IEC 60068 Constant Temperature and Humidity Chamber

Product Description

The IEC 60068 Constant Temperature and Humidity Chamber, also known as a Programmable Environmental Test Chamber, simulates extreme climatic conditions ranging from -70°C to 150°C and 20% to 98% RH. This advanced testing equipment integrates heating, refrigeration, humidification, and dehumidification systems to evaluate material durability under dynamic or steady-state environments. By replicating natural climate cycles, it accelerates time-to-failure analysis, revealing potential defects in products within days that would otherwise take years to manifest. Ideal for R&D and quality control, it ensures compliance with international reliability standards.

Key Standards Compliance
This chamber meets rigorous global test protocols, including:

• IEC 60068-2-1 (Cold Tests)

• IEC 60068-2-2 (Dry Heat Tests)

• IEC 60068-2-78 (Damp Heat Steady State)

• IEC 60068-2-30 (Damp Heat Cyclic, 12h+12h)

• MIL-STD-810D (Low/High Temperature, Humidity)

• MIL-STD-202F (High Temperature Stress)

Applications
Widely used for reliability testing across industries:

• Electronics & Instruments: Circuit boards, sensors, batteries

• Automotive & Aerospace: Engine parts, composites, seals

• Consumer Goods: Plastics, rubber, textiles, footwear

• Construction & Metals: Coatings, alloys, building materials

• Custom Testing: Compatible with jigs for leather, footwear, and irregular specimens.

Core Features

1. Robust Construction: Stainless steel frame with fire-resistant PU foam insulation (Germany Bayer grade) for extreme thermal stability.

2. Smart Control: 7-inch touchscreen LCD with programmable settings (120 groups, 1,200 segments), PID auto-calibration, and SSR/SCR output.

3. Precision Sensors: PT100 humidity/temperature sensors + balanced T&H system for ±0.1°C accuracy.

4. Rapid Simulation: Unique air duct design and titanium alloy heaters ensure uniform temperature distribution (±2°C).

5. Safety Protections: Multi-layer safeguards for overheating, refrigeration failure, water supply, and power surges.

6. Visual Monitoring: Sweat-resistant viewing window for real-time observation.

7. Cyclic Testing: Programmable multi-stage climate loops (e.g., heat-cold-humidity transitions).

8. High/Low Flexibility: Doubles as a precision high-low temperature chamber (-70°C to 150°C) when humidity is disabled.

9. Automation: Auto-start, power-off memory, and alarm prompts.

10. Eco-Efficient: Low-energy refrigerant phase-change cooling via high-power compressors.

Functions

• Reliability Validation: Tests heat/cold/dry/wet resistance for product lifespans.

• Accelerated Aging: Compresses years of environmental exposure into days.

• Cyclic Stress Testing: Pre-programmed transitions between extreme conditions.

• Material Analysis: Identifies failures in polymers, coatings, and electronics.
