Humidity Chamber - Conditioning Chamber

What is a Humidity Chamber?

A Humidity Chamber, also known as a Conditioning Chamber, is a specialized environmental test equipment used to replicate humidity and temperature conditions in a controlled laboratory setting. It allows manufacturers and researchers to expose their materials, components, and products to specific relative humidity (RH) levels and temperature profiles to assess their performance, reliability, and lifespan in varying environmental conditions.

Humidity testing plays a critical role in industries such as automotive, packaging, electronics, textiles, plastics, and pharmaceuticals, where moisture-sensitive materials are used. With changing global climate conditions and the need for long-lasting products, humidity testing has become essential for ensuring product stability, quality, and shelf life.

Most chambers, including the one manufactured by Pacorr, conform to international standards such as:

• ASTM D1776: Standard Practice for Conditioning and Testing Textiles
• ISO 2233: Packaging - Complete, Filled Transport Packages - Conditioning for Testing
• IEC 60068-2-78: Environmental Testing - Test Cab: Damp heat, steady state

These standards define methods for conditioning and maintaining precise environmental parameters to ensure accurate test results. The chamber comes equipped with digital controls, data logging, and safety mechanisms, making it ideal for both cyclic and steady-state humidity testing.

Pacorr's chamber ensures uniform distribution of humidity and temperature using automated controllers, stainless steel inner chambers, and forced air circulation technology. This helps simulate tropical, coastal, or wet weather environments for accurate product evaluation.

Applications of Humidity/Conditioning Chamber

Humidity chambers are extensively used across multiple sectors to determine the moisture resistance of different products and materials. Some of the key applications include:

• Electronics Industry: To test PCB boards, sensors, and semiconductors for corrosion, short-circuits, and insulation breakdown under humid conditions.
• Packaging and Paper: Evaluate the durability of corrugated boxes, adhesives, labels, and wraps exposed to varying humidity during storage or shipping.
• Pharmaceuticals: Stability testing of tablets, capsules, and packaging under moisture exposure.
• Textiles: Assessing shrinkage, color fastness, and mechanical performance after humidity conditioning.
• Automotive Components: Testing the resistance of rubber, plastics, and composite parts used in interior and under-the-hood applications.
• Paints and Coatings: Checking adhesion, blistering, and other surface defects in high-humidity conditions.

Humidity chambers are also used in research institutes, quality inspection labs, and production units to meet compliance and product certification requirements.

Working Principle of Humidity Chamber

The working principle of a humidity chamber is based on the generation and control of temperature and humidity inside a closed, insulated chamber. Here's how it functions:

• Humidity Generation: The chamber uses a water reservoir and heating system to generate steam. This steam is circulated into the chamber through a fan-assisted mechanism to distribute moisture evenly.
• Temperature Control: A high-precision temperature sensor, in combination with a PID (Proportional–Integral–Derivative) controller, regulates the internal temperature. Heating elements adjust the temperature based on the programmed test cycle.
• Humidity Regulation: The Relative Humidity (RH) inside the chamber is controlled using a humidifier and a dehumidifier system, working in tandem to maintain the setpoint RH (usually from 40% to 98%).
• Air Circulation: Uniform air circulation is maintained using internal fans to prevent hot or cold spots inside the chamber, ensuring consistent conditions throughout the test area.
• Monitoring and Data Logging: The system is integrated with digital sensors and microprocessors to continuously monitor environmental parameters. Real-time data is displayed on the control panel and stored for analysis.

This method ensures precise environmental replication for hours, days, or even weeks, allowing accurate simulation of real-life storage, transportation, and usage conditions.
