LabCompanion RZ-80 Benchtop Programmable Temperature and Humidity Chamber

Overview

The LabCompanion RZ-80 is a compact, benchtop programmable temperature and humidity chamber engineered for precision environmental simulation in quality control laboratories, R&D facilities, and electronics reliability testing environments. It operates on the principle of Balanced Temperature and Humidity Control (BTHC), where proportional-integral-derivative (PID) algorithms dynamically regulate heating, cooling, and humidification outputs to match real-time thermal and moisture load losses—enabling stable, repeatable conditioning over extended test durations. Unlike basic static chambers, the RZ-80 supports both steady-state (constant) and dynamic (cyclic) profiles, making it suitable for accelerated stress testing per IEC 60068-2-1, IEC 60068-2-2, and IEC 60068-2-78 standards. Its -20°C to +150°C temperature range and 30–95% RH capability cover common requirements for component burn-in, material aging, pharmaceutical stability studies (ICH Q1A), and packaging validation.

Key Features

• Compact footprint (94 × 86 × 83 cm external) optimized for limited lab space without compromising internal volume (40 × 50 × 40 cm)
• BTHC system with dual-loop PID control ensures minimal thermal overshoot and humidity hysteresis during ramp-and-soak cycles
• Hermetically sealed, imported compressor with eco-friendly refrigerant (non-CFC/HFC blend compliant with EU F-Gas Regulation)
• SUS#304 stainless steel interior and exterior construction for corrosion resistance and cleanroom-compatible maintenance
• High-efficiency polyurethane insulation (≥80 mm thickness) minimizes energy consumption while maintaining uniformity
• U-shaped immersion heater and finned-tube humidifier enable rapid, condensation-free RH response
• Double-glazed, vacuum-insulated observation window (210 × 270 mm) with integrated 13 W viewing lamp for non-intrusive sample monitoring
• Programmable controller with full English LCD interface, supporting up to 120 segments, 99 cycles, and user-defined alarm thresholds

Sample Compatibility & Compliance

The RZ-80 accommodates standard test specimens including PCB assemblies, polymer films, battery cells, medical device packaging, and small-scale pharmaceutical dosage forms. Its internal geometry allows unobstructed airflow via a rear-mounted 90 W stainless steel axial fan and multi-blade impeller—ensuring <±2°C spatial uniformity (per ASTM E744-22 measurement protocol at 1/10 wall distance). The chamber meets structural and operational prerequisites for ISO 17025-accredited labs: traceable PT100 sensors (calibration certificate optional), hardware-based safety interlocks (high-temp cutoff, compressor high-pressure switch), and mechanical redundancy in refrigerant flow control. While not pre-certified to UL or CE as a standalone unit, its subsystems—including electrical insulation, grounding continuity, and refrigerant containment—conform to IEC 61000-6-3 (EMC) and IEC 61000-6-4 design guidelines.

Software & Data Management

The embedded Korean-made controller provides local data logging (up to 30 days at 1-minute intervals) with timestamped temperature/humidity curves viewable directly on the LCD. Optional LAN interface enables integration into centralized lab management systems via Modbus TCP or custom HTTP API endpoints. Raw CSV export supports post-processing in MATLAB, Python (pandas), or LIMS platforms. Audit trail functionality—including operator ID tagging, parameter change logs, and alarm event timestamps—facilitates compliance with FDA 21 CFR Part 11 when paired with validated third-party software. All firmware updates are delivered via secure USB dongle; no cloud dependency or remote vendor access is required.

Applications

• Electronics: Thermal cycling of semiconductors per JESD22-A104, solder joint reliability assessment
• Automotive: Climate endurance testing of interior trim materials under DIN 75200 conditions
• Pharmaceuticals: ICH Q5C stability protocols for lyophilized proteins and blister-packaged tablets
• Polymers: Hygrothermal aging of ABS, PC, and PEEK components per ISO 11359-2
• Quality Assurance: Incoming inspection of hygroscopic raw materials (e.g., lithium-ion cathode powders)
• Academic Research: Controlled microenvironment studies for biomaterial degradation kinetics

FAQ

What is the typical calibration interval for the RZ-80’s PT100 sensors?
We recommend annual calibration against NIST-traceable references; internal verification routines allow daily zero-point checks using built-in self-diagnostics.
Can the RZ-80 perform rapid temperature transitions below 0°C while maintaining humidity?
Yes—its multi-stage evaporator and variable refrigerant flow control permit simultaneous sub-zero cooling and controlled dehumidification down to 30% RH, though dwell time below freezing with active humidification is limited by condensation risk.
Is the controller compatible with LabVIEW or Python-based automation frameworks?
Via optional LAN module: native Modbus TCP support enables direct SCPI-style command integration; Python libraries (e.g., pymodbus) are routinely used for script-driven profile sequencing.
Does the chamber include validation documentation (IQ/OQ/PQ templates)?
Standard delivery includes factory performance test reports (FAT); IQ/OQ templates aligned with ISO/IEC 17025 Annex A.3 are available upon request for GxP-regulated users.
What maintenance is required for long-term reliability?
Quarterly inspection of condensate drain lines, biannual cleaning of evaporator fins and humidifier tank, and annual refrigerant pressure verification—no consumables beyond distilled water for humidification.
