LabCompanion LP Series High-Temperature Aging & Environmental Test Chamber

Overview

The LabCompanion LP Series High-Temperature Aging & Environmental Test Chamber is an engineered environmental simulation system designed for rigorous reliability validation under controlled thermal and hygrothermal stress conditions. It operates on the principle of balanced temperature and humidity control (BTHC), integrating precise proportional-integral-derivative (PID) regulation with dual-channel PT100 platinum resistance sensors and dry-wet bulb humidity measurement. This architecture ensures stable, repeatable chamber performance across wide operational envelopes—from extreme low-temperature aging at −70°C to high-temperature endurance testing up to +150°C, combined with programmable humidity cycling from 20% to 98% RH. The chamber supports both steady-state and dynamic profile execution, enabling standardized environmental stress screening (ESS), accelerated life testing (ALT), and qualification per military, aerospace, automotive, and electronics industry requirements.

Key Features

• Modular capacity configuration: Seven standard internal volumes (80 L to 1000 L), each with fully documented internal/external dimensions and structural clearances for fixture integration.
• Multi-range temperature capability: Five configurable operating bands (H/R/L/U/S) accommodate diverse material and component testing needs—from consumer electronics qualification to high-reliability aerospace subsystem validation.
• BTHC (Balanced Temperature and Humidity Control) system: Achieves ±0.5°C temperature uniformity and ±1.0% RH stability via coordinated compressor modulation, electric heating, and shallow-tray steam humidification—minimizing thermal overshoot and condensation lag.
• Robust thermal management: Dual-stage hermetic refrigeration circuit using environmentally compliant refrigerants (R404A or R507 alternatives), paired with high-efficiency centrifugal air circulation and optimized polyurethane/glass wool composite insulation (≥120 mm effective thickness).
• Industrial-grade controller: Q8 touchscreen HMI with real-time graphing, multi-segment profile programming, alarm logging, and USB data export—designed for traceable operation in GLP/GMP-aligned laboratories.
• Comprehensive safety architecture: Integrated protection against compressor overheat/overcurrent, refrigerant high-pressure fault, heater dry-run, chamber overtemperature, and reservoir low-water conditions—with visual and relay-based fail-safe outputs.

Sample Compatibility & Compliance

The LP Series accommodates a broad spectrum of physical specimens—including PCB assemblies, lithium-ion battery modules, optical components (LCDs, fiber optic connectors), polymer housings, and sensor subassemblies—without requiring custom mounting interfaces. Standard features include dual adjustable sample racks, 50 mm cable port (left-side), interior LED lighting, and observation window with double-layer low-emissivity glass. All models comply with national and international environmental test standards, including GB/T 10586–1989 (wet heat), GB/T 10592–1989 (temperature cycling), GB/T 2423.4–1993 (damp heat cyclic), IEC 60068-2-14 (change of temperature), MIL-STD-810D Method 502.2 (low temperature) and 507.2 (humidity), and GJB 150.9–1986 (military wet heat). Full compliance documentation—including calibration certificates traceable to CNAS-accredited labs—is provided upon request.

Software & Data Management

The Q8 controller firmware supports audit-ready data integrity per FDA 21 CFR Part 11 requirements when configured with optional password-protected user roles, electronic signature capture, and immutable event logs. Real-time monitoring includes temperature/humidity trend graphs, deviation alerts, and cycle completion notifications. Raw data exports in CSV format are compatible with statistical process control (SPC) platforms such as Minitab and JMP. Optional RS485/RS232 communication enables integration into centralized lab information management systems (LIMS) or SCADA networks. No proprietary software installation is required—data acquisition and reporting remain native to the embedded controller interface.

Applications

This chamber serves critical functions across product development and quality assurance workflows: thermal aging of dielectric materials per ASTM D3045; humidity-induced corrosion testing of printed circuit boards (IPC-TM-650 2.6.16); preconditioning of automotive ECUs prior to EMC evaluation; shelf-life modeling of medical device packaging under ISO 11607; and qualification of photovoltaic module encapsulants per IEC 61215 thermal cycling protocols. Its extended low-temperature capability (−70°C) also supports cryogenic storage validation for biopharmaceutical transport containers and cold-chain logistics verification.

FAQ

What is the maximum allowable ambient temperature for continuous operation?
The chamber requires an ambient environment between +5°C and +30°C with adequate ventilation and no direct solar exposure.
Can the LP Series perform uninterrupted 1000-hour high-temperature aging tests?
Yes—its redundant safety systems, compressor thermal management, and sealed refrigerant circuit support unattended long-duration runs, provided routine maintenance intervals (per manual Section 6.2) are observed.
Is third-party calibration certification available?
Certified calibration reports traceable to NIM (National Institute of Metrology, China) or CNAS-accredited providers can be arranged pre-shipment or on-site.
Does the controller support custom test profiles with ramp/soak/humidity modulation?
Yes—the Q8 interface allows up to 99 segments per program, with independent setpoint scheduling for temperature and humidity, including rate-limited transitions and conditional branching logic.
Are replacement parts and technical support accessible outside China?
LabCompanion maintains regional service partners in North America, EU, and Southeast Asia; spare parts inventory and firmware updates are distributed through authorized distributors under warranty terms.
