JianHu JH-Series High-Temperature Aging Test Chamber

Overview

The JianHu JH-Series High-Temperature Aging Test Chamber is an industrial-grade environmental test system engineered for accelerated thermal aging evaluation of materials and components under controlled elevated temperature conditions. Based on the fundamental principle of Arrhenius reaction kinetics, this chamber accelerates degradation mechanisms—such as oxidation, polymer chain scission, interfacial delamination, and solder joint fatigue—by subjecting samples to sustained elevated temperatures within a thermally stable enclosure. Designed for reliability engineering laboratories, quality assurance departments, and R&D centers in electronics, automotive, aerospace, and polymer industries, the JH-Series provides a reproducible platform for predicting long-term service life, validating design margins, and verifying compliance with thermal endurance requirements defined in IEC 60068-2-2, MIL-STD-810H Method 501.5, and ASTM D3045.

Key Features

• Robust stainless-steel inner chamber construction with high-density mineral wool insulation and double-layer tempered glass viewing window for structural integrity and thermal retention
• PID-controlled electric heating system with redundant over-temperature protection (dual independent limit controllers per IEC 61000-6-2)
• Forced-air convection circulation via low-turbulence axial fans to ensure uniform thermal distribution across the working volume
• Compliance-ready architecture supporting traceable calibration protocols aligned with ISO/IEC 17025 requirements
• Front-access door with magnetic seal and mechanical latch to maintain chamber integrity during extended dwell cycles
• Integrated real-time monitoring of chamber ambient conditions including internal air temperature, heater status, and fan operation

Sample Compatibility & Compliance

The JH-Series accommodates a broad range of sample geometries—including PCB assemblies, molded plastic housings, battery modules, wire harnesses, and elastomeric seals—within its standard working volume configurations (optional custom volumes available). All models are designed to meet electromagnetic compatibility (EMC) standards per EN 61326-1 and safety requirements per EN 61010-1. While not a humidity-controlled chamber, its dry-heat environment supports testing per IPC-J-STD-020 (moisture sensitivity level preconditioning), JEDEC JESD22-A108 (temperature cycling without humidity), and UL 746B (polymeric material thermal endurance classification). Calibration certificates traceable to NIM (National Institute of Metrology, China) or equivalent national metrology institutes are available upon request.

Software & Data Management

The chamber operates via a dedicated 7-inch TFT-LCD touchscreen controller with embedded firmware supporting multi-step programmable profiles, real-time trend logging, and alarm event history. Data export is enabled via USB 2.0 interface in CSV format for integration into enterprise LIMS or QMS platforms. Optional RS485 Modbus RTU communication allows remote supervision through SCADA systems. Audit trail functionality—including operator ID, parameter changes, start/stop timestamps, and deviation alerts—meets baseline documentation requirements for GLP and internal QA procedures. Full validation documentation (IQ/OQ templates) and 21 CFR Part 11–compliant software packages are available as add-on services.
