Overview
The Jinhuhu JH-2026 Series High-Low Temperature Environmental Test Chamber is an engineered solution for accelerated reliability validation under controlled thermal stress conditions. Designed in accordance with the fundamental principles of convective heat transfer and closed-loop PID-controlled thermoregulation, this chamber enables precise simulation of extreme ambient temperature profiles—ranging from −70 °C to +150 °C—to assess material integrity, component functionality, and system-level performance across thermal cycling, storage, and operational life-test protocols. Its dual-stage compressor refrigeration architecture ensures stable low-temperature hold capability without cryogenic consumables, while the insulated stainless-steel inner chamber and multi-point air distribution system minimize thermal gradients and support reproducible test outcomes. The JH-2026 series is widely deployed in R&D laboratories, QC/QA departments, and third-party certification bodies for compliance testing against ISO 16750-4 (road vehicles), IEC 60068-2-1/2 (cold/heat tests), GB/T 2423.1–2 (Chinese national standards), and UN ECE R100 (electric vehicle battery thermal safety).
Key Features
- Temperature control stability: ±0.5 °C fluctuation (1σ, over 30 min at steady state), validated per IEC 60068-3-5 Annex A
- Uniform thermal field: ≤2.0 °C spatial deviation across working volume (measured at 9-point grid per ISO 16750-4)
- Explosion-proof configuration available: Meets IEC 60079-0 general requirements and GB 3836.1–2021 for Group II hazardous locations
- Modular structural design: Inner chamber fabricated from SUS304 stainless steel; double-wall vacuum-insulated construction with polyurethane foam (≥120 mm thickness)
- Dual-stage refrigeration system: Uses environmentally compliant R404A/R23 cascade cycle for reliable sub-zero operation down to −70 °C
- Programmable controller: 10.4″ TFT touchscreen interface supporting up to 99 segments, 999 cycles, and ramp-soak-hold profiles with real-time deviation logging
- Safety redundancy: Triple-layer protection including independent over-temperature cutoff (mechanical backup), phase failure detection, compressor high-pressure shutdown, and door interlock circuit
Sample Compatibility & Compliance
The JH-2026 accommodates a broad spectrum of physical specimens—from compact PCB assemblies and lithium-ion pouch cells to automotive ECUs and aerospace avionics enclosures—within its customizable interior dimensions. Standard configurations support samples up to 500 mm × 500 mm × 500 mm; non-standard builds are engineered to customer-specified footprint, mass loading, and thermal inertia constraints. All units undergo factory calibration traceable to NIM (National Institute of Metrology, China) and include as-delivered verification reports per ISO/IEC 17025 requirements. The system complies with GLP-aligned data integrity practices: audit trails record operator ID, parameter changes, alarm events, and calibration history. Optional FDA 21 CFR Part 11 compliance packages include electronic signatures, role-based access control, and encrypted database archiving.
Software & Data Management
Jinhuhu’s proprietary TestLink™ software (v4.2+) provides local and remote monitoring via Ethernet or RS485. It supports real-time graphing of up to 16 channels (chamber setpoint, chamber actual, sensor A–D, compressor status, etc.), automated report generation in PDF/CSV/XLSX formats, and seamless integration with LIMS platforms through OPC UA or Modbus TCP. Raw time-series data is timestamped with millisecond resolution and stored on-board SSD (128 GB standard) with automatic rollover. For regulated environments, optional 21 CFR Part 11 modules enforce user authentication, electronic signature workflows, and immutable audit logs—fully compatible with GMP and ISO 13485 quality management systems.

FAQ
What is the typical lead time for custom-configured JH-2026 chambers?
Standard models ship within 15–20 working days after order confirmation. Non-standard dimensions, explosion-proof variants, or integrated humidity control extend lead time to 6–10 weeks depending on component availability and validation scope.
Does the JH-2026 support remote diagnostics and predictive maintenance?
Yes. With optional IoT gateway add-on, the chamber streams operational telemetry (compressor current, condenser temp, refrigerant pressure) to Jinhuhu’s cloud platform. Anomaly detection algorithms flag early-stage degradation patterns (e.g., declining COP, rising superheat), enabling proactive service dispatch.
Can the chamber be integrated into existing MES or SCADA infrastructure?
Native Modbus TCP and OPC UA servers are embedded. Custom API wrappers (RESTful JSON) are available upon request for ERP/MES synchronization—including batch ID binding, test schedule ingestion, and pass/fail status push notifications.
Is third-party calibration certification included with delivery?
All units ship with a factory calibration certificate (NIM-traceable) covering temperature uniformity, fluctuation, and deviation at three setpoints (−40 °C, 25 °C, +85 °C). ISO/IEC 17025-accredited external calibration is available as a billable service.
How does Jinhuhu ensure long-term parts availability and firmware support?
Jinhuhu maintains ≥10-year component obsolescence buffers for all critical subsystems (controllers, compressors, sensors). Firmware updates are released biannually and supported for minimum 12 years post-product discontinuation—documented in the company’s Product Lifecycle Policy (PLP-2023 Rev.2).
