Exploring MTS Environmental Chambers: Principles, Applications, and Simulated Environments

October 12,2023


MTS environmental chambers play a vital role in various industries, enabling the precise testing of products and materials under controlled environmental conditions. In this blog, we will delve into the working principles of MTS environmental chambers, the types of products and materials they are used to test, and the range of environmental conditions they can simulate.

Working Principles of MTS Environmental Chambers

MTS environmental chambers are designed to replicate and control specific environmental conditions, including temperature, humidity, pressure, and sometimes even vibration. The chambers consist of a robust, thermally insulated structure with various sensors, controllers, and actuators. The fundamental working principles can be broken down into the following key components:

1. Temperature Control: MTS chambers utilise heating and cooling systems to regulate temperature. Electric heaters or refrigeration systems are employed to heat or cool the chamber, and temperature sensors provide feedback to maintain the desired setpoint.

2. Humidity Control: Some chambers are equipped with humidity control systems, allowing them to simulate different levels of relative humidity. Humidifiers and dehumidifiers are used in conjunction with humidity sensors to achieve precise humidity levels.

3. Pressure Control: In applications where pressure is a critical factor, MTS chambers can maintain specific pressure conditions. Pressure regulators and sensors are employed to control the chamber's internal pressure.

4. Environmental Monitoring: Sensors continuously monitor the environmental conditions inside the chamber, providing data that is crucial for maintaining the set conditions.

5. User Control: MTS chambers are typically user-friendly, with software interfaces that allow operators to set and adjust parameters such as temperature, humidity, and pressure. Automated sequences can also be programmed for more complex testing.

Applications of MTS Environmental Chambers

MTS environmental chambers are versatile tools used in a wide range of industries and research fields. They find applications in:

1. Electronics Testing: Environmental chambers are commonly used to test electronic components and devices. These tests can involve subjecting the products to extreme temperatures, humidity, and pressure to evaluate their performance under various conditions.

2. Material Testing: These chambers are instrumental in material science for assessing the behaviour of materials under different environmental stressors. For example, they can be used to study the effects of temperature variations on polymers or the corrosion of metals in humid conditions.

3. Pharmaceutical and Biomedical Research: Environmental chambers are vital for testing the stability and performance of pharmaceuticals, vaccines, and medical devices. Maintaining specific temperature and humidity conditions is essential to ensuring product integrity.

4. Automotive and Aerospace Industries: In these industries, environmental chambers are used to simulate the conditions that vehicles and aircraft might encounter during their operational lives. This includes extreme temperature variations, humidity, and pressure changes.

5. Food and Beverage Testing: Environmental chambers are employed to evaluate the shelf life of food products under different storage conditions, including temperature and humidity.

Simulated Environmental Conditions

MTS environmental chambers can accurately replicate a wide range of environmental conditions, including:

1. Temperature Variations: Chambers can simulate both high and low temperatures, ranging from extreme cold to intense heat. This is crucial for testing products that will be exposed to temperature fluctuations in real-world applications.

2. Humidity Levels: Chambers can replicate conditions of high humidity or bone-dry environments, allowing for testing materials and products that are sensitive to moisture.

3. Altitude and Pressure: Some chambers can simulate high-altitude conditions or low-pressure environments, which are important for aerospace and high-altitude testing.

4. Vibration and Mechanical Stress: In addition to the standard environmental conditions, some chambers may be equipped with vibration systems to test how products respond to mechanical stress under specific environmental conditions.


MTS environmental chambers are indispensable tools for industries and researchers seeking to understand how products and materials perform under various environmental conditions. Their ability to precisely control temperature, humidity, and pressure enables comprehensive testing and ensures product reliability. By simulating a wide range of environmental conditions, these chambers contribute to product development and quality assurance.
