Overview
The OK-T-72 and OK-T-150 High-Temperature Aging Test Chambers are precision-engineered environmental test systems designed for accelerated thermal aging, stability testing, and reliability evaluation of electronic components, polymers, adhesives, coatings, and passive materials under controlled elevated temperatures. Operating on the principle of forced-air convection heating, these chambers utilize dual independent far-infrared Ni-Cr alloy heating elements combined with a microprocessor-regulated airflow system to achieve rapid thermal response, high spatial uniformity, and long-term temperature stability. The chambers comply with the procedural and performance requirements of GB/T 2423.2 (identical to IEC 60068-2-2, Test Bb: Dry Heat), making them suitable for qualification testing in R&D labs, QC departments, and third-party calibration facilities operating under ISO/IEC 17025 quality management frameworks.
Key Features
- Microprocessor-based digital touch controller with real-time temperature display, programmable timer (0–999 minutes), and intuitive keypad interface for setpoint adjustment and parameter monitoring.
- Dual-zone independent heating architecture enables precise thermal gradient management and improved energy efficiency during partial-load operation.
- Forced convection system featuring a bottom-mounted centrifugal blower and optimized lateral air duct design ensures uniform temperature distribution (±1.5°C across working volume) and minimizes thermal stratification.
- High-reliability sensing: PT100 platinum resistance thermometers (Class A tolerance) mounted at multiple strategic locations provide redundant feedback for closed-loop control and traceable calibration.
- Robust chamber construction: Interior lined with SUS#304 stainless steel for corrosion resistance and ease of cleaning; exterior finished with electrostatic powder-coated carbon steel for mechanical durability and chemical resistance.
- Integrated safety architecture includes dual-stage overtemperature protection (electronic limit + mechanical thermal cutoff), ground-fault circuit interruption (GFCI), and automatic power shutdown upon sensor failure or door opening during operation.
Sample Compatibility & Compliance
These test chambers accommodate non-volatile, non-flammable solid and semi-solid specimens conforming to standard sample trays or custom fixtures. They are explicitly unsuitable for testing flammable solvents, volatile organic compounds (VOCs), pressurized containers, or materials emitting condensable vapors—consistent with IEC 60068-1 general safety provisions. The OK-T series supports test protocols aligned with GB/T 2423.2, IEC 60068-2-2, MIL-STD-810H Method 501.7, and ASTM D3045 (Standard Practice for Heat Aging of Plastics). When operated within defined validation parameters—including documented temperature mapping, sensor calibration records, and routine preventive maintenance—the units support GLP-compliant data generation and are compatible with FDA 21 CFR Part 11 audit-trail configurations when integrated with compliant external data acquisition software.
Software & Data Management
While the standard configuration features a stand-alone microcontroller interface, optional RS485/Modbus RTU communication ports enable integration with centralized laboratory information management systems (LIMS) or SCADA platforms. Users may log time-stamped temperature profiles, alarm events, and runtime diagnostics using third-party compliant software (e.g., LabVIEW, WinCC, or custom Python-based DAQ tools). All controllers store minimum/maximum temperature values and cumulative operational hours. For accredited laboratories, full traceability is supported through periodic calibration certificates (NIST-traceable PT100 verification), uncertainty budgets, and configurable audit logs—facilitating internal audits and external assessments under ISO/IEC 17025 Clause 6.4.10 (Equipment Records).
Applications
- Accelerated life testing of printed circuit boards (PCBs), solder joints, and encapsulated semiconductor devices per JEDEC JESD22-A108.
- Thermal degradation studies of elastomers, thermoplastics, and flame-retardant cable jackets per UL 1581 or IEC 60811-501.
- Stability assessment of pharmaceutical excipients and packaging materials under ICH Q1A(R2) long-term and accelerated storage conditions.
- Pre-conditioning of sensors, batteries, and optoelectronic modules prior to functional testing or environmental stress screening (ESS).
- Validation of curing kinetics for epoxy resins, powder coatings, and adhesive formulations in materials development labs.
FAQ
What is the maximum allowable operating temperature for the OK-T-150 model?
The standard configuration supports up to 300°C; custom variants with upgraded insulation, high-temp gaskets, and reinforced heating elements are available for continuous operation at 500°C upon engineering review.
Can this chamber be used for humidity-controlled aging tests?
No — the OK-T series is a dry-heat-only chamber. For combined temperature/humidity profiling, consider the OK-TH series (temperature-humidity test chambers) compliant with IEC 60068-2-30.
Is the temperature controller compliant with FDA 21 CFR Part 11 requirements?
The embedded controller does not natively support electronic signatures or audit trails. However, when paired with validated external data logging software and secure network architecture, full Part 11 compliance can be achieved per organizational SOPs.
What calibration documentation is provided with shipment?
Each unit ships with a factory calibration report referencing NIST-traceable PT100 verification at three points (100°C, 200°C, 300°C), including as-found/as-left data, measurement uncertainty, and technician certification.
Are spare parts and service support available outside China?
Yes — authorized service partners operate in North America, EU, and APAC regions. Critical spares (heaters, controllers, PT100 sensors) are stocked globally with typical lead times under 10 business days.
