Apkji AP-HX-80C Temperature and Humidity Controlled Environmental Test Chamber

Overview

The Apkji AP-HX-80C Temperature and Humidity Controlled Environmental Test Chamber is an engineered solution for precise, repeatable simulation of climatic stress conditions during product development, qualification, and quality assurance. Designed in accordance with internationally recognized environmental testing standards—including IEC 60068-2, MIL-STD-810D, and GB/T 10592—it employs a balanced heating, cooling, and humidification control architecture (BTHC) to maintain stable thermal-hygrometric profiles across the test volume. The chamber utilizes dual-stage refrigeration (cascade system) with R23/R404A refrigerants—selected for low global warming potential (GWP) and regulatory compliance through 2030 per U.S. EPA SNAP program guidelines. Its forced-air circulation system features multi-blade centrifugal fans and optimized airflow ducting (top-out/bottom-in configuration), ensuring uniform temperature and humidity distribution within ±2 °C and ±2% RH across the defined working space, validated per ISO 16750-4 Annex A and GB/T 10586 methodology (measurement at 1/10 distance from chamber walls).

Key Features

• Stainless steel construction: Interior chamber fabricated from polished SUS304 stainless steel; exterior housing available in brushed SUS304 or rust-protected cold-rolled steel.
• Cascade refrigeration system: Equipped with either fully hermetic Tecumseh (France) or semi-hermetic Bitzer (Germany) compressors, enabling reliable operation down to –70 °C.
• Intelligent PID control: TEMI880 touchscreen controller with dual-language interface (English/Chinese), 0.1 °C / 0.1% RH resolution, and programmable logic for up to 120 user-defined test profiles (999 segments per program).
• Comprehensive safety architecture: Integrated protections include over-temperature/under-temperature cutoff, high-pressure and low-pressure alarms, phase failure detection, dry-run prevention for humidifier, water level monitoring, and automatic power disconnection upon fault detection.
• Network-ready operation: RS-232 serial interface standard; optional LAN connectivity enables remote program upload/download, real-time data logging, machine status monitoring, and scheduled power cycling via PC-based software.

Sample Compatibility & Compliance

The AP-HX-80C accommodates electronic components, PCB assemblies, automotive ECUs, polymer materials, medical device housings, and consumer electronics under controlled thermal-hygrometric loads. Its internal dimensions (40 × 50 × 40 cm) support standard sample racks (2-tier included), a 100 mm observation window, and a 50 mm cable port for external sensor integration. All operational parameters comply with GLP-aligned documentation requirements: controller logs timestamped temperature/humidity values with audit trail capability, supporting traceability for ISO/IEC 17025-accredited laboratories. Regulatory alignment includes GB/T 2423.1 (cold), GB/T 2423.2 (dry heat), GB/T 2423.3 (constant damp heat), GB/T 2423.4 (cyclic damp heat), and MIL-STD-810G Method 507.5 (temperature-humidity-vibration combined testing).

Software & Data Management

The TEMI880 controller supports local data storage (SD card slot optional) and provides CSV export of time-stamped measurement records. When connected via RS-232 or Ethernet, third-party SCADA or LIMS platforms can ingest live process variables using Modbus RTU or ASCII protocol. The system maintains full calibration history and event logs—including alarm triggers, setpoint changes, and manual overrides—with tamper-resistant timestamps. For regulated environments, optional firmware upgrades enable 21 CFR Part 11-compliant electronic signatures, role-based access control, and secure audit trail archiving—meeting FDA, EU Annex 11, and ISO 13485 requirements for medical device validation.

Applications

This chamber serves critical functions across multiple stages of the product lifecycle: accelerated aging of conformal coatings and encapsulants; thermal cycling validation of solder joints per IPC-J-STD-020; preconditioning of lithium-ion battery modules prior to safety testing; verification of seal integrity in IP67-rated enclosures; qualification of optical sensors under condensing humidity; and environmental stress screening (ESS) of avionics subassemblies per DO-160 Section 4. It is routinely deployed in QC labs of Tier-1 automotive suppliers, contract manufacturers serving IoT hardware clients, and R&D centers validating next-generation wearables and edge AI devices.

FAQ

What temperature and humidity ranges does the AP-HX-80C support?

Standard operating range is –70 °C to +150 °C and 20–98% RH. Custom configurations are available for extended low-temperature performance (–80 °C) or ultra-low humidity (<10% RH) upon request.

Is the chamber compliant with international environmental testing standards?

Yes—it meets GB/T 10586 (wet heat), GB/T 10592 (temperature cycling), IEC 60068-2-1/2/14/30, MIL-STD-810G Method 502.5/507.5, and GJB 150.9 for military-grade environmental simulation.

Can test data be exported for regulatory submission?

All recorded data is exportable as timestamped CSV files. With optional Part 11 firmware, the system supports electronic signatures, audit trails, and user permission levels required for FDA/EU MDR submissions.

What maintenance is required to ensure long-term calibration stability?

Annual verification using NIST-traceable temperature/humidity probes is recommended. Compressor oil analysis and refrigerant leak checks should be performed every 24 months in continuous-use environments.

Does Apkji provide installation and commissioning support outside China?

Yes—on-site IQ/OQ documentation, field calibration, and operator training are available globally through authorized service partners, with technical documentation supplied in English.
