Labonce Labonce-1000TH-T Temperature and Humidity Controlled Environmental Test Chamber

Overview

The Labonce Labonce-1000TH-T is a high-capacity, precision-engineered temperature and humidity controlled environmental test chamber designed for rigorous stability testing, accelerated aging studies, and long-term reliability validation in R&D laboratories, quality control departments, and manufacturing facilities. Built upon the principles of forced-air convection and closed-loop PID-controlled thermohygrometric regulation, the chamber maintains stable, repeatable conditions across its 1000 L internal volume—enabling uniform exposure of large or multi-component samples to defined climatic stress profiles. Its operational envelope spans 0–100 °C and 20–95 %RH, meeting the physical parameter requirements specified in GB/T 10586–2006 for damp heat test chambers, and serving as a technically compliant platform for preliminary assessments aligned with broader international frameworks including IEC 60068-2-30 (damp heat, cyclic) and ISO 16750-4 (road vehicles – environmental conditions).

Key Features

• Advanced air distribution system engineered for superior thermal and hygrometric uniformity—validated at ≤2.0 °C temperature uniformity and <±3 %RH humidity fluctuation across the working volume;
• High-density polyurethane foam insulation (≥100 mm thick) minimizing thermal bridging and ensuring low energy consumption and stable boundary conditions during extended tests;
• Corrosion-resistant mirror-finish 304 stainless steel interior chamber walls and floor—non-porous, non-shedding, and compatible with cleaning protocols required under GLP and GMP environments;
• Imported hermetically sealed refrigeration compressor delivering consistent cooling performance with low acoustic emission (<65 dB(A)) and extended service life;
• Programmable 7-inch full-color touchscreen controller supporting up to 99 programmable segments per cycle, ramp/soak profiles, and real-time monitoring of chamber status, setpoints, and deviations;
• Dual independent safety systems: mechanical over-temperature cut-off (separate from main controller) and dry-burn protection for humidifier elements—both triggering visual and audible alarms;
• Calibration-ready architecture with accessible sensor mounting points and documented traceability pathways for field verification of temperature and humidity sensors.

Sample Compatibility & Compliance

The Labonce-1000TH-T accommodates diverse sample configurations—including stacked electronics enclosures, automotive subassemblies, pharmaceutical packaging trays, and polymer specimens—via its spacious 1400×510×1400 mm internal cavity and four adjustable 304 stainless steel shelves (load-rated to 25 kg per shelf). A 50 mm diameter test port with silicone rubber plug enables external cabling without compromising chamber integrity. All materials in contact with the test environment conform to RoHS Directive 2011/65/EU. While the chamber itself is not certified to UL, CSA, or CE for hazardous location use, its construction and control logic support integration into validated processes compliant with ISO/IEC 17025, FDA 21 CFR Part 11 (when paired with audit-trail-enabled software), and Annex 11 (Computerized Systems) requirements when deployed with documented IQ/OQ/PQ protocols.

Software & Data Management

Data acquisition is handled internally by the embedded controller’s non-volatile memory, recording timestamped temperature and humidity values at user-defined intervals (1–600 seconds). Historical logs are exportable via standard USB 2.0 interface to FAT32-formatted drives in CSV format—compatible with Microsoft Excel, MATLAB, and LIMS platforms. Optional printer integration supports on-demand hardcopy reporting of active cycles and alarm events. For enterprise-scale deployment, Labonce provides optional RS485 Modbus RTU communication capability (upon request), enabling centralized monitoring via SCADA or MES systems. All stored data retains metadata including operator ID (if configured), program name, start/stop timestamps, and deviation flags—supporting basic ALCOA+ data integrity principles.

Applications

• Stability testing of pharmaceutical primary and secondary packaging under ICH Q1A(R2) recommended conditions (e.g., 40 °C/75 %RH long-term);
• Environmental stress screening (ESS) of printed circuit board assemblies prior to burn-in;
• Accelerated corrosion testing of coated metal components per ASTM D2247;
• Moisture absorption/desorption kinetics studies for hygroscopic polymers and composites;
• Validation of HVAC system performance in cleanroom mock-ups or equipment enclosures;
• Pre-compliance evaluation for automotive electronics per ISO 16750-4 (high-humidity soak and cyclic tests).

FAQ

What standards does the Labonce-1000TH-T comply with?
It is designed and verified per GB/T 10586–2006, the Chinese national standard for damp heat test chambers. Its performance parameters align with key sections of IEC 60068-2-30 and ISO 16750-4, though formal certification to those standards requires third-party validation.
Can the chamber perform temperature-humidity cycling?
Yes—the programmable controller supports multi-step ramp-and-soak sequences, enabling fully automated cyclic profiles (e.g., 25 °C/40 %RH → 60 °C/90 %RH → 25 °C/40 %RH) with dwell times configurable from 1 minute to 999 hours.
Is the humidity sensor calibrated and replaceable?
The imported capacitive RH sensor is factory-calibrated with a certificate of conformance. It is field-replaceable using standard Torx tools; recalibration is supported using NIST-traceable reference hygrometers.
What is the maximum load capacity for continuous operation at 85 °C/85 %RH?
At this demanding condition, the recommended total thermal load (including samples, fixtures, and internal airflow resistance) should not exceed 1.2 kW to maintain specified uniformity and stability margins.
Does the unit support remote monitoring or network connectivity?
Standard configuration includes USB data export only. Ethernet or Wi-Fi connectivity is not built-in but can be implemented externally via industrial protocol gateways using the available RS485 Modbus interface (optional accessory).
