Conditioning Chamber for Lab

A Conditioning Chamber for laboratory use (also commonly called a laboratory conditioning chamber, humidity conditioning chamber, constant temperature and humidity chamber, or environmental conditioning chamber) is a specialized enclosed device that maintains precise, controlled temperature and relative humidity (RH) levels inside the chamber. This creates standardized environmental conditions for preparing, storing, or “conditioning” samples/materials before physical, mechanical, or quality testing.

These chambers are essential in labs to ensure repeatable and accurate test results by eliminating variations caused by ambient room conditions (like fluctuating Delhi humidity or temperature).

Primary Purposes and Applications

• Textile and fabric testing — Most common use. Standards like ISO 139 require samples (yarn, fabric, garments) to be conditioned at 20–25°C and 65% RH (±2–4%) for 4–24 hours before tensile strength, colorfastness, dimensional stability, or other tests. Without proper conditioning, moisture content affects results dramatically.
• Materials testing — Plastics, rubber, paper, packaging, pharmaceuticals, and composites need stable conditions to avoid moisture absorption/desorption skewing properties.
• Other lab uses — Sample stabilization in civil engineering (e.g., asphalt/bitumen conditioning for IDEAL-CT or SCB tests), electronics, food, or biological samples before analysis.

Typical controlled ranges:

• Temperature: Often 0–94°C (most textile models focus on 18–30°C)
• Relative Humidity: 20–98% RH (±2–3% accuracy)

Key Features of Lab Conditioning Chambers

• PID controllers for precise, stable regulation
• Forced air circulation for uniform conditions
• Stainless steel interior, insulated walls
• Digital display and data logging (some models offer USB/export)
• Capacities: Benchtop (50–200 liters) to larger floor models (500+ liters)
• Safety features: Over-temperature protection, alarms

Advantages of humidity testing chamber

The ability of materials to withstand high temperatures and humidity may be readily tested in a variety of industries using a humidity testing chamber. This humidity testing chamber is essential for material stability testing, particularly in the pharmaceutical sector. The ability to quickly evaluate the dependability of electronic components and other relevant samples under high humidity levels is one of the main benefits that manufacturers will receive from using a humidity testing chamber. This will assist manufacturers in recognizing probable problems. These testing chambers aid in product development and environmental monitoring in addition to testing the materials’ resilience to humidity.
