Overview
The Apkji AP-HX-80A Temperature and Humidity Controlled Environmental Test Chamber is an engineered precision system designed for accelerated environmental stress testing of electronic components, electrical assemblies, instrumentation, plastics, and other industrial materials. It operates on the principle of forced-air convection with dual independent control loops—thermal (via electric heating and refrigerant-based cooling) and hygral (via steam humidification and mechanical dehumidification)—to maintain stable, programmable conditions across defined temperature and relative humidity (RH) ranges. The chamber supports both steady-state and dynamic cycling profiles, enabling simulation of real-world storage, transportation, and operational environments per internationally recognized test standards. Its 408 L internal volume provides sufficient workspace for medium-scale test specimens while maintaining uniform thermal-hygrometric distribution in accordance with IEC 60068-3-5 and ISO 16750-4 methodology.
Key Features
- Balance Temperature & Humidity Control (BTHC) system utilizing PID-controlled SSR actuators to dynamically match heating/humidifying output with chamber thermal and moisture losses—ensuring long-term stability and minimal overshoot.
- Full capillary tube refrigeration circuit with automatic capacity modulation, eliminating reliance on thermostatic expansion valves; delivers superior temperature ramping linearity, faster stabilization, and improved energy efficiency compared to conventional systems.
- High-fidelity stainless-steel interior with seamless welding, corrosion-resistant exterior housing, and ergonomic access door with double-layer insulated glass viewport and safety interlock.
- Integrated multi-point sensor array—including PT100 temperature sensors and capacitive RH transducers—calibrated traceably to NIST standards, ensuring measurement repeatability within ±0.3°C and ±2% RH (20–95% RH range).
- Comprehensive safety architecture: overtemperature cut-off, dry-run protection, low-water-level alarm, compressor high-pressure/overheat/overcurrent monitoring, emergency stop button, and non-fuse circuit breakers compliant with IEC 61000-4-5 surge immunity requirements.
Sample Compatibility & Compliance
The AP-HX-80A accommodates a broad spectrum of physical sample forms—including PCBs, enclosures, connectors, polymer housings, battery modules, and optical components—without requiring modification to standard mounting fixtures. It meets or exceeds technical specifications outlined in GB/T 10586–2014 (Humidity Testing Equipment), GB/T 10589–2008 (Low-Temperature Testing Equipment), and GB/T 10592–2008 (Climatic Testing Equipment). Additionally, it supports execution of test procedures aligned with MIL-STD-810H Method 502.5 (Cold), Method 507.5 (Humidity), Method 506.6 (Rain), and Method 511.6 (Salt Fog); IEC 60068-2-1 (Cold), -2-2 (Dry Heat), -2-30 (Damp Heat Cycle); and GJB 150.9A–2009 (Temperature-Humidity). All control logic and data logging comply with GLP/GMP documentation integrity principles and support audit-ready configuration for FDA 21 CFR Part 11–governed laboratories.
Software & Data Management
Equipped with Apkji’s proprietary WinTest Pro v4.2 control software, the chamber enables full-cycle programming—including ramp-soak-step sequences, profile looping, and conditional branching—with up to 100 user-defined programs stored locally. Real-time monitoring includes graphical trend display of temperature, RH, and system status parameters (compressor duty cycle, heater output, humidifier current). Data export is supported in CSV and PDF formats with embedded timestamps, operator ID, and calibration metadata. Optional Ethernet/IP interface allows integration into centralized MES or LIMS platforms via Modbus TCP or OPC UA protocols. Audit trail functionality logs all parameter changes, user logins, and alarm events with immutable timestamps—fully traceable for regulatory review.
Applications
This environmental chamber serves critical roles in product development validation, incoming quality inspection, and reliability assurance workflows. Typical use cases include: accelerated life testing of automotive ECUs under combined thermal-hygral stress; qualification of medical device enclosures per ISO 14971 risk management protocols; evaluation of conformal coating durability on printed circuit boards; verification of packaging material barrier performance under tropical climatic conditions; and screening of lithium-ion battery thermal runaway thresholds at elevated humidity levels. It is routinely deployed in R&D labs, Tier-1 supplier QA departments, third-party certification bodies (e.g., SGS, TÜV, UL), and contract manufacturing facilities operating under IATF 16949 or ISO 9001 quality management systems.
FAQ
What temperature and humidity ranges does the AP-HX-80A support?
Standard configuration covers –40°C to +150°C and 20% to 98% RH. Custom configurations are available upon request for extended ranges, including sub-zero humidity operation down to 10% RH at low temperatures.
Is the chamber compatible with remote monitoring and automation systems?
Yes—equipped with RS485 and optional Ethernet interfaces supporting Modbus RTU/TCP and OPC UA for integration into SCADA, MES, or custom LabVIEW-based control environments.
How is temperature and humidity uniformity validated inside the working chamber?
Uniformity is verified per GB/T 2423.34 and IEC 60068-3-5 using nine calibrated PT100 and RH sensors placed at specified locations (corners and center) across the usable volume, with acceptance criteria of ±1.5°C and ±3% RH.
Does the system include calibration documentation and traceability?
Each unit ships with factory calibration certificates for all primary sensors, traceable to national metrology institutes (NIM, CNAS-accredited), and includes instructions for user-performed periodic verification using external reference standards.
Can non-standard chamber dimensions or mounting configurations be accommodated?
Yes—Apkji offers OEM engineering services for bespoke chamber geometries, customized shelf layouts, cable/port penetrations, and integration with adjacent equipment such as vibration tables or power supplies.
