Overview
The LabCompanion RZ-80 is a precision-engineered programmable temperature and humidity environmental test chamber designed for rigorous reliability validation under controlled climatic conditions. It operates on the principle of forced-air convection with dual independent control loops—one for temperature (via PID-regulated electric heating and refrigeration circuits) and one for relative humidity (via surface-evaporation stainless steel humidifier and refrigerated dehumidification). The chamber delivers stable, repeatable exposure profiles across a wide operational envelope: −20 °C to +150 °C and 20–98 %RH—enabling simulation of real-world storage, transport, and operational environments encountered by electronic components, aerospace hardware, automotive modules, and medical devices. Its architecture conforms to the physical and metrological requirements of international environmental testing standards, serving as a core platform for accelerated life testing, qualification screening, and design verification in ISO/IEC 17025-accredited laboratories.
Key Features
- Q8-901 bilingual (English/Chinese) color touchscreen controller with intuitive graphical interface, supporting up to 120 programs, 1200 segments, and 999-cycle looping—each segment configurable with duration up to 99 hours 59 minutes.
- Advanced 9-group PID parameter tuning for dynamic thermal and hygric compensation, ensuring minimal overshoot and high setpoint fidelity during ramp-and-soak profiles.
- Dual-loop independent control architecture with real-time feedback from calibrated PT100 sensors (standard) and optional high-accuracy capacitive RH transducers.
- Front-mounted automatic water feed system with level monitoring, eliminating manual refilling and reducing operator intervention.
- Vacuum double-glazed observation window with built-in anti-frost heater, enabling unobstructed visual inspection without condensation interference.
- Uniform airflow design featuring rear-wall-mounted centrifugal blower and optimized baffle configuration—validated to meet ±2 °C temperature and ±2 %RH (≥75 %RH) uniformity per GB 10586-89 and IEC 60068-3-5.
- Robust mechanical construction: cold-rolled steel exterior with electrostatic epoxy coating; SUS304 stainless steel interior; high-efficiency polyurethane insulation (≥100 mm thickness).
- Comprehensive safety suite including over-temperature, over-humidity, compressor high-pressure, and door-open alarms—with fault codes displayed directly on the controller screen.
Sample Compatibility & Compliance
The RZ-80 accommodates standard test specimens up to 500 mm (W) × 600 mm (H) × 500 mm (D), with optional 50 mm diameter cable/port access and two adjustable stainless steel shelves. Its performance meets or exceeds the technical criteria specified in GB 10586-89 (Humidity Test Chambers), GB 10592-89 (Temperature Test Chambers), and IEC 60068-2 series for environmental testing of electrotechnical products. It supports full compliance with MIL-STD-810F Method 507.4 (Humidity), 501.4 (High Temperature), 502.4 (Low Temperature), and 509.5 (Combined Temperature/Humidity Cycling), as well as JESD22-A101-B (Constant Temperature/Humidity), A103-C (High-Temp Storage), and A119 (Low-Temp Storage). All calibration and verification procedures align with ISO/IEC 17025 requirements, and data traceability supports GLP/GMP audit readiness when paired with optional USB logging or RS485-to-PC connectivity.
Software & Data Management
The embedded Q8-901 controller provides native data logging at user-defined intervals (1–600 seconds), storing up to 100,000 data points internally. Optional USB flash drive support enables export of time-stamped CSV files containing temperature, humidity, program status, and alarm history—fully compatible with Excel, MATLAB, and LIMS platforms. RS232 and RS485 interfaces allow integration into centralized lab management systems via Modbus RTU protocol. When configured with LabCompanion’s optional remote monitoring software (sold separately), users gain secure web-based access to live chamber status, historical trend charts, and automated email/SMS alerts upon deviation or alarm activation. All logged data includes immutable timestamps and operator ID fields—meeting FDA 21 CFR Part 11 requirements for electronic records and signatures when deployed with appropriate system validation documentation.
Applications
The RZ-80 is routinely deployed in QC/QA labs for accelerated stress testing of printed circuit boards (PCBs), connectors, sensors, and encapsulated semiconductor packages. It supports IPC-J-STD-020 moisture sensitivity level (MSL) preconditioning, JEDEC J-STD-002 solderability testing pre-bake cycles, and MIL-PRF-38534 device burn-in protocols. In materials science, it facilitates polymer aging studies per ASTM D3045 and ISO 4892-2, while in medical device development, it fulfills IEC 60601-1 environmental robustness requirements. Automotive Tier-1 suppliers use it for ISO 16750-4 (climate resistance) validation, and academic researchers apply it to corrosion acceleration tests on coated metals per ASTM B117 and ISO 9227. Its programmable flexibility also supports custom cycling profiles for battery thermal runaway propagation studies and photovoltaic module damp heat testing (IEC 61215).
FAQ
What is the maximum allowable load volume inside the RZ-80 chamber?
The internal working volume is 150 L (500×600×500 mm). For optimal thermal/hygrometric uniformity, loaded volume should not exceed 30 % of total internal volume—i.e., ≤45 L of solid test objects.
Does the RZ-80 support validation protocols such as IQ/OQ/PQ?
Yes. LabCompanion provides factory-issued calibration certificates traceable to NIM (China National Institute of Metrology), along with optional IQ/OQ documentation kits—including sensor placement diagrams, tolerance checklists, and protocol templates aligned with ISO/IEC 17025 and Annex 11.
Can the controller be upgraded to support Ethernet or Wi-Fi communication?
The base Q8-901 controller supports only RS232/RS485. Ethernet or Wi-Fi functionality requires external gateway hardware (e.g., Moxa EDS-205A) and is not natively integrated.
Is the refrigeration system serviceable in the field?
The unit uses either a hermetic Tecumseh (France) or semi-hermetic Copeland (Germany) compressor. Field service is supported via standardized service ports, and LabCompanion offers authorized technician training and spare parts logistics through its global distributor network.
How is humidity accuracy verified across the full 20–98 %RH range?
Humidity calibration is performed using NIST-traceable chilled-mirror hygrometers at three points: 35 %RH, 65 %RH, and 90 %RH—per IEC 60068-3-2—and documented in the出厂 calibration report shipped with each unit.
