Labonce Labonce-500CH-T Temperature and Humidity Controlled Chamber

Overview

The Labonce Labonce-500CH-T is a precision-engineered temperature and humidity controlled chamber designed for long-term stability testing, accelerated aging studies, material conditioning, and environmental simulation in R&D laboratories, quality control departments, and regulatory-compliant manufacturing facilities. Operating on the principle of forced-air convection with dual independent control loops for temperature and relative humidity, the chamber maintains highly reproducible test conditions across its 500 L working volume. Its design adheres strictly to GB/T 10586–2006 — the Chinese national standard for technical requirements of damp heat test chambers — ensuring metrological traceability and performance validation under defined environmental constraints. The unit is intended for use in ambient environments between +5 °C and +35 °C, making it suitable for integration into climate-controlled laboratory spaces without auxiliary cooling infrastructure.

Key Features

• Forced-air circulation system with optimized duct geometry ensures uniform distribution of conditioned air, achieving ≤2.0 °C temperature uniformity and <±3 %RH humidity uniformity throughout the working chamber.
• High-density polyurethane foam insulation (≥100 mm thick) minimizes thermal bridging and reduces energy consumption while maintaining stable internal conditions during extended operation cycles.
• Interior constructed entirely from electropolished AISI 304 stainless steel with mirror finish—non-porous, corrosion-resistant, and compliant with ISO 14644-1 Class 8 cleanroom-compatible cleaning protocols.
• Imported hermetic refrigeration compressor delivers consistent cooling capacity across the full 15–60 °C operating range, with low acoustic emission (25,000 hours MTBF).
• Capacitive humidity sensor with factory calibration certificate provides high-resolution RH measurement (0.1 %RH resolution), minimal long-term drift (<0.5 %RH/year), and zero maintenance requirement over typical service intervals.
• Programmable 7-inch color touchscreen controller supports up to 100 segments per program, real-time trend graphing, event logging, and data export via USB flash drive in CSV format.
• Dual-level safety architecture includes independent mechanical over-temperature cut-off (adjustable up to 80 °C), dry-burn protection for humidifier elements, and audible/visual alarm activation upon fault detection.

Sample Compatibility & Compliance

The Labonce-500CH-T accommodates a broad spectrum of sample types—including polymer films, pharmaceutical packaging, electronic components, coated substrates, and biological reference materials—without risk of cross-contamination or surface degradation. Its stainless-steel interior and absence of volatile organic outgassing sources meet material compatibility requirements for ICH Q1A(R2), ASTM D4332, and ISO 4892-2 test protocols. While not certified to UL/CSA or CE for North American or EU markets, the chamber’s construction and control architecture support alignment with GLP and GMP documentation practices, including audit-ready event logs and user-accessible calibration history. Optional printer integration enables hard-copy generation of test reports meeting internal SOPs and FDA 21 CFR Part 11 record retention guidelines when paired with validated software configurations.

Software & Data Management

The embedded controller firmware implements non-volatile memory storage for ≥10,000 data points (timestamped temperature/humidity readings at user-defined intervals down to 1-minute resolution). All logged data are exportable via USB interface in plain-text CSV format compatible with Microsoft Excel, MATLAB, and LIMS platforms. No proprietary software installation is required for basic data retrieval; advanced users may configure remote monitoring via optional RS485/Modbus RTU interface (subject to hardware add-on). Audit trails include operator ID, parameter changes, alarm events, and power interruption timestamps—enabling full traceability for internal quality audits and regulatory inspections.

Applications

• Stability testing of medical devices per ISO 11607-1 and packaging validation per ASTM F1980.
• Accelerated aging of lithium-ion battery cells and separators under controlled hygrothermal stress.
• Conditioning of composite materials prior to tensile, flexural, or impact testing (ASTM D618).
• Pre-humidification of filter media and membrane samples before permeability or bubble point analysis.
• Environmental stress screening (ESS) of printed circuit boards and solder-joint reliability assessment.
• Calibration verification of portable hygrometers and thermometers using NIST-traceable reference conditions.

FAQ

What is the maximum allowable ambient temperature for reliable operation?
The chamber requires an ambient environment between +5 °C and +35 °C. Operation above 35 °C may impair condenser efficiency and compromise humidity recovery time.
Can the chamber maintain 20 %RH at 60 °C?
Yes—the specified humidity range of 20–95 %RH is fully operational across the entire temperature span of 15–60 °C, verified per GB/T 10586–2006 Annex B.
Is the touchscreen controller password-protected?
Yes—three-tier access control (Operator, Engineer, Administrator) is implemented with configurable password policies and session timeout settings.
How many test ports are included as standard equipment?
One 50 mm diameter test port with silicone rubber plug is supplied; additional ports can be installed at the time of order upon request.
Does the unit comply with electromagnetic compatibility (EMC) standards?
The Labonce-500CH-T meets EN 61326-1:2013 for industrial environments regarding emissions and immunity; full CE marking is available upon request with additional conformity documentation.
