX Desktop Temperature and Humidity Controlled Environmental Test Chamber

Overview

The Apkji 100AP-HX is a benchtop temperature and humidity controlled environmental test chamber engineered for precision stability, repeatable conditioning, and long-term reliability in laboratory and quality assurance environments. It operates on a dual-loop refrigeration principle—employing either single-stage or cascade (two-stage) compression cycles—to achieve accurate thermal and hygrometric control across defined operational ranges. The system integrates a high-efficiency air circulation architecture with multi-blade centrifugal fans, ensuring uniform thermal distribution and minimizing spatial gradients in both temperature and relative humidity. Designed for compliance-driven applications—including product validation, material aging studies, and component stress testing—the 100AP-HX delivers traceable environmental simulation under tightly regulated conditions. Its core architecture supports programmable cycling, real-time monitoring, and remote supervisory control via industry-standard communication protocols.

Key Features

• Benchtop footprint optimized for space-constrained laboratories without compromising internal volume scalability (standard options: 50 L to 1000 L; custom volumes available)
• AP-900 intelligent touchscreen controller with intuitive graphical interface, programmable step-and-ramp profiles, and built-in data logging capability
• Multi-point temperature and humidity uniformity maintained within ≤±2.0°C (temp) and ≤±2.5% RH (humidity), validated per IEC 60068-3-5
• Cascade refrigeration system utilizing environmentally compliant refrigerants (R404A/R23 or R134a/R404A), meeting U.S. EPA SNAP and EU F-Gas Regulation requirements through 2030+
• French Tecumseh “Iron Warrior” or German Bitzer semi-hermetic compressors for stable low-temperature performance down to –70°C (model-dependent configuration)
• LAN and RS-232/RS-485 interfaces enabling integration into centralized lab management systems, SCADA platforms, or LIMS infrastructure
• Comprehensive safety architecture including over-temperature cutoff, compressor high-pressure shutdown, sensor fault detection, and automatic power isolation

Sample Compatibility & Compliance

The 100AP-HX accommodates a broad spectrum of non-hazardous solid, packaged, and electronic samples—including PCB assemblies, polymer specimens, pharmaceutical packaging, and consumer electronics—within its insulated stainless-steel interior. Its design conforms to multiple international environmental test standards, including GB/T 10589–1989 (Low-Temperature Test Chambers), GB/T 10592–1989 (Climatic Test Chambers), GB/T 2423.1–2008 (Cold Testing), GB/T 2423.4–2012 (Damp Heat, Cyclic), and MIL-STD-810G Method 502.2 (Low Temperature) and Method 507.2 (Humidity). While not certified for explosion-proof or intrinsically safe operation, the chamber meets general-purpose industrial safety requirements per GB 4793.1 and IEC 61010-1.

Software & Data Management

The AP-900 controller firmware supports full-cycle program definition (up to 99 segments, 999 steps), real-time parameter display, and timestamped event logging. Data export is enabled via USB mass storage or network transfer in CSV format. Optional software packages provide PC-based remote supervision, alarm notification via email/SNMP traps, and audit-trail generation compliant with GLP and GMP documentation requirements. All controller operations—including parameter modification, profile execution, and manual override—are logged with user ID, timestamp, and action type, satisfying traceability mandates under FDA 21 CFR Part 11 when configured with appropriate access controls and electronic signature modules.

Applications

• Accelerated aging of polymers, adhesives, and elastomers under controlled thermal-hygrometric stress
• Environmental qualification testing of printed circuit boards and embedded electronics per IPC-9701
• Stability testing of medical device packaging per ISO 11607-1
• Validation of HVAC filter media performance under variable humidity loading
• Calibration support for hygrometers and thermistors using NIST-traceable reference sensors
• Material compatibility assessment for lithium-ion battery enclosures exposed to humidified cold soak conditions

FAQ

What is the lowest achievable temperature for the 100AP-HX series?
Standard configurations support –20°C, –40°C, and –70°C variants; the –70°C model employs a two-stage cascade refrigeration system with R23/R404A refrigerant pairing.
Does the chamber support automated humidity ramping during temperature cycling?
Yes—the AP-900 controller enables synchronized humidity and temperature profile programming, including dwell, ramp, and hold sequences with independent setpoint resolution.
Is the unit compatible with third-party LIMS or MES platforms?
It provides native Modbus RTU/TCP and ASCII protocol support via RS-485 and Ethernet ports, facilitating direct integration with most enterprise laboratory informatics systems.
What maintenance intervals are recommended for the refrigeration system?
Compressor oil and filter-drier replacement is advised every 24 months under continuous operation; annual verification of refrigerant charge and sensor calibration is recommended for ISO/IEC 17025-compliant labs.
Can the chamber be used for salt spray or corrosive gas testing?
No—this model lacks corrosion-resistant internal cladding or exhaust scrubbing; it is intended exclusively for dry/wet thermal-humidity simulation.
