LabCompanion HH-72 High Temperature Aging Test Chamber

Overview

The LabCompanion HH-72 is a precision-engineered forced-convection high-temperature aging test chamber designed for controlled thermal exposure of non-flammable and non-explosive materials under laboratory and production-line conditions. It operates on the principle of uniform convective heat transfer, utilizing a horizontally mounted fan to circulate heated air across calibrated internal surfaces—ensuring reproducible thermal profiles critical for reliability testing, accelerated aging, and process validation. Engineered for long-term stability at elevated temperatures up to 300°C, the HH-72 meets the stringent thermal consistency requirements of electronics manufacturing, semiconductor packaging, passive component qualification (e.g., capacitors, resistors, quartz crystals), and optoelectronic device processing (LED/LCD modules). Its microprocessor-based PID temperature controller—paired with a Class A PT100 sensor—enables stable setpoint maintenance with minimal overshoot and drift, supporting compliance with ISO 17025 calibration traceability frameworks when integrated into accredited laboratory quality systems.

Key Features

• Forced convection airflow architecture optimized for thermal uniformity (±2.5°C across 72 L working volume) and rapid thermal response (RT to 100°C in ≤15 minutes)
• SUS430 stainless steel interior (≥1.2 mm thickness) resistant to oxidation and thermal fatigue at sustained temperatures up to 300°C
• Dual-layer insulation system comprising superfine glass wool and rock wool, minimizing external surface temperature rise and energy consumption
• Adjustable inlet/exhaust ventilation ports enabling controlled ambient exchange—critical for moisture-sensitive or outgassing-prone samples
• Microprocessor PID controller with dual LED display showing both setpoint and real-time chamber temperature, adjustable via intuitive Δ/▽ keys
• Programmable timer (0–999 minutes) with auto-shutdown function, supporting unattended batch processing in QC and R&D environments
• Integrated safety architecture including over-temperature cut-off (dual-stage), ground-fault protection, and thermal fuse redundancy

Sample Compatibility & Compliance

The HH-72 accommodates standard industry sample configurations—including PCB assemblies, wafer trays, ceramic substrates, polymer films, and pharmaceutical excipient batches—within its 450 × 400 × 400 mm usable workspace. Its non-corrosive SUS430 chamber and inert heating elements ensure compatibility with halogen-free solder pastes, conformal coatings, and low-outgassing encapsulants. The unit complies with IEC 60068-2-2 (Environmental Testing – Part 2-2: Tests – Test B: Dry Heat) and supports adherence to ASTM D3418 (Transition Temperatures of Plastics by DSC), IPC-9701 (Performance Requirements for Solder Interconnections), and JEDEC JESD22-A108 (Temperature Cycling). While not intrinsically rated for hazardous locations, it satisfies UL 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) when installed per manufacturer-specified clearances and grounding protocols.

Software & Data Management

The HH-72 operates as a standalone instrument with no embedded data logging or remote interface capability. However, its analog voltage output (0–5 V or 4–20 mA, configurable per OEM specification) enables integration with third-party SCADA systems, PLCs, or validated data acquisition platforms compliant with FDA 21 CFR Part 11. When deployed within GLP/GMP-regulated facilities, users may implement external chart recorders or time-stamped digital loggers meeting ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Calibration intervals should follow ISO/IEC 17025 guidelines, with annual verification against NIST-traceable reference thermometers at three spatial points (center, top corner, bottom corner) per IEC 60068-3-5.

Applications

• Accelerated life testing of electronic components under thermal stress (e.g., MIL-STD-217, Telcordia SR-332)
• Bake-out cycles for moisture removal prior to hermetic sealing or wire bonding
• Pre-conditioning of polymeric insulators, adhesives, and potting compounds prior to electrical testing
• Thermal stabilization of optical filters, laser diodes, and MEMS devices during final assembly
• Residual solvent evaporation in coated medical device substrates per ISO 10993-12
• Stability assessment of active pharmaceutical ingredients (APIs) and excipients under ICH Q1A(R2) long-term and accelerated storage conditions

FAQ

What is the maximum continuous operating temperature of the HH-72?
The chamber is rated for continuous operation up to 300°C, with thermal stability maintained per specified fluctuation limits.
Does the HH-72 support ramp-and-soak temperature profiling?
No—it operates exclusively in constant-temperature (setpoint hold) mode; programmable ramping requires external controller integration.
Can the HH-72 be used for sterilization or microbial decontamination?
No—this unit lacks validated biological lethality performance and does not meet ISO 17665 or EN 554 requirements for steam or dry-heat sterilization.
Is the internal volume fully accessible for large fixtures or jigs?
Yes—the 450 × 400 × 400 mm cavity allows installation of custom sample racks, thermocouple trees, or multi-tier carriers without obstruction from internal fans or heaters.
What maintenance is required to sustain temperature accuracy over time?
Annual verification of PT100 sensor calibration and fan motor performance is recommended; periodic inspection of door gasket compression and insulation integrity ensures long-term uniformity retention.
