Overview
The APKJ AP-HX-5 Temperature and Humidity Controlled Environmental Test Chamber is an engineered precision instrument designed for rigorous physical property evaluation under tightly regulated thermal and hygroscopic conditions. It operates on a dual-control principle—simultaneous independent regulation of air temperature (via refrigeration/heating circuits) and relative humidity (via steam generation and desiccant-assisted dehumidification)—enabling stable, reproducible environmental simulation across extended test durations. The chamber conforms to core functional requirements outlined in ISO 16750-4 (Environmental Conditions for Electrical/Electronic Equipment), IEC 60068-2 series (Environmental Testing), and ASTM D4332 (Standard Practice for Conditioning Containers, Packages, or Packaging Components for Testing). Its architecture supports both steady-state (constant setpoint) and dynamic profile testing—including ramp-hold cycles, step changes, and multi-segment programmable sequences—making it suitable for material stability studies, accelerated aging, and quality assurance validation in R&D and production environments.
Key Features
- Robust stainless steel inner chamber with seamless welding and electrostatically coated cold-rolled steel outer casing; ergonomic curved design with anti-fingerprint matte-textured surface finish.
- Double-layer low-emissivity tempered glass observation window with integrated LED lighting and electrically heated anti-condensation film to maintain optical clarity during high-humidity operation.
- Dual-seal door system featuring silicone gasket compression and magnetic latching mechanism to minimize thermal and moisture leakage (leakage rate < 0.5% RH/h at 85% RH, 60°C).
- External water supply interface with auto-refill function and closed-loop condensate recovery circuit—reducing manual intervention and improving operational continuity.
- French Tecumseh (formerly “Tecumseh”) hermetic compressor with eco-friendly refrigerants (R23/R404A/R507 blend); optimized oil management system prevents lubricant accumulation in capillary tubes and evaporators.
- Korean TIME880 touchscreen controller with PID + SSR temperature/humidity regulation logic, DIN Class A PT-100 platinum resistance sensors (±0.15°C accuracy), and built-in self-calibration reference point adjustment.
- Programmable multi-step profiles: up to 999 hours per segment; slope-controlled ramping (0.1–10°C/min, 1–10% RH/min); real-time deviation correction via adaptive PID algorithm.
- Comprehensive safety architecture: independent over-temperature cut-off relay, audible/visual fault alerts, nine predefined error codes with diagnostic guidance, and mechanical locking casters with load-rated positioning screws.
Sample Compatibility & Compliance
The AP-HX-5 accommodates standard industrial test specimens including polymer films, electronic assemblies, pharmaceutical packaging, automotive interior materials, and composite laminates. Internal dimensions (W×D×H) support ISO-standard sample racks and optional shelf configurations. All control firmware and data logging functions comply with GLP/GMP documentation requirements: audit trail capability (optional OYO recorder interface), timestamped event logging, and password-protected parameter modification. Optional remote monitoring integration enables secure LAN/WAN access for centralized lab management systems—fully compatible with FDA 21 CFR Part 11-compliant electronic record architectures when paired with validated software platforms.
Software & Data Management
The TIME880 controller provides native USB export of time-stamped temperature/humidity logs (CSV format), real-time graphing of setpoint vs. actual curves, and configurable alarm thresholds. Optional RS-485/Modbus RTU output allows direct connection to SCADA systems or third-party LIMS. An auxiliary analog signal output (4–20 mA) is available for external chart recorders or PLC integration. Firmware supports user-defined calibration offset entry per sensor channel and retains configuration after power loss. Data integrity safeguards include cyclic redundancy check (CRC) on stored programs and automatic backup of last 10 executed profiles.
Applications
- Accelerated aging of elastomers and thermoplastics per ASTM D573 and ISO 188.

- Thermal cycling qualification of PCBAs under JEDEC J-STD-020 conditions.
- Moisture absorption kinetics analysis of hygroscopic ceramics and composites.
- Validation of storage conditions for active pharmaceutical ingredients (APIs) per ICH Q1A(R2).
- Environmental stress screening (ESS) of aerospace components per MIL-STD-810H Method 507.6.
FAQ
What standards does the AP-HX-5 meet for temperature and humidity uniformity?
Per internal verification protocol (based on ISO 16750-4 Annex B), temperature uniformity is ±0.8°C and humidity uniformity is ±3% RH across the working volume at 60°C / 95% RH steady state.
Can the chamber operate continuously for 30 days without maintenance?
Yes—designed for unattended long-term operation; recommended preventive maintenance interval is every 1,000 operating hours or annually, whichever occurs first.
Is the touchscreen interface available in English only, or bilingual?
Dual-language UI (English/Chinese) is standard; language selection is configurable during startup without firmware update.
Does the unit support validation documentation packages (IQ/OQ/PQ)?
Factory-supplied IQ/OQ templates are provided; PQ execution requires user-defined test protocols aligned with application-specific regulatory expectations.
What is the maximum allowable load weight on the internal shelves?
Each adjustable stainless steel shelf supports up to 35 kg uniformly distributed; total chamber payload capacity is 120 kg.
