Overview
The APKJ AP-HX-B2 Programmable Temperature and Humidity Environmental Test Chamber is an industrial-grade environmental simulation system engineered for precise, repeatable, and long-term exposure testing of materials under controlled thermal and hygrothermal conditions. Utilizing a balanced temperature and humidity control (BTHC) architecture, the chamber dynamically regulates heating, cooling, humidification, and dehumidification to maintain setpoint stability—ensuring that net thermal and moisture input matches system losses. This closed-loop P.I.D.-driven SSR control eliminates overshoot and drift, enabling compliance with rigorous test protocols including IEC 60068-2-30 (cyclic damp heat), GB/T 2423.1 (cold), GB/T 2423.2 (dry heat), and GB/T 2423.34 (damp heat, cycling). Designed for accelerated aging, reliability validation, and qualification of polymers, elastomers, adhesives, coatings, and electronic assemblies, the AP-HX-B2 supports both steady-state and programmable multi-step profiles—including ramp-soak-cycling sequences with independent temperature and humidity scheduling.
Key Features
- Modular chamber construction with SUS#304 mirror-finish interior and corrosion-resistant outer cladding, ensuring long-term integrity in aggressive humidity environments.
- High-efficiency dual-stage refrigeration system featuring hermetically sealed Tecumseh compressors and environmentally compliant refrigerants, optimized for rapid thermal transitions and stable sub-zero operation down to –150 °C.
- Integrated steam-based humidification system with auto-fill water reservoir and anti-scaling design, delivering consistent RH control across the full 10–98 % RH range.
- TEMI-series touchscreen controller with intuitive graphical interface, real-time trend logging, USB data export, and user-defined profile storage (up to 100 programs, each with 99 segments).
- Comprehensive safety architecture: compressor thermal overload protection, heater dry-run interlock, chamber over-temperature cutoff, low-water level detection, and pressure-switch monitoring on refrigerant circuits.
- Standard features include dual-layer observation window with internal LED lighting, one 50 mm diameter cable port (left-side mounted), two adjustable sample racks, castor-mounted mobility, and integrated water tank with level indicator.
Sample Compatibility & Compliance
The AP-HX-B2 accommodates diverse specimen geometries—from small polymer coupons and PCB assemblies to automotive trim components and packaged consumer goods—within its configurable internal volumes (80 L to 1000 L standard; custom walk-in chambers up to 100 m³ available). Its uniformity performance (±2 °C temperature, ±2.5 % RH) meets ISO 16750-4, MIL-STD-810H Method 507.6, and ASTM D4332 requirements for conditioning prior to mechanical or electrical testing. The chamber’s validated thermal-hygric profiles support GLP-compliant documentation when paired with optional audit-trail-enabled software (21 CFR Part 11 ready upon configuration). All structural and control subsystems conform to CE marking directives (2014/30/EU EMC, 2014/35/EU LVD) and RoHS 2011/65/EU material restrictions.
Software & Data Management
The embedded TEMI controller provides local data acquisition at 1-second intervals, with on-device storage of up to 30 days of continuous timestamped readings (temperature, humidity, program stage, alarms). Optional RS485/RS232 or Ethernet interfaces enable integration into centralized lab management systems (LIMS) or SCADA platforms. APKJ-supplied PC software (Windows-compatible) supports remote monitoring, real-time graphing, automated report generation (PDF/CSV), and electronic signature capture for QA/QC workflows. For regulated environments, optional 21 CFR Part 11-compliant firmware adds role-based access control, electronic audit trails, and immutable data archiving—fully traceable to individual operators and test cycles.
Applications
- Evaluation of dimensional stability, color shift, and tensile property degradation in rubber compounds and thermoplastics exposed to tropical cargo hold conditions (e.g., 55 °C / 95 % RH for 168 h).
- Pre-conditioning of lithium-ion battery modules per UN 38.3 Section 4.4 (thermal cycling between –40 °C and +75 °C with humidity ramping).
- Validation of packaging barrier performance under cyclic humidity (e.g., 12 h at 25 °C/95 % RH followed by 12 h at 40 °C/10 % RH).
- Accelerated corrosion testing of coated metal substrates using combined thermal-hygric stress per ISO 9227.
- Stability assessment of pharmaceutical excipients and final dosage forms under ICH Q1A(R2) long-term and accelerated storage conditions.
FAQ
What is the minimum achievable temperature, and does it vary with humidity setpoint?
The AP-HX-B2 achieves –150 °C at 0 % RH; operational limits at elevated humidity levels are determined by dew point constraints and are specified in the chamber’s certified calibration report.
Can the controller store and replay complex multi-segment test profiles?
Yes—the TEMI HMI supports up to 100 programmable profiles, each containing 99 time-temperature-humidity segments with independent ramp rates, soak durations, and loop counts.
Is third-party calibration certification available?
APKJ provides NIST-traceable factory calibration with certificate (as option); field verification and ISO/IEC 17025-accredited calibration services are coordinated via authorized regional partners.
What maintenance intervals are recommended for the refrigeration system?
Compressor oil and filter replacement is advised every 18 months under continuous operation; annual inspection of humidifier electrodes, water lines, and condensate traps is required for optimal RH stability.
Does the system comply with FDA 21 CFR Part 11 for electronic records?
Out-of-the-box compliance requires optional Part 11 firmware upgrade, electronic signature module, and documented SOPs for user access management and audit trail review—fully implementable during installation commissioning.
