Temperature-Humidity Chambers

Temperature-humidity chambers refer to specially designed pieces of equipment used in stability testing to test how well a product or material retains its quality over its lifetime. This equipment provides a trusted and reliable way to conduct stability testing on biological items, industrial products, materials and pharmaceutical products.

These chambers can be used to simulate the exposure of a number of different environmental conditions on products and materials. Some of these environmental conditions include:

• Extreme temperatures

• Sudden and extreme temperature variations

• Moisture or relative humidity

• Electro-dynamic vibrations

• Electromagnetic radiation

• Salt spray

• Rain

• Weathering

• Exposure to sun (causing UV degradation)

When selecting a temperature-humidity chamber, it is essential to thoroughly research what is available in the market based and select the best one based on the needs of each individual project.

Testing Humidity with Chambers:

Temperature-humidity chambers are able to simulate a variety of different weather conditions. In the following section of the article, we will explore how they can be used to test what effect humidity would have on a particular product.

Step 1:

Pierce a humidity capsule and place it in the chamber to create the required levels of humidity. Humidity capsules can be used to produce levels of relative humidity in the range of 0-95%, increasing at 5% increments. The particular humidity capsule should be chosen based on the aims of each particular test.

Step 2:

Place the test sample in a separate section of the chamber.

Step 3:

Place a sensor cap to on top of the unit to tightly seal the temperature-humidity chamber. This will allow you to measure the level of humidity within the unit for the duration of the test.

Step 4:

Affix a logger cap onto the base of the chamber. The logger cap can be connected to any laptop or computer via a USB cable or a wireless connection. If your test is being performed outside of wireless range, you can use aerials and cabling to broadcast the signal of your unit.

Step 5:

Incubate tests at the required temperature. When the tests are complete dispose of the temperature-humidity chamber. Using a temperature-humidity chamber to conduct stability testing can result in a number of practical benefits such as:

• Act as suitable environmental chambers

• Each test is monitored in its own micro-humidity chamber

• You can select from a full range of temperature, weather and humidity conditions

• Allow you to continuously collect data throughout the study for each test

• Chambers assist with lowering cross contamination and improving sample integrity

• The sensors of each chamber can be easily calibrated

• Eliminate the need for alt solutions or desiccators

• Units are easy to set-up

• Units are ideal for working with toxic materials

• The system can be used for monitoring and mapping applications

• Data can be automatically backed up throughout the project.
