Home Products Humidity Chamber

Humidity Chambers are precision environmental testing systems built to simultaneously control both temperature and humidity, enabling accurate simulation of real-world climatic conditions. Used across industries to validate product reliability, material stability, and packaging integrity under combined thermal and moisture stress, these chambers are essential for compliance with international testing standards including IEC, ASTM, and MIL-STD.

Some Essential Features of Humidity Chambers

Temperature & Humidity Control

  • Wide temperature range: -70°C to +180°C.
  • Humidity range: 10–98% RH with ±1–2% RH accuracy.
  • Temperature precision: ±0.5–1°C for stable, repeatable tests.

Programmable Controllers

  • Touchscreen / digital interface with intuitive controls.
  • Storage for complex, multi-step test cycle profiles.
  • Connectivity via Ethernet, USB, and RS-232.

Uniform Airflow System

  • Forced-air circulation for consistent temperature and humidity distribution.
  • Minimizes hot/cold spots and humidity gradients across the test volume.

Construction & Insulation

  • Stainless steel interior for corrosion resistance and easy cleaning.
  • High-density polyurethane foam insulation for thermal efficiency.
  • Powder-coated exterior casing resistant to corrosion.

Safety Features

  • Independent over-temperature protection thermostat.
  • Humidity sensor alarms for out-of-range detection.
  • Door interlocks and emergency shutoff system.

Water Supply System

  • Built-in or external reservoir with demineralized water option.
  • Integrated humidifier and dehumidifier for precise RH control.
  • Low-water level warning and auto-shutoff protection.

Observation Window & Lighting

  • Double-glazed anti-fog observation window for clear visibility.
  • Interior LED lighting for monitoring without opening the door.
  • Cable access ports for external sensor integration.
