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

Overview

The LabCompanion RP-80U is a precision-engineered programmable temperature and humidity controlled environmental test chamber designed for rigorous reliability testing, accelerated aging studies, and stability assessment in R&D laboratories, quality control departments, and manufacturing validation environments. It operates on the principle of Balanced Temperature and Humidity Control (BTHC), integrating independent yet synergistic refrigeration, heating, humidification, and air circulation subsystems to maintain highly stable and reproducible climatic conditions within its 400 × 500 × 400 mm working volume. The chamber supports ultra-low temperature operation down to –60°C and high-temperature exposure up to +150°C, coupled with a wide humidity range of 10–98% RH—extendable to ≤5% RH when equipped with an optional desiccant-based dehumidification module. Its BTHC architecture ensures minimal thermal lag and rapid dynamic response, enabling accurate simulation of real-world environmental stress profiles required for compliance with IEC 60068-2, MIL-STD-810, and ISO 16750 standards.

Key Features

• Energy-efficient design: Achieves up to 30% reduction in power consumption and 20% lower water usage versus conventional chambers, enabled by optimized heat exchanger geometry and variable-speed compressor modulation.
• HFC-based refrigerant system: Uses non-ozone-depleting, low-GWP hydrofluorocarbon refrigerant compliant with EU F-Gas Regulation (EU No 517/2014) and EPA SNAP program requirements.
• Hermetic French Tecumseh compressor: Factory-integrated, oil-lubricated hermetic unit delivering long-term reliability, low vibration, and consistent cooling performance across the full operating envelope.
• SUS304 stainless steel construction: Interior and exterior surfaces fabricated from brushed-finish 304-grade stainless steel, offering superior corrosion resistance, cleanability, and compatibility with GLP/GMP laboratory environments.
• Intelligent air distribution: Asymmetric centrifugal blower with adjustable vane diffusers ensures uniform airflow velocity and eliminates thermal/hygrometric dead zones—validated per ASTM E145 Annex A3.
• Dual-sensor redundancy: Independent Pt100 RTD sensors for temperature and capacitive polymer humidity sensors with NIST-traceable calibration certificates supplied standard.
• Integrated safety architecture: Multi-level protection includes over-temperature cutoff, over-humidity shutoff, phase failure detection, door open alarm, and emergency power disconnect—all logged with time-stamped event records.
• Front-accessible 18 L water reservoir: Modular stainless steel tank located at lower front panel for ergonomic refilling; features low-water level sensor and auto-shutdown function.

Sample Compatibility & Compliance

The RP-80U accommodates a broad spectrum of sample types—including electronic assemblies, polymer components, pharmaceutical packaging, automotive ECUs, and battery modules—without risk of condensation-induced degradation or material outgassing interference. Its internal chamber geometry and airflow pattern are validated to meet ISO 16750-4 (road vehicles), IEC 60068-2-1 (cold), IEC 60068-2-2 (dry heat), IEC 60068-2-30 (damp heat cyclic), and JEDEC JESD22-A110 (highly accelerated temperature and humidity stress test). Optional accessories—including pure water purification systems, CF card data loggers, and chemical desiccant dehumidifiers—support extended compliance with USP , FDA 21 CFR Part 11 (electronic records), and ISO/IEC 17025 audit requirements. All electrical components conform to CE, UL 61010-1, and RoHS directives.

Software & Data Management

The chamber is equipped with an embedded 7-inch color touchscreen controller running proprietary firmware compliant with IEC 62443-3-3 for industrial cybersecurity. It supports up to 100 programmable test profiles, each with 99 segments and loop capability. Real-time trend graphs display temperature/humidity deviation, energy consumption, and alarm status. Data logging occurs at user-selectable intervals (1 s to 60 min) and is exportable via USB 2.0 interface in CSV format—with timestamped, digitally signed files suitable for 21 CFR Part 11 audit trails when paired with LabCompanion’s optional validation package. RS-232/RS-485 ports enable integration into centralized SCADA networks supporting up to 200+ units per master node, facilitating remote monitoring and centralized calibration management across multi-site facilities.

Applications

• Accelerated life testing of lithium-ion batteries under thermal cycling and high-humidity storage conditions (per UN 38.3 Section 4.4).
• Stability studies for sterile medical device packaging per ISO 11607-1, including peel strength and seal integrity evaluation at defined温湿度 conditions.
• Environmental stress screening (ESS) of avionics hardware per DO-160G Section 4 (temperature) and Section 5 (humidity).
• Material compatibility testing of adhesives, coatings, and encapsulants exposed to combined thermal shock and moisture ingress.
• Calibration verification of hygrometers and thermometers using traceable reference conditions per ISO/IEC 17025 Clause 5.10.
• Pre-conditioning of test specimens prior to mechanical or electrical characterization per ASTM D618 and IPC-TM-650.

FAQ

What is the standard calibration certificate included with the RP-80U?
A factory-issued NIST-traceable calibration report is provided for both temperature and humidity sensors, covering three points across the operational range (–40°C, +25°C, +100°C and 35% RH, 65% RH, 95% RH) with uncertainty values stated per ISO/IEC 17025.
Can the RP-80U be validated for GMP environments?
Yes—the unit supports IQ/OQ/PQ documentation packages, including installation drawings, alarm logic diagrams, sensor mapping reports, and protocol templates aligned with Annex 15 and FDA guidance on process validation.
Is remote firmware update supported?
Firmware updates require local USB-based loading; however, diagnostic logs and configuration backups can be retrieved remotely via RS-485 SCADA polling.
What maintenance intervals are recommended?
Compressor oil inspection every 24 months; refrigerant leak check annually; humidity sensor recalibration every 12 months or after 500 operational hours—whichever occurs first.
Does the chamber support ramp-soak profiles with humidity hold steps?
Yes—fully programmable ramp rates (0.1–10°C/min, 0.1–5% RH/min) and soak durations (1 min to 999 h 59 min) are configurable independently for temperature and humidity axes.
