Effortless Sample Preparation & Placement for Humidity Testing In 3 Easy Steps

Humidity Chamber

Humidity is a significant environmental factor that can affect the stability and durability of various materials. This is why it's crucial to test materials against humidity levels to ensure their quality and performance in different environmental conditions. High humidity levels can cause the metals to get deteriorates over time.

Thus, to ensure that the materials will be tested against relative humidity, it is important for the manufacturers to conduct humidity tests on the materials. Thus, we at Presto have designed high-quality lab testing equipment known as a humidity chamberThis is one of the high-quality lab testing equipment that is used to test the humidity levels of the products at particular temperatures & humidity.

This will help the manufacturers in assessing different properties of the product under particular temperature and humidity levels. Presto is a leading humidity chamber manufacturer and designs this quality testing equipment as per industry standards.

In this blog, we are going to discuss a brief about humidity testing chamber, and how you can easily prepare the sample for conducting humidity test on the samples.

Presto humidity chamber: Best for testing humidity levels of products

Relative humidity testing allows manufacturers to assess how their products perform under specific humidity conditions. Many products, especially those sensitive to moisture, may experience changes in physical properties when exposed to varying levels of humidity.

Thus, to test the physical properties of the materials at relative humidity, we at Presto have designed high-quality lab testing equipment known as a humidity testing chamber.

This testing equipment has been designed with sophisticated technology that makes it easy for manufacturers to conduct humidity tests on the materials.

This chamber will also maintain the testing samples at particular temperature and humidity levels to assess the change. It comes with digital control for humidity and temperature and provides maximum thermal efficiency by insulation means.

This quality testing instrument has been equipped with a rapid air circulation German imported fan for uniform and homogenous heating, cooling and de-humidity.

Below we have listed the features and technical specifications of this quality lab testing equipment.

This highly efficient humidity testing chamber will accurately measure the quality of products and ensure accuracy in testing results.          

Now, let us discuss the steps to prepare a sample for the humidity test.

3 easy steps to prepare & place the sample for humidity test

Preparing and placing a sample for humidity testing can be done in three simple steps:

Step 1: Unlock the door

Start by unlocking both the stainless steel (S.S.) door and the glass door of the humidity chamber. This will allow access to the testing chamber and the sample placement plate.

Step 2: Place the sample

Take the sample that needs to be tested and carefully position it on the S.S. sample placement plate inside the humidity chamber. Ensure that the sample is properly centred and placed securely on the plate.

Step 3: Close the doors

After placing the sample, close both the S.S. door and the glass door of the humidity chamber. Make sure to close them appropriately and securely to maintain a sealed environment inside the chamber. This is important for accurate humidity testing and to prevent any external moisture from affecting the sample.

By following these three easy steps properly, the sample will be ready for humidity testing in the controlled environment of the chamber.
