What Exactly Is an Environmental Test Chamber, and How Does It Work?

Sep 21

Electrical and electronic products have become increasingly popular as modern industrial technology has advanced. At the same time, environmental conditions are becoming increasingly complex. Only by properly regulating the environmental protection measures of the products can they be protected from damage during storage and transportation, as well as safe and reliable when in use. As a result, the use of electrical and electronic products in artificially simulated environmental tests is critical to ensuring high quality.

In this article, we will define a test chamber and explain how an environmental chamber works.

What Exactly is an Environmental Test Chamber?

Before we begin learning about environmental test chambers, we should first understand what an environmental test is and where it can be used. This test is not difficult; the principle behind it is widely used in our daily lives, such as refrigerators, which can change temperature to keep food from spoiling.

Every industrial product will suffer from environmental damage. The Environmental Test can assist you in determining the point at which the product will be damaged. The Environmental Test Chambers accelerate the changing of the environment or add extreme conditions that the natural cannot reach in order to measure the availability of your products.

As a result, with the help of the Environmental Test Chamber, you can learn how long your products can be used in nature, as well as the maximum temperature that your products can reach in an extreme environment.

Some of the conditions that the Environmental Test Chamber can handle for you are as follows:

1.Temperature variations: Temperature variations allow you to determine the thermal section that your products can withstand.

2.Humidity: As one of the most powerful environmental factors, humidity constantly bothers products. We can easily change the humidity for your products bearing using the Environmental Test Chamber.

3.Salt spray: Also known as a salt fog test, the salt spray test is one of the most widely used corrosion testing methods.

4.UV degradation: Because many products are constantly exposed to sunlight, it is necessary for your products to undergo a UV degradation test, which can assist you in determining the bearing section of that.

5.Vacuum: This is the vacuum condition for some specialized products.

6.Stimulate weather: For some products that are heavily influenced by weather conditions.


Most Environmental Test Chambers can change the conditions we've listed, and we can classify the Chambers based on that.

Among the representative test chambers are:

  • Chamber for thermal shock testing
  • Test chamber for salt spray
  • Test chamber for ultraviolet aging
  • Test chamber for aging Xenon lamps
  • Test chamber for ozone aging
  • Temperature chambers for high and low temperatures
  • Test chamber with constant temperature and humidity
  • Temperature, humidity, and vibration are all tested in the same chamber

We use different test chambers for different purposes; for environmental tests, the chamber is typically used for four main tests.


Steady State Tests: The chamber controls the temperature, humidity, and other factors in a specific range and holds the temperature for a set period of time. This type of test can be used to determine the service life of your products or to test their stability in a given environment over a long period of time. This test will produce more accurate results.

Thermal Cycling Tests: During this test, the chamber creates two extreme environments for your products and alternates between them over time. It is a time-consuming process. The variation of your products should be visible during this test.

Thermal Shock Tests: As the name implies, the chamber creates an extreme environment for your products in a short period of time. Then you'll find their peak bearing in relation to the extreme environment.

Slat Spray Test: Also known as the salt fog test, this is a popular corrosion test. Using this test, you can determine the availability of your products when they are exposed to real-world conditions.

The thermal cycling tests are similar to the thermal shock tests, but they are not the same. Thermal cycling testing takes longer than thermal shock testing. Though both provide two environments for products, thermal cycling is a slower test than thermal shock. Thermal cycling tests would produce accurate results for manufacturers if temperature and humidity were controlled. The thermal shock test, on the other hand, will collect data on the durability of your products in a switching two extreme environments.

The size of an environmental test chamber can range from a walk-in or drive-in chamber to a small chamber that can be placed on a large desk or somewhere similar.

What Is The Function of an Environmental Chamber?

The temperature and humidity test chamber can be used to evaluate electronic, electrical appliances, food, automobiles, rubber, plastic glue, metal, and other products. It can withstand a variety of environmental conditions, including high temperatures and high humidity, high temperatures and low humidity, low temperatures and high humidity, and high temperatures and low temperatures, and it will provide you with a foundation for forecasting and improving product quality and reliability.

Temperature and refrigeration systems are primarily used. The primary function is cooling, which is accomplished by employing advanced refrigerator control technology to stabilize the test space. Second, the test chamber must employ a dehumidification system to address the issue of humidity.

High low temperature test chambers are ideal for high and low temperature reliability testing of industrial products. Test the performance indicators of parts and materials used in related products such as electric and electronic, automobile and motorcycle, aerospace, shipbuilding, colleges and universities, research institutes, and other high-temperature and low-temperature (alternating) cyclical changes.

Constant temperature humidity test chambers are also known as constant temperature humidity test machines. It is used to assess the heat resistance, cold resistance, dry resistance, and moisture resistance of various materials. It can be used in electronics, electrical appliances, communication, instruments, vehicles, plastics, metals, food, chemicals, and building materials.

The salt spray corrosion test chamber can assess the material's and its protective layer's salt spray corrosion resistance, as well as the process quality of similar protective layers. Simultaneously, it can assess the resistance of some products to salt spray corrosion. The product is appropriate for both parts and electronics. Protective coatings for metallic materials and salt spray corrosion tests for industrial products are unique.

The thermal shock test chamber typically employs two extreme environments, into which the product is placed and the two environments are rapidly switched. This test demonstrates a product's resistance to switching between extreme environments.

What Is The Purpose of Environmental Test Chambers?

During manufacturing, handling, storage, and application, industrial products are subjected to a variety of temperature, humidity, climate, and environmental conditions. These elements may cause physical, mechanical, or even chemical changes in the product. This will cause the product to lose its effectiveness, reduce its value, or create a hazard!

Have you ever heard a cell phone explode? Or have you ever encountered a situation in which a product fails to function even when used for the first time? All of these issues were caused by a lack of quality in your products. As a result, it is critical that you conduct a test to determine the durability of your products!

Environmental Test Chambers simulate real-world or external environments in order to assess the durability of your products. With ECT Chambers, you can change the temperature or humidity, even create your own climate, and find problems that are hidden beneath the gleaming surface of your product.

Locate them! And then solve them! Your products will become even better!

In the case of Environmental Test Chambers, however, the data obtained from the test is valuable for your research and development.

Environmental Test Chambers Are Required For a Variety of Reasons, Including:

  1. There are climate differences between your target markets and your production area: Different areas have different climates caused by variations in temperature and humidity. Your products may be dry-weather resistant, but they are difficult to exist in wet weather. Keeping this in mind, you'll need an Environmental Test Chamber for your products.
  2. Your products are more dependable than your competitors if they are of high quality: With Environmental Test Chambers, you can measure your products multiple times, identify and solve problems, and improve the quality of your products.
  3. Customers prefer durable, crushing-resistant products; the former can increase the value of the product, but the latter comes from a safety standpoint.

During manufacturing, handling, storage, and application, industrial products are subjected to a variety of temperature, humidity, climate, and environmental conditions. These elements may cause physical, mechanical, or even chemical changes in the product. This will cause the product to lose its effectiveness, reduce its value, or create a hazard!

As we all know, a car that has not been weather tested cannot be sold. The weather test can assist manufacturers in determining which parts of cars are poorly assembled. Finally, with many times of weather testing, promote the car's safety. The product can only be sold if it passes this test.
