1. What is temperature humidity chamber?

The Temperature humidity chamber is also known as climate test chambers or environmental test chamber.  Temperature and Humidity Chamber can simulate the effects that a variety range of temperature and humidity conditions have on a tested product or material.

Temperature Humidity Chamber (also known as Temperature and Humidity Chamber) finds widespread usage in such products as telecommunication equipment or photovoltaic solar panels that are exposed to outdoor temperature and humidity environment.

Temperature Humidity Chamber also finds applications in such industries as food science, semiconductors, and military quality assurance.

A good temperature humidity chamber is critical for estimating potential success or failure of a product in the field.

Temperature humidity chamber has various sizes, ranging from a small box that is installed on the benchtop to a room-sized chamber for large objects or for checking large batches of products at the same time.


2. Why you need temperature humidity chamber?

Many products made from industry are easily vulnerable during storage, handling, manufacturing and practical installment and application due to such force majeure as humidity, bad weather, mindless and rude handling. These unpredictable factors will cause physical, or even functional damage in products, leading to great loss in your product’s effect, value and even threatening the life safety of customers who use it. Therefore you should take it seriously. At this time, the Temperature and Humidity Chamber is necessary!

Have you heard of explosion of an electronic appliance? Or met a predicament that a product that you purchase it just yesterday does not work? You know, all these problems were triggered by dearth of quality of your product.

It is necessary for you to conduct relative experiments to measure the quality and performance against the danger situation of your products before putting it into the market.

The temperature and humidity chambers is designed to simulate regular or specific environments in accordance with your requirements to test your product’s quality. You will find out the potential dangerous troubles hiding in your product with the help of the Temperature Humidity Chamber. With the help of the Temperature and Humidity Chamber, you could find them and solve them! You could perfect a product by collecting useful data from experiments and then grasp the heart of your customers and take a lion’s share in the market.

There are three reasons why you need Temperature Humidity Chamber:

  1. There are great differences between producing area and practical application area: Different fields have different weather conditions that vary in temperature and humidity. Your products may be superior in good resistance of dry, but less competitive in coping with unpredictable bad weather. Given that situation,I reckon that you need a temperature and humidity chamber to test your products many times in unpredictable bad conditions and then improve it.
  2. Your products will enjoy good fame and surpass your competitor with reliable quality: With a Temperature and Humidity Chamber, you could test the performance indicator of a product many times at specific conditions you want. And then, you could find the potential shortcoming of a product and then improve it. By doing this, you could constantly enhance the power of a product, making it both competitive in its appearance and practical application.


3. What Simulated Conditions the Temperature Humidity Chamber Provide?

Products from industry will be influenced by some environmental factors to some extent.

In order to test the ability of products to deal with the unpredictable natural disaster, temperature humidity chamber simulates the extreme condition that nature can’t absolutely attain. You could choose different kinds of Temperature Humidity Chamber for different experiments to achieve the ideal results.

With Temperature Humidity Chamber, you can know the limit of your products in the dangerous natural environment and the information about how long your products can be used in the perilous natural condition. The following are the three special conditions that the Temperature Humidity Chamber can take for you:

  1. Temperature variations:

With temperature varying, you could identify the thermal range that your products can bear.

  1. Humidity:

Being one of the most influential factors in environments, humidity is a force majeure for products during storage and transportation. Our product can control experiment humidity to test your product bearing.

  1. Simulate Weather:

Many products are mainly influenced by weather factors, such as rainfall. We provide you with Temperature and Humidity Chamber that could examine the tested product’s water-repellent performance by simulating a soaking, rainy environment. Temperature and Humidity Chamber can also simulate other weather environments, such as scorching sunlight.

How Does Temperature Humidity Test Chamber Work?     

  • Thermal shock test chamber (also known as Environment Stress Screen Test): It is developed to meet the demands of high accelerated stress (HAST) for electrical and electronic parts. By simulating two extreme two different conditions, it makes the tested products transfer between hot and cold zone to simulate fleet product temperature change rapidly. With the help of the experiment, your product’s performance against two totally different and extreme conditions is evident.

Thermal shock test chamber

  • Double-check high and low test chamber: It provides a constant high-temperature and low-temperature simulated environment ranging from -40℃to 150℃ (Available for tailored design). It is employed to examine the performance indicators of industrial products under extreme weather. It finds wider application in many fields, covering electronic and electric components, automobile and motorcycle, aerospace, shipbuilding, and other extreme temperature altering changes.

  • Walking in Test Chamber: It is applicable in large capacity test that requires high temperature and high humidity. The chamber is equipped with structural steel, the steady structure able to test the large parts and products. Our product is constructed with various optional functions for different test standards and requirements.


What is Temperature Humidity Chamber used for?

With the fast and rapid advancement of modern high-tech technology, electrical and electronic products have been widely employed. Meanwhile, the natural conditions are increasingly complicated and unpredictable. Only by reasonably regulating the protection measures of products, can the products be freed from unpredictable damage during storage and transportation, especially ocean carriage.

A  Humidity and Temperature Controlled Chamber can be also used when specific climate conditions (temperature and/or humidity) are needed for testing the performance of products when they are in a perilous natural condition, such as constant extreme cold and hot.

Moreover, our Temperature and Humidity Chamber (also called as Temperature Humidity Chamber) can also be designed for your specific needs. For example, before putting your product into the market, it is necessary for you to improve your products as many as possible, because only those products with good quality can stimulate customer’s buying appetite.
