DRETOP THS-C100-I High-Low Temperature Environmental Test Chamber

Overview

The DRETOP THS-C100-I High-Low Temperature Environmental Test Chamber is an engineered precision system designed for controlled thermal stress evaluation of industrial components and materials under reproducible climatic conditions. Operating on the principle of forced-air convection with independent heating, cooling, and (optional) humidification subsystems, it enables precise simulation of extreme ambient environments—including steady-state high/low temperature exposure, thermal cycling, and—when equipped with humidity control—combined temperature-humidity stress profiles. The chamber conforms to core requirements of international environmental testing standards including IEC 60068-2-1 (Cold), IEC 60068-2-2 (Dry Heat), and ISO 16750-4 (Road Vehicles – Environmental Conditions). Its robust architecture supports validation protocols in R&D, quality assurance, and production line reliability screening across electronics, automotive electronics, LED modules, aerospace subassemblies, and medical device packaging.

Key Features

• 10.1-inch full-color capacitive touchscreen interface with bilingual (English/Chinese) language support, password-protected hierarchical access control (up to 10 user accounts with customizable permission levels)
• Programmable logic controller supporting up to 1,000 test programs, each containing up to 100 segments; flexible ramp/soak profiles with slope-controlled transitions
• Independent PID-controlled heating (nickel-chromium alloy heaters), cooling (imported hermetic compressor), and optional humidification systems—minimizing cross-interference and enhancing long-term stability
• Optimized airflow design featuring centrifugal forced convection fans and a fully insulated, double-wall stainless steel inner chamber (304 grade) with radius-rounded corners for uniform thermal distribution and easy cleaning
• Double-layer tempered glass observation window with integrated anti-frost heating element and LED interior lighting—enabling real-time visual monitoring without thermal disturbance
• High-integrity sealing using high-performance silicone rubber gaskets, maintaining chamber integrity across the full operating range (−60 °C to +120 °C) without deformation or adhesion loss
• Standard 50-mm-diameter test port (with removable plug) for live electrical, pneumatic, or signal feedthrough during operation
• Comprehensive safety suite: overtemperature cut-off, compressor/fan overload protection,漏电 (earth leakage) detection, automatic power recovery after outage, and audible/visual alarm triggers
• Energy-efficient operation with non-CFC refrigerant, adaptive compressor cycling, and intelligent standby mode

Sample Compatibility & Compliance

The THS-C100-I accommodates samples up to 500 × 400 × 500 mm (W × D × H) within its 100 L working volume. Two adjustable stainless steel shelves (load capacity: 15 kg per shelf, uniformly distributed) allow flexible sample arrangement. The chamber meets mechanical and thermal performance criteria referenced in ASTM D4332 (Standard Practice for Conditioning Containers, Packages, or Packaging Components for Testing), MIL-STD-810H Method 501.7 (High Temperature) and Method 502.7 (Low Temperature), and supports GLP-compliant data integrity when used with optional audit-trail-enabled software configurations. Optional RS485 or USB interfaces enable integration into laboratory-wide data acquisition networks compliant with FDA 21 CFR Part 11 requirements for electronic records and signatures.

Software & Data Management

Embedded firmware supports local data logging at user-defined intervals (minimum 1 s resolution), storing time-stamped temperature (and humidity, if configured) values internally for ≥30 days. Export options include CSV-formatted Excel-compatible files and native .DAT archives readable by DRETOP’s optional PC-based analysis suite. Remote management is enabled via built-in Ethernet/Wi-Fi connectivity: web-based HTML5 dashboard accessible from any modern browser; synchronized mobile app (iOS/Android) offering real-time parameter visualization, remote start/stop, alarm history review, and firmware updates. Concurrent access by up to five authenticated users is supported, with role-based permissions governing editing rights, report generation, and system configuration changes. All remote sessions are encrypted (TLS 1.2+), and audit logs record user actions, timestamps, and IP addresses for traceability.

Applications

• Thermal cycling qualification of PCBAs and semiconductor packages per JEDEC JESD22-A104
• Accelerated aging tests for polymer enclosures, adhesives, and conformal coatings
• Pre-conditioning of sensors and actuators prior to functional verification
• Validation of battery thermal management systems under extreme ambient extremes
• Environmental stress screening (ESS) of automotive ECUs and infotainment modules per AEC-Q200
• Stability assessment of pharmaceutical primary packaging under ICH Q1A(R2) guidelines (when humidity option installed)
• Calibration reference environment for thermocouple and RTD verification labs

FAQ

What is the standard warranty period for the THS-C100-I?
DRETOP provides a 24-month limited warranty covering parts and labor for defects in materials and workmanship under normal use conditions.

Can the chamber be integrated into a central LIMS or MES platform?
Yes—via Modbus TCP or custom API (available under NDA), enabling bidirectional communication with enterprise-level laboratory or manufacturing execution systems.

Is external humidity control available for this model?
The THS-C100-I base configuration is temperature-only; however, the THS-C100-II variant adds programmable humidity control (30–95% RH, ±3–5% RH accuracy) and is available upon request.

What electrical infrastructure is required for installation?
The unit operates on single-phase AC 220 V ±10%, 50 Hz, with a maximum input power of 4.5 kW. A dedicated circuit with 25 A breaker and proper grounding is mandatory.

Does the system support automated compliance reporting for ISO/IEC 17025 audits?
When paired with DRETOP’s optional TraceLink™ software module, the chamber generates PDF reports containing calibration certificates, uncertainty budgets, test logs with digital signatures, and equipment usage histories—fully aligned with ILAC P14 and ISO/IEC 17025:2017 documentation requirements.
