Overview

The KS-TH Series Rapid Temperature and Humidity Cycling Chamber is an engineered environmental simulation system designed for precise, repeatable evaluation of product reliability under dynamic thermal and hygrothermal stress conditions. Based on forced-air convection with independent dual-loop PID-controlled refrigeration and steam-based humidification systems, the chamber delivers controlled transitions between extreme temperature and humidity states—enabling accelerated life testing, qualification validation, and failure mode analysis per internationally recognized environmental test protocols. Its architecture supports both steady-state and cyclic profiles, including temperature-only, humidity-only, and combined temperature-humidity ramps, making it suitable for validating electronics, automotive components, aerospace subsystems, medical devices, and packaging materials against real-world operational and storage environments.

Key Features

• High-precision dual-channel control: Independent regulation of temperature (±0.5°C fluctuation) and relative humidity (±2–3% RH deviation) ensures metrological integrity across all test phases.
• Robust chamber construction: Inner chamber fabricated from SUS304 stainless steel mirror-finish panels; outer shell formed from A3 steel with electrostatic powder coating for corrosion resistance and long-term dimensional stability.
• Optimized airflow design: Horizontal laminar air distribution with adjustable vane diffusers guarantees uniform thermal/hygrometric exposure throughout the working volume—verified per GB/T 5170.2–1996 calibration requirements.
• Integrated observation and access: Large double-layer heated anti-fog viewing window with internal LED illumination enables real-time visual monitoring without thermal disturbance; Ø50 mm test port allows external signal/power feedthrough with optional sealing gaskets.
• Customization-ready platform: Modular refrigeration, heating, and humidification subsystems support non-standard configurations—including extended low-temperature capability down to –70°C, high-humidity saturation up to 98% RH, or bespoke internal geometries per customer specifications.

Sample Compatibility & Compliance

The KS-TH chamber accommodates a broad spectrum of sample types—from PCB assemblies and battery modules to polymer housings and sealed enclosures—without requiring internal fixturing modifications. Its validated performance envelope meets mandatory compliance criteria for IEC/EN 60068-2 series, MIL-STD-810H (Method 502.7, 507.6), and ISO 16750-4 (road vehicles). All standard configurations are certified to GB/T 2423.1–2001 (cold), GB/T 2423.2–2001 (dry heat), GB/T 2423.3–2001 (damp heat, steady state), and GB/T 2423.4–2001 (damp heat, cyclic), with traceable calibration documentation available upon request. Optional audit-ready data logging satisfies GLP/GMP-aligned record retention requirements, including timestamped parameter history and operator identification.

Software & Data Management

Equipped with a 7-inch color touchscreen HMI running embedded real-time OS, the chamber supports multi-segment programmable profiles with up to 99 cycles, dwell times, ramp rates, and conditional branching logic. Data is logged at user-selectable intervals (1 s to 60 min) and exportable via USB or Ethernet to CSV or Excel-compatible formats. Optional PC-based software provides advanced visualization (trend charts, deviation overlays), automated report generation (PDF/HTML), and secure user-level access control (admin/operator/guest). For regulated environments, optional 21 CFR Part 11-compliant firmware adds electronic signatures, audit trails, and data integrity safeguards—fully compatible with laboratory information management systems (LIMS).

Applications

• Electronics reliability screening: Thermal cycling of semiconductors, connectors, and solder joints per JEDEC JESD22-A104 and IPC-9701.
• Automotive component validation: Climate stress testing of ECUs, sensors, and infotainment systems per ISO 16750-4 and GMW14872.
• Aerospace hardware qualification: Environmental stress screening (ESS) of avionics per RTCA DO-160 Section 4 and SAE ARP4754A.
• Medical device verification: Biocompatibility and shelf-life assessment under accelerated aging conditions per ISO 11607-1 and ASTM F1980.
• Materials science research: Hygrothermal aging studies of composites, adhesives, and coatings in controlled degradation trials.

FAQ

What standards does this chamber comply with?

It meets GB/T 2423.1–2001, GB/T 2423.2–2001, GB/T 2423.3–2001, GB/T 2423.4–2001, GB/T 10592–1989, GB/T 5170.2–1996, GJB 150.3–1986, GJB 150.4–1986, and GJB 150.9–1986. Equivalent compliance with IEC 60068-2 and MIL-STD-810H can be verified through third-party calibration reports.

Can the chamber perform non-standard test profiles?

Yes—custom ramp rates, dwell sequences, humidity hold points, and combined thermal/hygrometric transients can be programmed directly via the HMI or imported from external profile files.

Is remote monitoring supported?

Standard Ethernet interface enables integration with facility SCADA systems or cloud-based monitoring platforms using Modbus TCP or HTTP API protocols.

What maintenance is required?

Routine tasks include quarterly condensate drain inspection, annual refrigerant pressure verification, biannual humidifier tank cleaning, and semi-annual calibration of temperature/humidity sensors per ISO/IEC 17025 guidelines.

Does the system support GLP/GMP documentation?

With optional 21 CFR Part 11 firmware, full audit trail, electronic signature, and tamper-evident data archiving are enabled—suitable for FDA-regulated laboratories and ISO 13485-certified medical device manufacturers.
