Apkji AP-DG-80A Touchscreen Temperature and Humidity Controlled Environmental Test Chamber

Overview

The Apkji AP-DG-80A Touchscreen Temperature and Humidity Controlled Environmental Test Chamber is an engineered solution for accelerated environmental stress testing of materials and components under precisely regulated thermal and hygrothermal conditions. Based on the BT(H)C (Balance Temperature and Humidity Control) principle, the chamber maintains stable setpoints through simultaneous modulation of heating, refrigeration, and steam humidification subsystems—ensuring dynamic equilibrium without overshoot or prolonged stabilization delays. Its robust architecture integrates a French Tecumseh (or equivalent-tier) hermetic rotary compressor, Ni-Cr alloy heating elements, centrifugal forced-air circulation, and high-efficiency polyurethane/glass fiber insulation—delivering consistent thermal performance across the full operating envelope of -40°C to +150°C and 20–98% RH. Designed for laboratory and industrial QA/QC environments, the AP-DG-80A supports both steady-state (fixed-value) and complex multi-step cycling protocols, making it suitable for evaluating long-term reliability, material degradation, condensation resistance, and thermal expansion behavior in accordance with internationally recognized test standards.

Key Features

• 5.7-inch high-resolution TFT color touchscreen interface (Q8-902 controller) with bilingual (English/Chinese) menu navigation and intuitive drag-and-drop programming
• BT(H)C balanced control algorithm ensuring minimal temperature/humidity overshoot and rapid recovery after door opening or load changes
• Dual-wall construction: exterior cold-rolled galvanized steel with epoxy powder coating; interior SUS304 stainless steel for corrosion resistance and cleanability
• Programmable test sequences: up to 269 stored profiles, each supporting 50 steps and 3200 nested cycles—enabling replication of real-world environmental exposure histories (e.g., diurnal cycling, seasonal transitions)
• Integrated data logging with battery-backed RAM: records timestamped temperature, humidity, and alarm events for up to 90 days at 1-minute intervals
• Comprehensive safety system including over-temperature/over-humidity cut-off, compressor high-pressure protection, phase failure detection, and timed auto-shutdown
• Optional RS-485, Ethernet, and mobile communication modules support remote monitoring and centralized fleet management across up to 254 units (cable run ≤1200 m)

Sample Compatibility & Compliance

The AP-DG-80A accommodates a broad spectrum of physical specimens—from printed circuit boards (PCBs), LED modules, and automotive ECUs to polymer composites, aerospace fasteners, and pharmaceutical packaging materials. Internal dimensions (W×H×D: 50×75×60 cm) provide sufficient volume for representative batch testing while maintaining airflow uniformity per IEC 60068-3-5. The chamber meets structural and operational requirements for compliance-driven testing workflows, including ASTM D4332 (conditioning of plastics), ISO 4892-2 (plastics—UV exposure), IEC 60068-2-1 (cold), -2 (dry heat), -14 (change of temperature), and -30 (damp heat, cyclic). Its control system architecture supports audit-ready operation when configured with optional 21 CFR Part 11-compliant software extensions, enabling electronic signatures, user access levels, and immutable audit trails for GLP/GMP-regulated laboratories.

Software & Data Management

The embedded Q8-902 controller provides native data visualization—including real-time trend graphs, deviation alarms, and cycle progress tracking—without external PC dependency. For advanced analysis, optional Windows-based PC software (compatible with Windows 10/11) enables export of CSV-formatted datasets, automated report generation (PDF/Excel), and comparative overlay of multiple test runs. All logged data includes ISO 8601 timestamps, operator ID, and event annotations (e.g., “door opened”, “program paused”). Remote access functionality permits secure web-based supervision via encrypted HTTP(S) or Modbus TCP, facilitating integration into enterprise LIMS or MES platforms. Firmware updates are delivered via USB or network push—ensuring continuous alignment with evolving calibration and cybersecurity best practices.

Applications

• Electronics reliability validation: thermal cycling of PCBAs, solder joint fatigue assessment, and moisture sensitivity level (MSL) pre-conditioning per J-STD-020
• Automotive component qualification: climate endurance testing of sensors, displays, and infotainment systems per ISO 16750-4
• LED lighting performance evaluation: lumen maintenance and color shift analysis under combined thermal-hygric stress
• Polymer and composite aging studies: hydrolytic degradation kinetics, dimensional stability, and creep behavior
• Academic research in material science: phase transition mapping, glass transition temperature (Tg) estimation, and diffusion coefficient modeling
• Pharmaceutical packaging integrity: barrier property verification under accelerated humidity conditions (e.g., 40°C/75% RH)

FAQ

What is the standard warranty coverage for the AP-DG-80A?

Apkji provides a 12-month limited warranty covering parts and labor for defects in materials or workmanship under normal use. Extended service plans and preventive maintenance contracts are available upon request.
Can the chamber be validated for IQ/OQ/PQ protocols?

Yes—the AP-DG-80A is supplied with factory calibration certificates traceable to NIST standards. Optional validation support packages include as-found/as-left reports, sensor mapping data, and protocol templates aligned with ISO 17025 and Annex 15.
Is remote firmware update capability included?

Firmware updates require manual initiation via USB drive or network upload; automatic over-the-air updates are not enabled by default for security and regulatory compliance reasons.
Does the controller support custom alarm logic or user-defined pass/fail criteria?

The base Q8-902 controller supports threshold-based alarms and relay outputs; advanced conditional logic (e.g., “if T > 85°C for >5 min, then trigger shutdown”) requires optional scripting module licensing.
What power supply configurations are supported?

Standard configuration: AC 220 V ±10%, 50 Hz, single-phase + PE. Optional three-phase 380 V ±10%, 50 Hz, four-wire + PE configuration is available for higher-capacity models or facility grid compatibility.
