High-Temperature Aging Test Chamber – OK-T Series (RT+10°C to 300°C, ±0.5°C Control Accuracy, Stainless Steel Interior)

Overview

The OK-T Series High-Temperature Aging Test Chamber is an engineered environmental test system designed for accelerated thermal aging, drying, baking, and sterilization of non-volatile, non-flammable materials in industrial, academic, and R&D laboratories. Based on forced-air convection principles, the chamber employs bottom-mounted dual independent nickel-chromium infrared heating elements coupled with a high-efficiency axial fan to ensure uniform air circulation through a dedicated duct system—air enters from the base, passes over heated surfaces, and exits via left-side vents to maintain consistent thermal distribution across the working volume. The unit operates within a calibrated temperature range from ambient +10°C up to 300°C (with optional configuration for 500°C), meeting the procedural requirements of GB/T 2423.2 and IEC 60068-2-2 for high-temperature environmental testing of electrical and electronic components. Its robust architecture supports long-duration stability tests under controlled thermal stress, enabling evaluation of material degradation, coating adhesion loss, seal integrity failure, and insulation performance decline over time.

Key Features

• Microprocessor-based digital touch controller with real-time temperature display, programmable timer (0–999 minutes), and auto-start/stop functionality
• Dual-zone independent heating control system ensures precise thermal management and energy efficiency
• SUS#304 stainless steel interior chamber resists oxidation and corrosion at elevated temperatures; exterior constructed from powder-coated cold-rolled steel for mechanical durability
• PT100 platinum resistance sensor provides high-stability temperature feedback with traceable calibration characteristics
• Forced-air convection design achieves ±1.5°C temperature uniformity across the full working volume per ISO 17025-aligned verification protocols
• Integrated safety protections include over-temperature alarm, thermal cut-off fuse, ground-fault circuit interruption (GFCI), and door-interlocked power cutoff
• Three adjustable stainless steel wire shelves included as standard; additional shelves and custom tray configurations available upon request

Sample Compatibility & Compliance

The OK-T chamber is intended for use with solid, non-volatile, non-explosive, and non-dripping samples—including printed circuit boards, polymer housings, ceramic substrates, metal fasteners, and pharmaceutical packaging materials. It is not suitable for flammable solvents, volatile organic compounds (VOCs), or moisture-laden specimens requiring humidity control. All units undergo factory calibration against NIST-traceable reference standards and conform to national and international regulatory frameworks including GB/T 2423.2 (equivalent to IEC 60068-2-2), and support GLP-compliant documentation when paired with external data loggers. Optional validation packages—including IQ/OQ documentation templates and temperature mapping reports—are available to meet FDA 21 CFR Part 11 and ISO/IEC 17025 audit requirements.

Software & Data Management

While the standard configuration features a standalone microcontroller interface, optional RS485 communication port enables integration with PC-based monitoring software (e.g., LabVIEW or custom SCADA systems) for remote parameter setting, real-time data logging, and alarm event history export. The controller stores up to 10 user-defined temperature profiles with ramp/soak sequences. Audit trail functionality—including operator ID entry, parameter change timestamps, and deviation alerts—is supported via external compliant software solutions aligned with 21 CFR Part 11 electronic record requirements. Data export formats include CSV and PDF for inclusion in test reports and quality management system (QMS) archives.

Applications

• Accelerated life testing of electronic assemblies per JEDEC JESD22-A108
• Thermal stability assessment of adhesives, encapsulants, and conformal coatings
• Pre-conditioning of sensors, batteries, and optoelectronic modules prior to functional testing
• Baking cycles for powder-coated metal parts and PCB solder mask curing verification
• Material qualification per automotive standards (e.g., AEC-Q200) and aerospace specifications (e.g., SAE AS4520)
• Research-scale thermal degradation kinetics studies in polymer science and materials engineering labs

FAQ

What is the maximum allowable operating temperature for the standard OK-T-72 model?

The standard configuration supports up to 300°C; extended-range models capable of 500°C operation are available with upgraded insulation and thermocouple wiring.

Can this chamber be used for humidity-controlled aging tests?

No—this is a dry-heat-only chamber. Humidity control requires a combined temperature/humidity test chamber (e.g., OK-TH series).

Is third-party calibration certification included with shipment?

A factory calibration report is provided; NIST-traceable calibration certificates issued by accredited laboratories are available as an add-on service.

What maintenance intervals are recommended for sustained accuracy?

Annual verification of temperature uniformity and controller accuracy is advised; heater element resistance checks and fan lubrication should be performed every 6 months in continuous-use environments.

Does the unit comply with CE or UL safety directives?

The chamber meets general safety requirements of IEC 61010-1; CE marking is available upon request with additional EMC and LVD testing. UL listing requires customization and separate certification process.
