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 testing, material stability assessment, and accelerated aging studies in R&D, quality control, and regulatory compliance laboratories. It operates on the Balanced Temperature and Humidity Control (BTHC) principle—dynamically coordinating independent heating, cooling, humidification, and dehumidification subsystems to maintain highly stable and reproducible climatic conditions within the test volume. The chamber’s core architecture integrates a high-efficiency hermetic refrigeration circuit using environmentally compliant HFC refrigerant, stainless-steel internal construction (SUS304), and a multi-point air circulation system optimized for thermal and hygric uniformity. Its operational envelope spans –60°C to +150°C and 10–98% RH—with extended low-humidity capability (≤5% RH) achievable via optional desiccant-based dehumidification modules. This makes the RP-80U suitable for IEC 60068-2, ASTM D4332, ISO 188, and USP environmental stress testing protocols.

Key Features

• Energy-optimized design delivering up to 30% lower power consumption and 20% reduced water usage versus conventional chambers—validated under standard load conditions.
• Original French Tecumseh hermetic compressor ensuring long-term reliability, low vibration, and consistent refrigeration performance across extreme temperature transitions.
• SUS304 stainless-steel interior with seamless arc-welded corners and matte-finish surface treatment—resistant to corrosion, easy to clean, and compliant with ISO 14644-1 Class 8 cleanroom-compatible maintenance protocols.
• Intelligent safety architecture including high-sensitivity over-temperature, over-humidity, dry-run, and leakage detection—triggering automatic cut-off and audible/visual alarm within <100 ms.
• Integrated USB 2.0 interface supporting real-time data logging (temperature, humidity, setpoint, alarm status) to removable flash storage—enabling offline analysis and secure chain-of-custody transfer.
• RS-485/RS-232 communication ports compatible with IPC/SCADA systems—allowing centralized monitoring and control of up to 200+ units across distributed lab networks without dedicated cabling infrastructure.
• Double-layer heated observation window with embedded resistive heating elements—eliminating condensation and ensuring unobstructed visual access during low-temperature, high-humidity operation.
• Unidirectional centrifugal blower system with adjustable airflow distribution—minimizing thermal stratification and achieving ≤±2.0°C spatial temperature uniformity per IEC 60068-3-5.
• Physically isolated humidification circuit—steam generator, water reservoir, and control electronics are segregated from electrical compartments to prevent moisture ingress and ensure IP2X-rated insulation integrity.

Sample Compatibility & Compliance

The RP-80U accommodates diverse sample types—including polymer films, pharmaceutical blister packs, electronic assemblies, battery cells, and composite laminates—within its 400×500×400 mm test volume. Its chamber geometry and airflow design comply with ASTM E145-22 requirements for forced-air thermal exposure apparatuses. The unit meets CE marking directives (2014/30/EU EMC, 2014/35/EU LVD), conforms to RoHS 2011/65/EU material restrictions, and supports IQ/OQ/PQ validation documentation packages. When paired with LabCompanion’s validated firmware and audit-trail-enabled data management software, the system satisfies FDA 21 CFR Part 11 requirements for electronic records and signatures in regulated GxP environments.

Software & Data Management

The RP-80U operates via an embedded 7-inch TFT-LCD touchscreen controller running real-time Linux OS with deterministic task scheduling. It supports multi-step programmable profiles (up to 100 segments, 999 cycles), ramp/soak logic, and event-triggered actions (e.g., auto-start humidity reduction upon reaching –40°C). Raw sensor data (PT100 RTD for temperature, capacitive polymer sensor for RH) is sampled at 1 Hz and stored locally or exported via USB. Optional Ethernet module enables integration with LabCompanion’s CloudLink™ platform—providing remote access, automated report generation (PDF/CSV), and role-based user permissions aligned with ALCOA+ data integrity principles.

Applications

• Accelerated shelf-life testing of pharmaceuticals and medical devices per ICH Q1A(R3) guidelines.
• Thermal cycling and damp heat validation of automotive ECUs and PCBAs (ISO 16750-4).
• Moisture absorption/desorption kinetics studies for packaging materials (ASTM F1249).
• Low-temperature performance verification of lithium-ion batteries (SAE J2380).
• Environmental stress screening (ESS) of aerospace components under MIL-STD-810H Method 502.7.
• Stability testing of adhesives, coatings, and elastomers per ASTM D7702 and ISO 11341.

FAQ

What is the minimum achievable humidity level with the standard configuration?
Standard operation covers 10–98% RH; with the optional desiccant dehumidification module installed, the chamber achieves ≤5% RH at 25°C.
Does the RP-80U support validation documentation for GMP labs?
Yes—LabCompanion provides full IQ/OQ protocol templates, calibration certificates (NIST-traceable PT100 and RH sensors), and firmware validation reports compliant with Annex 11 and EU GMP Annex 15.
Can the USB data logger record both temperature and humidity simultaneously?
Yes—the embedded controller logs synchronized time-stamped values for both parameters at user-selectable intervals (1 sec to 60 min), with timestamp accuracy ±100 ms.
Is the chamber compatible with external data acquisition systems?
Absolutely—the RS-485 Modbus RTU interface allows bidirectional communication with PLCs, SCADA platforms, or custom Python/LabVIEW applications for real-time telemetry and closed-loop control.
What maintenance intervals are recommended for the refrigeration system?
Compressor oil and refrigerant integrity should be verified annually; filter-driers replaced every 24 months; full system leak check and charge verification required after any refrigerant service or major component replacement.
