LabCompanion RP-80U Temperature and Humidity Controlled Environmental Test Chamber

Overview

The LabCompanion RP-80U is a precision-engineered temperature and humidity controlled environmental test chamber designed for rigorous physical property evaluation under reproducible climatic conditions. It operates on the Balanced Temperature and Humidity Control (BTHC) principle—dynamically coordinating refrigeration, heating, steam humidification, and optional desiccant-based dehumidification to maintain stable setpoints across wide operational ranges. Engineered for laboratory-grade reliability and long-term stability, the RP-80U supports accelerated aging, material compatibility testing, electronics validation, packaging integrity assessment, and regulatory-compliant environmental stress screening in accordance with ISO 16750-4, IEC 60068-2-1, IEC 60068-2-2, and MIL-STD-810H methodologies. Its –60°C to +150°C temperature range and 10–98% RH (extendable to ≤5% RH with optional chemical desiccant module) capability make it suitable for both low-temperature storage simulation and high-humidity corrosion studies.

Key Features

• Energy-efficient architecture delivering up to 30% power reduction and 20% water savings versus conventional chambers, achieved via optimized heat exchanger design and intelligent compressor staging.
• Hermetically sealed French Tecumseh refrigeration unit—certified for continuous operation, low vibration, and extended service life (>25,000 hours MTBF).
• SUS304 stainless steel construction (interior and exterior), including seamless arc-welded corners and matte-finish surface treatment, ensuring corrosion resistance and cleanroom-compatible durability.
• Heated embedded observation window with integrated anti-fogging film eliminates condensation without mechanical wipers—enabling uninterrupted visual monitoring under all operating conditions.
• Dual-isolation humidification system: UL-shaped stainless steel steam generator physically separated from control boards and power circuits to prevent moisture ingress and electrical fault propagation.
• Intelligent air distribution: Centrifugal blower-driven forced convection with multi-directional adjustable vanes ensures ≤±2.0°C temperature uniformity and ±2.5% RH consistency across the 400×500×400 mm working volume.
• Real-time safety monitoring via redundant thermal fuses, high-pressure cut-offs, phase-loss protection, and door-open interlock—all triggering immediate shutdown and audible/visual alarm notification.
• USB-based data logging (up to 32 GB) with timestamped CSV export; compatible with Windows-based analysis tools and LIMS integration via optional RS-232/RS-485 SCADA interface.

Sample Compatibility & Compliance

The RP-80U accommodates diverse sample geometries—including PCB assemblies, polymer films, pharmaceutical blister packs, automotive sensors, and composite laminates—within its accessible internal chamber. Removable shelves and standardized 50 mm diameter cable ports (Φ50 mm) support instrumentation wiring for in-situ parameter acquisition. The chamber meets structural and performance requirements aligned with GLP (Good Laboratory Practice) documentation standards and supports audit-ready operation when paired with optional temperature/humidity auto-recorders compliant with FDA 21 CFR Part 11 electronic record provisions. Optional accessories—including pure water purification modules, CF card data readers, and double-glass viewing doors with glove ports—enable customization for ISO Class 5 cleanroom or GMP-aligned environments.

Software & Data Management

While the RP-80U operates via an embedded industrial-grade touchscreen controller with intuitive menu navigation, its communication architecture enables seamless integration into centralized lab management systems. The RS-232/RS-485 interface supports Modbus RTU protocol, allowing up to 200 units to be daisy-chained in distributed test facilities. All logged data—including chamber setpoints, actual readings, alarm events, and runtime diagnostics—are time-stamped and stored locally on removable USB media. Exported files conform to ASTM E2911-22 recommended formats for environmental test data archiving, facilitating traceability during regulatory submissions or internal quality audits.

Applications

• Accelerated shelf-life testing of medical devices per ISO 11607-1
• Thermal cycling validation of aerospace-grade adhesives and sealants
• Humidity-induced failure analysis of MEMS sensors and optoelectronic packages
• Plasticizer migration studies in PVC-based tubing under elevated RH
• Corrosion resistance evaluation of coated metallic substrates (ASTM B117, ISO 9227)
• Stability testing of lyophilized biologics per ICH Q5C guidelines
• Pre-conditioning of lithium-ion battery cells prior to electrochemical characterization

FAQ

What is the standard warranty coverage for the RP-80U?
LabCompanion provides a 24-month limited warranty covering parts and labor for defects in materials and workmanship under normal laboratory use.
Can the RP-80U operate continuously at –60°C and 10% RH simultaneously?
Yes—the chamber’s dual-stage refrigeration system and optional chemical desiccant module enable concurrent ultra-low temperature and low-humidity operation without performance degradation.
Is calibration certification included with shipment?
A factory-issued as-found/as-left calibration report (traceable to NIST standards) is provided; UKAS or ISO/IEC 17025-accredited third-party calibration is available upon request.
How is humidity controlled below 20% RH?
Standard operation uses steam generation; for sub-20% RH, the optional honeycomb-type chemical dehumidification system actively adsorbs moisture using regenerable silica gel media.
Does the RP-80U support remote monitoring via Ethernet or Wi-Fi?
The base model includes RS-232/RS-485 only; Ethernet/Wi-Fi connectivity requires the optional IPC gateway module, enabling web-based supervision through standard browsers.
