LabCompanion UP-225U Temperature and Humidity Controlled Environmental Test Chamber

Overview

The LabCompanion UP-225U is a precision-engineered temperature and humidity controlled environmental test chamber designed for rigorous reliability validation of electronic components, optoelectronic devices, PCB assemblies, lithium-ion batteries, and advanced materials under dynamically programmed climatic stress conditions. Based on the principle of forced convection air circulation combined with dual independent control loops—PID-regulated heating/cooling and vapor-pressure-based humidification/dehumidification—the UP-225U delivers high reproducibility in both steady-state and transient thermal-hygrometric profiles. Its architecture supports full-spectrum environmental simulation from deep-cold (−60 °C) to high-temperature bake (+150 °C), coupled with precise humidity modulation between 20% and 98% RH—extendable to ≤5% RH via optional desiccant-assisted dehumidification. The chamber’s structural integrity is reinforced by SUS304 stainless steel interior walls, high-density rigid polyurethane insulation (glass wool variant at >150 °C operation), and a corrosion-resistant brushed stainless steel exterior.

Key Features

• Japanese ETAC820 programmable touchscreen controller with multilingual UI (English, Chinese, Japanese), supporting up to 1000 user-defined test steps across 10 customizable patterns
• Full-segment programmability: individual step duration (0–999 h 59 min), loop count (1–999 cycles per segment or global), cross-segment branching, and real-time remaining time display
• Intelligent power-loss recovery: automatic resumption of interrupted test sequences without data loss or manual reconfiguration
• BTHC (Balanced Temperature & Humidity Control) algorithm enabling simultaneous, decoupled regulation of temperature and humidity—minimizing overshoot and improving stability during ramp transitions
• Horizontal laminar airflow system with adjustable internal baffles ensures ±0.5 °C temperature uniformity and ≤±2.5% RH spatial consistency across the entire 225 L working volume
• Modular refrigeration architecture: hermetically sealed compressors, environmentally compliant R404A/R23 cascade circuits (for −60 °C capability), and redundant safety interlocks including high-temp cutoff, over-humidity shutoff, and compressor discharge protection
• Standard interface suite: USB port for parameter backup/export, RS-232/485 for SCADA integration, analog voltage outputs (0–10 V) for external logging, and Ethernet-ready firmware for remote monitoring via secure HTTP/HTTPS

Sample Compatibility & Compliance

The UP-225U accommodates diverse sample geometries—including 19″ rack-mounted instrumentation, smartphone-sized PCBs, fiber optic splices, and cylindrical battery cells—via two adjustable stainless steel shelves and a Ø50 mm cable/port access port. Its internal lighting, observation window (tempered double-glazed), and ergonomic door design facilitate non-intrusive visual inspection during active testing. The chamber conforms to international environmental test standards required for product certification and quality assurance workflows, including IEC 60068-2-1 (cold), -2 (dry heat), -14 (change of temperature), -3 (damp heat, steady state), and -30 (damp heat, cyclic); MIL-STD-810D Method 502.2 (low temperature), 507.2 (humidity), and 509.4 (combined temperature/humidity cycling); as well as Chinese national standards GB/T 2423.1, 2423.3, 2423.4, and 2423.34. It supports GLP-compliant audit trails when integrated with validated data acquisition systems meeting FDA 21 CFR Part 11 requirements.

Software & Data Management

The ETAC820 controller embeds an onboard 16 MB flash memory for persistent storage of up to 100 complete test logs (timestamped temperature/humidity setpoints, actual readings, alarm events, and system status). Data export is supported via USB mass storage mode in CSV format, compatible with MATLAB, Python pandas, and industry-standard SPC software. Optional LabCompanion CloudLink™ firmware enables encrypted TLS 1.2 communication for remote parameter adjustment, live dashboard viewing, and push notifications upon alarm activation—all accessible through role-based web interfaces. For regulated environments, optional 21 CFR Part 11 add-on modules provide electronic signatures, audit trail logging, and user permission hierarchies aligned with ISO/IEC 17025 and GMP Annex 11 expectations.

Applications

The UP-225U serves critical roles in accelerated life testing, qualification screening, and failure mode analysis across multiple sectors. In electronics manufacturing, it validates thermal cycling endurance of BGA solder joints and moisture sensitivity level (MSL) compliance per J-STD-020. For energy storage R&D, it simulates seasonal ambient exposure of LiCoO₂ and NMC pouch cells under variable humidity to assess electrolyte decomposition kinetics. In optical device development, it replicates tropical storage conditions for LCD modules and fiber Bragg grating sensors to quantify delamination risk and refractive index drift. Aerospace component suppliers use it for MIL-HDBK-344 compliance testing of avionics enclosures, while automotive Tier-1 suppliers deploy it for ISO 16750-4 environmental stress screening of ADAS ECUs. Its stable low-humidity capability also supports preconditioning of hygroscopic polymers prior to tensile or dielectric testing.

FAQ

What is the maximum allowable sample load volume inside the UP-225U chamber?
The recommended maximum sample volume is 1/3 of the internal chamber volume (i.e., ≤75 L) to preserve specified temperature/humidity uniformity and response time.
Can the UP-225U perform uninterrupted 1000-hour continuous tests?
Yes—its industrial-grade compressors, redundant condensate drainage, and self-diagnostic controller support unattended long-duration operation with scheduled maintenance intervals per OEM guidelines.
Is calibration documentation provided with shipment?
Each unit ships with a factory calibration certificate traceable to NIM (National Institute of Metrology, China), covering temperature (−60 °C to +150 °C) and humidity (20–98% RH) at three spatial points per ISO/IEC 17025.
Does the chamber support custom protocol scripting beyond ETAC820’s native pattern editor?
Via RS-485 Modbus RTU or optional Ethernet TCP/IP API, third-party test sequencers (e.g., NI TestStand, Keysight PathWave) can fully orchestrate chamber operations using open command sets.
How is condensation managed during rapid cooldown below dew point?
The system employs pre-cooled dry air purge and dynamic dew-point tracking algorithms to minimize condensate formation on samples and chamber surfaces—critical for moisture-sensitive semiconductor packaging.
