  • Models & Specification

A humidity chamber (also called a climatic or environmental test chamber) is used to simulate humidity and temperature conditions for testing products or materials under controlled environments.

Some Essential Features of Humidity Chamber

These chambers are designed for reliability, accuracy, and long-term durability, with several key features:

  • Temperature & Humidity Control

    • Wide temperature range (typically -70°C to +180°C).
    • Relative humidity range from 20% to 98% RH.
    • Precision control with tight tolerances (±1–2% RH, ±0.5–1°C).
  • Programmable Controllers

    • Touchscreen interface or digital controller.
    • Ability to create and store complex test cycles.
    • Ethernet/USB/RS-232 connectivity for remote monitoring or data logging.
  • Uniform Airflow System

    • Ensures consistent temperature and humidity throughout the chamber.
    • Minimizes hot/cold spots for accurate results.
  • Construction & Insulation

    • Corrosion-resistant stainless steel interior.
    • High-quality insulation for energy efficiency and stable conditions.
  • Safety Features

    • Over-temperature protection.
    • Humidity water level sensors.
    • Alarm systems for system failures.
  • Water Supply System

    • Built-in or external water reservoir.
    • Options for demineralized or distilled water connections.
    • Humidifier and dehumidifier components.
  • Observation Window & Lighting

    • Double-glazed observation window.
    • Interior lights for viewing without opening the door.
  • Data Logging & Connectivity

    • Real-time monitoring.
    • Exportable test reports.
    • Integration with laboratory information systems (LIMS).
  • Optional Accessories

    • Bench top models for small samples.
    • Walk-in chambers for large equipment or batch testing.
  • Size & Capacity Options

    • Shelves, cable ports, chart recorders.
    • Vibration, altitude, or UV exposure add-ons.

Key Applications of Humidity Chambers

These chambers are used across various sectors such as:

  • Electronics & Semiconductors
    Purpose: Assess reliability under high humidity.
    Tests: Corrosion of solder joints, insulation resistance, PCB delamination.
    Example: Testing smartphones for tropical climates.

  • Pharmaceutical & Medical Devices
    Purpose: Ensure product stability and efficacy.
    Tests: ICH stability testing, packaging integrity.
    Example: Shelf life testing for tablets in blister packs.

  • Automotive Industry
    Purpose: Evaluate durability of parts exposed to environmental conditions.
    Tests: Fogging, corrosion, moisture ingress.
    Example: Testing dashboards, wiring harnesses, sensors.

  • Aerospace & Defense
    Purpose: Simulate harsh environments during flight or storage.
    Tests: Moisture resistance, material expansion, avionics reliability.
    Example: Condensation resistance of cockpit instruments.

  • Textile & Leather
    Purpose: Assess color fastness, shrinkage, and mildew resistance.
    Tests: Aging under high humidity, drying performance.
    Example: Testing sportswear for tropical usage.

  • Packaging Industry
    Purpose: Evaluate how packaging holds up in humid conditions.
    Tests: Barrier performance, label adhesion.
    Example: Testing vacuum-sealed food packaging.

  • Construction Materials
    Purpose: Determine longevity and mold resistance.
    Tests: Swelling, warping, and delamination under moisture.
    Example: Testing wood panels or insulation foam.

  • Consumer Goods & Appliances
    Purpose: Check performance and safety in high-humidity environments.
    Tests: Corrosion, condensation inside products.
    Example: Testing electric toothbrushes or coffee machines.
