Labonce Labonce-150TH-T Temperature and Humidity Controlled Environmental Test Chamber

Overview

The Labonce Labonce-150TH-T is a precision-engineered temperature and humidity controlled environmental test chamber designed for rigorous stability testing, accelerated aging studies, and long-term reliability evaluation of materials, electronic components, pharmaceutical packaging, and polymer-based products. Operating on the fundamental principles of forced-air convection and closed-loop PID-controlled refrigeration/dehumidification and steam/humidification systems, the chamber maintains stable thermal and hygrometric conditions across its 150 L working volume. Its architecture adheres to the technical requirements defined in GB/T 10586–2006 — China’s national standard for damp heat test chambers — ensuring metrological traceability and repeatability under regulated laboratory and quality assurance environments. The unit is not intended for sterile or cleanroom applications but is optimized for industrial QC labs, R&D facilities, and contract testing organizations requiring ISO/IEC 17025-aligned environmental simulation capability.

Key Features

• High-fidelity climate control: Achieves ±0.5 °C temperature fluctuation and ≤2.0 °C spatial uniformity across the chamber volume; humidity control accuracy meets 75 %RH) and <±5 %RH (at ≤75 %RH), validated per GB/T 10586–2006 calibration protocols.
• Optimized air distribution: A redesigned laminar airflow duct system ensures consistent temperature and humidity distribution at all load positions—critical for multi-sample comparative testing and ICH Q1A(R2)-aligned stability protocols.
• Dual-layer thermal integrity: 100 mm thick high-density polyurethane foam insulation (thermal conductivity ≤0.022 W/m·K) minimizes energy loss and suppresses external ambient influence, enabling stable operation within ambient temperatures of +5 °C to +35 °C.
• Corrosion-resistant chamber construction: Interior surfaces are fabricated from electropolished AISI 304 stainless steel (mirror finish, Ra ≤0.4 µm), eliminating particulate shedding and facilitating residue-free cleaning between test cycles.
• Robust refrigeration and humidification subsystems: Equipped with an imported hermetically sealed compressor and a dedicated steam generator with proportional-integral-derivative (PID) modulation, delivering low-noise (<62 dB(A)), high-cycle-life operation.
• Intuitive programmable controller: 7-inch full-color touchscreen interface supports up to 99 programmable segments, ramp-soak profiles, real-time trend visualization, and password-protected parameter locking—compatible with GLP-compliant audit trail documentation when paired with optional data export logs.

Sample Compatibility & Compliance

The Labonce-150TH-T accommodates a wide range of non-volatile, non-explosive samples—including printed circuit boards, lithium-ion battery cells, medical device packaging, tablet blister packs, and elastomeric seals—within its 600 × 405 × 620 mm internal cavity. Standard features include a 50 mm diameter test port with silicone rubber plug, four adjustable 304 stainless steel shelves (3 included, 3 additional optional), heavy-duty casters with locking brakes, and a reinforced double-gasketed door. All materials in direct contact with the test environment comply with RoHS Directive 2011/65/EU. While not certified to IEC 60068-2 or MIL-STD-810G out-of-the-box, the chamber’s performance envelope satisfies prerequisite conditions for user-conducted validation per ISO 17025 Clause 5.10 and ASTM E2234–22 Annex A1 (Environmental Chamber Qualification). Calibration certificates traceable to NIM (National Institute of Metrology, China) are available upon request.

Software & Data Management

The embedded controller provides native data logging at user-selectable intervals (1–60 min), storing up to 12 months of timestamped temperature and humidity records internally. Data export is supported via standard USB 2.0 interface—no proprietary drivers required—with CSV-formatted files compatible with Excel, MATLAB, JMP, and LIMS platforms. Optional firmware upgrades enable Modbus RTU (RS-485) communication for integration into centralized building management systems (BMS) or SCADA networks. For regulated environments, the system supports manual generation of electronic records compliant with FDA 21 CFR Part 11 requirements when used in conjunction with validated third-party software for electronic signature, audit trail, and role-based access control.

Applications

• Pharmaceutical stability testing per ICH Q1A(R2), including long-term (25 °C/60 %RH) and accelerated (40 °C/75 %RH) conditions.
• Electronics reliability assessment: thermal cycling, moisture sensitivity level (MSL) pre-conditioning, and solder paste shelf-life verification.
• Polymer and composite material aging: evaluating dimensional stability, tensile strength retention, and hydrolytic degradation kinetics.
• Automotive component validation: interior trim fogging resistance, adhesive bond durability, and gasket compression set under cyclic humidity exposure.
• Quality assurance for food packaging: barrier property verification under tropical (30 °C/90 %RH) and temperate (23 °C/50 %RH) storage simulations.

FAQ

What standards does the Labonce-150TH-T comply with?
It conforms to GB/T 10586–2006 for damp heat test chamber performance. Additional validation to ISO 17025, ASTM E2234, or ICH Q1A(R2) must be performed by the end user.
Can the chamber perform temperature-humidity cycling tests?
Yes—the programmable controller supports multi-step ramp-and-soak profiles, enabling automated transitions between temperature and humidity setpoints for IEC 60068-2-30-type tests.
Is remote monitoring supported?
Native Ethernet or Wi-Fi connectivity is not built-in; however, USB data export and optional RS-485 Modbus output allow integration with external SCADA or cloud-based monitoring platforms.
What maintenance is required for the humidity sensor?
The imported capacitive RH sensor is drift-compensated and requires no routine recalibration or replacement under normal operating conditions (typical service life >5 years).
Are calibration services available?
Yes—NIM-traceable calibration certificates for temperature and humidity sensors can be provided at time of shipment or during annual preventive maintenance visits.
