Apkji AP-HX80 Benchtop Temperature and Humidity Controlled Environmental Test Chamber

Overview

The Apkji AP-HX80 is a benchtop environmental test chamber engineered for precise, repeatable simulation of temperature and humidity stress conditions in laboratory and quality assurance environments. It operates on the principle of forced-air convection combined with precision PID-controlled refrigeration, heating, and humidification subsystems to maintain stable climatic profiles across defined test cycles. Designed for accelerated reliability testing and material stability evaluation, the chamber supports static and dynamic environmental profiles—including constant, cycling, and ramp-hold modes—per widely adopted international standards for environmental stress screening. Its compact footprint and modular architecture make it suitable for integration into QC labs, R&D facilities, and small-batch validation workflows where space efficiency and regulatory traceability are critical.

Key Features

• Stainless steel construction (SUS304) with sandblasted finish ensures corrosion resistance, cleanability, and long-term dimensional stability under thermal cycling.
• High-efficiency insulation using HCFC-free polyurethane foam minimizes thermal leakage and improves energy performance across extreme operating ranges (−70°C to +100°C).
• Dual-stage compressor configuration (air-water cooled) enables rapid cooling down to −70°C with controlled ramp rates (1.0–3.0°C/min heating; ~4.0°C/min cooling), while single-stage operation suffices for milder low-temperature applications (≥−20°C).
• Programmable touchscreen controller (TEMI or OYO) supports multi-segment profile programming, slope/ramp control, real-time data logging, and alarm-triggered event capture.
• Integrated humidity generation system with auto-refill capability, external water supply interface, and condensate recovery reduces manual intervention and maintains consistent RH accuracy (±3% RH deviation).
• Double-gasketed observation window with anti-fog heater and high-luminance PL lamp enables continuous visual monitoring without thermal disturbance or condensation interference.
• Comprehensive safety architecture includes over-temperature/over-humidity cut-offs, refrigerant high/low pressure protection, compressor overload relay, and fuse-based circuit isolation.

Sample Compatibility & Compliance

The AP-HX80 accommodates diverse sample geometries and material classes—including PCB assemblies, polymer films, pharmaceutical packaging, elastomeric seals, optical components, and biomedical devices—within its 80 L internal volume (40 × 50 × 40 cm). Its design conforms to structural and performance requirements outlined in GB/T 2423 series (equivalent to IEC 60068-2), GJB 150, and ISO 16750-4 for environmental stress qualification. While not certified for GLP/GMP production environments by default, the chamber’s programmable controller supports audit-ready data export (CSV/TXT), timestamped event logs, and user-access-level configuration restrictions—facilitating alignment with FDA 21 CFR Part 11 documentation practices when paired with validated SOPs and electronic signature protocols.

Software & Data Management

The TEMI or OYO controller provides native support for up to 99 programmable test segments, each configurable with independent setpoints, dwell times, ramp rates, and humidity coupling logic. Real-time display shows both measured and target values for temperature and relative humidity, alongside elapsed time and cycle progress. Data can be exported via USB to external storage for post-test analysis in Excel or statistical process control (SPC) platforms. Optional analog output (4–20 mA) and RS485 Modbus RTU interfaces enable integration with centralized building management systems (BMS) or SCADA networks. Firmware updates are performed locally via SD card, ensuring version control and traceability during equipment lifecycle management.

Applications

• Accelerated aging of packaging materials under combined thermal and hygroscopic stress per ASTM D4332 and ISO 2233.
• Functional verification of electronic assemblies following JEDEC JESD22-A104 (temperature cycling) and JESD22-A101 (damp heat).
• Stability assessment of active pharmaceutical ingredients (APIs) and final drug products per ICH Q1A(R2) guidelines.
• Validation of adhesive bond strength retention across humidity gradients (e.g., ASTM D1002, ISO 4587).
• Environmental stress screening (ESS) of automotive ECUs per SAE J1211 and ISO 16750-4.
• Calibration reference chamber for secondary humidity sensors and hygrometer verification (traceable to NIST-equivalent national standards).

FAQ

What is the standard temperature and humidity uniformity specification for the AP-HX80?
Uniformity is specified as ±1.0°C (temperature) and ±3.0% RH (humidity) across the working volume under steady-state conditions, verified per GB/T 10586 and IEC 60068-3-5.
Can the chamber operate continuously at −70°C with full humidity control?
No—humidification is disabled below 0°C to prevent ice formation in the steam generator and distribution ducts; sub-zero operation is dry-cold only.
Is remote monitoring supported out-of-the-box?
Standard configuration includes local USB data export; Ethernet or Wi-Fi connectivity requires optional communication module upgrade and third-party middleware integration.
Does the unit include calibration certificates upon delivery?
Factory calibration reports (temperature/humidity sensor offsets) are provided; ISO/IEC 17025-accredited calibration must be arranged separately through authorized metrology service providers.
What maintenance intervals are recommended for compressor oil and refrigerant?
Tecumseh compressors are sealed-for-life; no scheduled oil changes are required. Refrigerant integrity checks should occur annually or after 2,000 operational hours, whichever comes first.
