Temp chamber,humidity chamber: What's the Difference?
In the field of enviromental chambers, you may encounter the terms enviromental chambers, climate control chamber, humidity chamber, thermal chamber, and temp chamber. After a while of exposure, you might start to wonder if there is a difference between them. These terms are basically used interchangeably, with no obvious difference. Although the term "environmental chambers" is more common, it is important to understand the specific test forms of each chamber when choosing the type of test that suits your needs.
Temp chamber and thermal chamber
If you are looking for a test chamber that provides the precise control required for temperature cycling, then a temp chamber (also known as a thermal chamber) is the ideal choice. These temperature chamber are commonly used to test a variety of products, including transportation and aircraft materials or medical devices.
The temperature chamber relies on an advanced heating system to ensure reliable test conditions and compliance with industry standards. The temperature range of the performance chamber is typically -70°C to 180°C (-94°F to 356°F). The airflow design of the chamber allows the fast reaction heater to strictly control the room temperature to achieve an accuracy of ±0.5°C. They range in volume from benchtop models of less than 1 cubic foot to walk-in or drive-in rooms.
Temp chambers are usually equipped with air cooling or water cooling systems. Air cooling systems are less costly, but the cooling rate is usually slower than water cooling systems. Water-cooling systems are more efficient, but require a more complex installation and a permanent water source. To further increase the cooling speed, you can choose to integrate liquid nitrogen (LN2) or carbon dioxide (CO2) into the system.
To ensure safety, the temp chamber is equipped with an adjustable high/low control function to prevent the temperature from going out of the set range during the test. In addition, the test chamber is equipped with an internal high temperature safety function and a refrigeration system with an overvoltage safety circuit. Together, these safety features constitute a reliable test environment that ensures the safety of the test and identifies the durability of the product.
Humidity chamber
In addition to temperature, many standards also require a humidity test. Humidity chambers are similar to temperature or heat chambers, ranging in size from benchtop to walk-in, and in performance.
A standard humidity chamber can simulate test conditions between 10% and 95% relative humidity (RH), which is the humidity that can be achieved at a given temperature. It is important to note that the RH at 5 degrees Celsius is very different from the RH at 32 degrees Celsius. For tests that require more extreme RH levels, up to 98% RH can be achieved using a high humidity sensor, or as low as 5% RH can be achieved using a desiccant air dryer.
The humidity chamber creates and tightly controls humidity conditions in the work space through a steam generator system. These steam systems usually consist of closed stainless steel or copper tubes. The water is heated into steam and mixed with conditioned air in the ventilated chamber through pipes and eventually into the work space.
The humidity chamber can perform steady-state or stability tests. While certain test standards require specific rates of rise and fall, if this is not necessary, it is recommended to choose a stability humidity chamber designed for long-term consistent testing.
The most common test chamber
JOEO has developed a suite of test rooms designed for a variety of industries, covering electric vehicles, aerospace, pharmaceuticals and more. Each test chamber is designed to meet a variety of needs and is designed to push the device under test (DUT) to its physical limits and simulate a wide range of real conditions it may face. Let's take a closer look at the types of environmental rooms we often see.Temp chamber and thermal chamber
