DRETOP THS-C150 High-Low Temperature & Humidity Environmental Test Chamber

Overview

The DRETOP THS-C150 High-Low Temperature & Humidity Environmental Test Chamber is an engineered environmental simulation system designed for rigorous reliability validation of industrial components and finished products under controlled thermal and hygrothermal stress conditions. Based on the principles of forced-air convection, precision PID-controlled heating/cooling, and saturated steam humidification, the chamber replicates standardized climatic profiles—including steady-state high/low temperature, constant humidity, and cyclic temperature-humidity transitions—as defined in international test standards such as IEC 60068-2, MIL-STD-810, and GB/T 2423. Its −60 °C to +120 °C operational range and 20–98% RH humidity capability enable comprehensive evaluation of material integrity, dimensional stability, electrical performance, and sealing efficacy across diverse product lifecycles.

Key Features

• Full-color 7-inch touchscreen controller with multilingual UI (English/Chinese), password-protected hierarchical access (admin/operator/user), and audit-trail-capable operation logging.
• Programmable logic supporting up to 1000 user-defined test cycles, each containing 100 programmable segments; enables precise ramp/soak/humidity-sweep profiles with slope control and time-scheduled lighting or power cycling.
• Independent dual-loop control architecture for temperature and humidity—minimizing cross-interference and enhancing long-term repeatability and energy efficiency.
• Optimized air circulation system featuring high-efficiency centrifugal blower, nickel-chromium alloy heating elements, and refrigerant circuit with imported hermetic compressor (R404A/R23 cascade configuration for −60 °C capability).
• Double-layer tempered glass observation window with anti-frost electric heating and LED interior illumination—prevents condensation-induced sample contamination while enabling real-time visual monitoring.
• Stainless steel 304 inner chamber with radius-rounded corners, removable adjustable shelves, and silicone rubber door gasket ensuring >95% chamber airtightness across operating temperature extremes.
• Comprehensive safety suite including over-temperature cut-off, compressor/fan overload protection, leakage current detection, auto-restart after power interruption, and audible/visual alarm signaling.

Sample Compatibility & Compliance

The THS-C150 accommodates electronic assemblies, automotive ECUs, LED modules, PCBs, polymer enclosures, battery packs, and medical device housings—up to 150 L internal volume (500 × 500 × 600 mm). A standard Ø50 mm test port enables live signal/power feedthrough for in-situ functional testing. The chamber conforms to critical regulatory and industry-standard test methodologies, including: IEC 60068-2-1 (Cold), IEC 60068-2-2 (Dry Heat), IEC 60068-2-30 (Cyclic Damp Heat), IEC 60068-2-78 (Steady-State Damp Heat), MIL-STD-810H Method 502.7 (Low Temperature), Method 501.7 (High Temperature), and Method 507.6 (Humidity). It supports GLP-compliant data recording when integrated with optional RS485/USB interfaces and validated software platforms.

Software & Data Management

Equipped with embedded firmware supporting local data logging (≥30 days at 1-minute intervals), the THS-C150 exports timestamped temperature/humidity datasets in native CSV format compatible with Excel, MATLAB, and statistical process control (SPC) tools. Optional cloud connectivity enables remote supervision via web browser, iOS/Android mobile app, or Windows desktop client—supporting concurrent multi-user access with role-based permissions (administrator, technician, viewer). All remote operations are logged with user ID, timestamp, and action type—meeting FDA 21 CFR Part 11 requirements for electronic records and signatures when deployed with validated server infrastructure.

Applications

• Accelerated aging and failure mode analysis of consumer electronics subjected to seasonal climate variations.
• Thermal shock screening of solder joints, conformal coatings, and adhesive bonds in automotive electronics.
• Validation of IP-rated ingress protection under combined high-humidity and elevated-temperature exposure.
• Qualification testing of lithium-ion battery modules per UN 38.3 Section 4.4 (Thermal Cycling) and IEC 62133.
• Material compatibility assessment for packaging films, gaskets, and elastomers exposed to tropical or arctic storage conditions.
• Pre-compliance verification for CE, FCC, and CCC certification pathways requiring environmental robustness evidence.

FAQ

What is the maximum allowable sample load volume inside the THS-C150 chamber?
The recommended maximum sample volume is 30% of the internal chamber volume (i.e., ≤45 L) to preserve specified temperature uniformity (≤2 °C) and airflow dynamics.
Does the THS-C150 support automated data export to LIMS or MES systems?
Yes—via optional RS485 Modbus RTU or USB virtual COM port interface, raw sensor data can be streamed in real time to third-party laboratory information management systems (LIMS) or manufacturing execution systems (MES) using configurable polling intervals.
Is calibration documentation provided with the unit?
Each THS-C150 ships with a factory calibration certificate traceable to NIM (National Institute of Metrology, China) for temperature and humidity sensors, valid for 12 months from date of shipment.
Can the chamber operate continuously for extended qualification tests (e.g., 1000-hour HALT)?
Yes—the system is rated for unattended 24/7 operation with redundant thermal protection, compressor duty-cycle optimization, and predictive maintenance alerts based on cumulative runtime and fault history.
What humidity control method is employed, and how is condensation prevented on samples?
Steam humidification via stainless steel immersion heater ensures stable RH generation; the heated observation window and chamber wall temperature control minimize dew-point differentials, preventing condensate formation on test specimens during cooling or high-humidity phases.
