Humidity Chamber

Humidity test chamber typically consists of an insulated cabinet equipped with temperature and humidity control systems, as well as sensors to monitor and maintain the desired conditions. The test specimen is placed inside the chamber and exposed to the specified temperature and humidity conditions.
Humidity chambers are commonly used in industries such as electronics, pharmaceuticals, medical devices, and automotive manufacturing. They play a crucial role in ensuring that products are able to withstand the effects of harsh environmental conditions and meet the necessary quality and reliability standards.

What is the structure of the humidity test chamber for climatic testing

The structure of a humidity chamber depends on the manufacturer and model, but typically consists of the following main components:

1. Working Chamber: This part is used to create a controlled environment for testing. The chamber is typically made of stainless steel SUS#304 that are durable enough to withstand the extreme temperature and humidity conditions inside.

2. Insulation: To maintain temperature and humidity levels, the chamber is typically insulated with materials such as fiberglass or polyurethane.

3. Heating and cooling system: This system adopts forced air convection to perform heating and cooling tests. To realize temperature humidity control, the test chamber should be able to carry out two functions: heating and cooling, uniform temperature also must be evenly distributed inside the working chamber, Climatest Symor® makes it possible to achieve a high degree of temperature uniformity in the whole testing area.

Humidity chamber adopts mechanical cooling system and mechanical heating system to conduct testings on products:
Mechanical heating system consists of electric heating elements positioned near the ventilation system, so that the heated hot air is delivered into the testing zone from air inlet, then come out from air outlet, meanwhile, there are centrifugal fans located at the back of the air inlet, so as to blast the hot air to reach better uniformity.

Mechanical cooling system consists of a closed circuit system, with the following main components:

·Control valve

·Condensor

·Evaporator

·Compressor

The refrigeration system in a thermal test chamber is classified to be single stage and double stage, the single stage is adopted with temperature -40℃ and above, and double stage (also called cascade system) is with temperature below 40℃.

4.Humidity control system: The humidity control system is used to control the humidity inside the chamber. This system can include humidifying and dehumidifying systems.

5. Control panel: The control panel is used to operate the test chamber. It typically includes a display for temperature and humidity readings, as well as buttons or knobs for adjusting the temperature and humidity levels.

Programmable LCD touch screen controller:

·7 inch Japan programmable touch screen controller

·Set temperature point under fix value mode or programs mode

·Temperature set point and realtime temperature curve display ·100 groups program with 999 segment memory; each segment 99Hour59Min

·Test data can be downloaded as required through RS232 interface

6. Sample holders: Sample holders are used to securely hold the products or materials being tested inside the chamber. These can be shelves, trays, or other types of holders, depending on the size and type of the products being tested.

7. Door: The door of the test chamber is used to access the interior. The door should be sturdy, airtight, and able to withstand the temperature and humidity conditions inside the chamber.

These are the main components of a constant temperature and humidity test chamber. The exact design and structure of the chamber can vary depending on the manufacturer and model, but these components are typically present in most models.

How to place a sample in a humidity test chamber for climatic testing?
Placing a sample in a humidity chamber for climatic testing typically involves the following steps:
1.Preparation: Ensure that the sample is clean and free of any contaminants.
Loading the chamber: Open the door and place the sample inside. The sample must keep a certain distance from the inner wall of the test chamber to ensure air circulation around the sample. Once the air flow in the chamber is blocked, the uniformity of temperature and humidity in the test chamber is reduced, and the test error will increase.

In the case of air flow, the height of the sample shelf can be adjusted according to the size of the sample being tested.

3.Setting the conditions: Set the desired temperature and humidity value on the controller.
4.Monitoring the conditions: The conditions should be regularly checked to ensure that they are within the specified range.
5.Running the test: The test can begin. The sample should be left inside the chamber for the specified duration of the test.
6.Data collection: The chamber should be equipped with a data logging system to record the temperature and humidity conditions during the test. This data can be used to analyze the performance of the sample and the results of the test.
7.Removing the sample: After the test is complete, the sample should be removed from the chamber at ambient temperature, and carefully examined for any changes or damage that may have occurred during the test.
It's important to follow proper procedures and guidelines when using a humidity test chamber for climatic testing, to ensure that the results of the test are accurate.
