Labonce Labonce-800CH-2T Temperature and Humidity Controlled Chamber

Overview

The Labonce Labonce-800CH-2T Temperature and Humidity Controlled Chamber is an engineered environmental test system designed for precise, long-term simulation of temperature and humidity conditions in laboratory and quality assurance settings. It operates on a dual-climate control principle—combining refrigeration-based cooling, electric heating, and steam/humidification-driven moisture regulation—to maintain stable, repeatable environments across its full operating range of 15–60 °C and 20–95 %RH. With an internal volume of 800 L and dual-door access, the chamber accommodates large-scale samples, stacked test racks, or multi-point sensor arrays required for accelerated aging, stability testing, and material conditioning per international standards including GB/T 10586–2006. Its robust thermal architecture ensures minimal spatial gradient—validated by ≤2.0 °C temperature uniformity—and supports applications demanding strict environmental reproducibility, such as polymer aging, pharmaceutical packaging validation, and electronic component reliability assessment.

Key Features

• High-efficiency refrigeration circuit powered by an imported hermetic compressor, delivering low-noise operation (<65 dB(A)) and extended service life under continuous duty cycles.
• Advanced air circulation design featuring a rear-mounted centrifugal blower and optimized baffle-guided wind path, ensuring uniform distribution of conditioned air throughout the entire working chamber.
• Thermal insulation composed of high-density polyurethane foam (≥80 kg/m³) applied via high-pressure foaming—providing superior thermal resistance (U-value <0.35 W/m²·K) and minimizing condensation risk during low-humidity operation.
• Corrosion-resistant interior constructed entirely from mirror-polished AISI 304 stainless steel (thickness ≥1.2 mm), eliminating leaching, outgassing, or surface degradation during prolonged exposure to high-humidity or acidic test atmospheres.
• Programmable color touchscreen controller with real-time graphical display, 100-segment ramp-soak profiles, and built-in non-volatile memory supporting up to 10,000 data points; data export via USB flash drive in CSV format for traceability and audit compliance.
• Capacitive humidity sensing technology with factory calibration traceability, offering long-term stability (<±0.5 %RH/year drift) and immunity to condensation-induced hysteresis or salt contamination.
• Dual-level safety architecture: primary PID-controlled thermal regulation supplemented by independent mechanical overtemperature cutoff (adjustable 65–90 °C) and dry-heater protection circuitry with visual/audible alarm activation.

Sample Compatibility & Compliance

The Labonce-800CH-2T accommodates diverse sample configurations—including stacked trays, open shelving, sealed containers, and instrument-integrated monitoring probes—via its spacious 1200×490×1360 mm internal cavity and reinforced adjustable shelves (4 standard, load-rated to 25 kg/shelf). Dual outward-swinging doors with magnetic gaskets ensure rapid access without compromising seal integrity. The chamber meets the technical requirements of GB/T 10586–2006 for wet-heat testing equipment, including performance verification protocols for uniformity, fluctuation, and recovery time. While not certified to IEC 60068-2 or ISO 16750 by default, its control fidelity, sensor accuracy, and thermal repeatability make it suitable for pre-compliance screening and internal QA workflows aligned with GLP, ISO/IEC 17025, and FDA-regulated stability programs (ICH Q1A–Q1E).

Software & Data Management

The embedded controller firmware supports full-cycle logging at user-selectable intervals (1–600 seconds), storing time-stamped temperature, relative humidity, setpoint, and alarm status. All records include UTC timestamping and are exportable without proprietary software dependency. Optional RS485 Modbus RTU interface enables integration into centralized lab management systems (LIMS) or SCADA platforms for automated reporting. For regulated environments, optional 21 CFR Part 11-compliant audit trail modules (with electronic signature and role-based access control) are available upon request—supporting electronic record retention, change history, and operator accountability per GxP requirements.

Applications

• Stability testing of pharmaceuticals, medical devices, and active ingredients per ICH guidelines.
• Accelerated aging studies of polymers, adhesives, coatings, and composite materials.
• Environmental stress screening (ESS) of printed circuit boards (PCBs) and automotive electronics.
• Conditioning of hygroscopic materials (e.g., textiles, paper, wood composites) prior to mechanical or dimensional analysis.
• Calibration and verification of portable温湿度 meters, data loggers, and environmental sensors.
• Biological sample storage preconditioning and controlled-drying protocols for botanical or forensic specimens.

FAQ

What is the maximum ambient temperature at which the Labonce-800CH-2T can operate reliably?

The unit is rated for installation in rooms maintained between +5 °C and +35 °C. Operation above 35 °C may compromise cooling capacity and extend recovery times after door openings.
Can the chamber be validated for IQ/OQ/PQ protocols?

Yes—its stable control performance, documented sensor specifications, and data export capability support formal qualification. Validation templates and uncertainty budgets are provided upon request.
Is remote monitoring supported out of the box?

Standard configuration includes local touchscreen and USB export only. Ethernet or Wi-Fi connectivity requires optional communication module installation.
Are custom internal fixtures or shelf configurations available?

Labonce offers OEM engineering services for application-specific mounting rails, perforated trays, and cable management kits—subject to minimum order quantity.
Does the chamber comply with CE or UL safety directives?

The Labonce-800CH-2T conforms to GB 4793.1 (equivalent to IEC 61010-1) for electrical safety. CE marking is available for export orders with additional EMC and RoHS documentation.
