The test chamber is a commonly used instrument in the industrial production process. Mainly used for a variety of materials, products, and components of the test and detection. High and low-temperature test chambers and constant-temperature humidity test chambers are commonly used test chambers. So, what makes these two test chambers different? And how will we buy it?
Brief definition of these two types of chambers
High-low Temperature Chamber
High-low temperature chambers can simulate the durability of objects in harsh environments. It can perform many different tests. For example, high temperature, low temperature, temperature change cycle, and other tests.
Constant Temperature and Humidity Test Chamber
The temperature and humidity of the constant temperature and humidity test chamber are constant. It can simulate and detect the durability of objects under any conditions.
The Difference Between Temperature and Humidity Control
High-low-temperature chambers and constant-temperature humidity chambers have different control methods. The main difference is the way of temperature and humidity control.
High-low Temperature Chamber
High-low temperature chamber through the setting of temperature and humidity control parameters. Then, through the electric heating and refrigeration system. Realize the rapid increase and decrease of the ambient temperature. Thus simulating the durability of articles in high and low-temperature environments.
Constant Temperature and Humidity Test Chamber
Precise temperature and humidity control systems for constant temperature and humidity test chambers. This makes the temperature humidity of the constant temperature humidity chamber more stable. It is suitable for testing products that need high ambient temperature and humidity.
Differences in Equipment structure
High-low-temperature chamber and constant temperature humidity test chamber structures are different. The high-low temperature chamber is divided into auxiliary equipment and control systems. The control system consists of two parts: electrical control and temperature control.
Constant temperature humidity chamber by the refrigeration system, heating system, humidity control system, ventilation system, and other components. It can realize more complex and diverse test requirements.
Test chamber composition
The composition of a high-low-temperature chamber includes refrigeration, heating, control, air circulation, and sensors. Functions include high temperature, low temperature, and temperature cycling tests. In contrast, constant temperature and humidity test chambers have an extra humidity system. It can perform high-temperature, low-temperature, and humidity cycle tests.
Both literally and working principle, these two test chambers’ difference is “wet”. That is, high and low-temperature test chambers can only do temperature tests. A constant temperature humidity chamber cannot only do a temperature test but also a humidity test.
The former is about $400 cheaper than the latter because the former has fewer features than the latter. When the user chooses, try to choose the latter if the budget allows. Even if only a temperature test is needed at the moment. If a humidity test is required for the product at a later stage. Purchasing extra equipment will cost more.
Selection from the application industry
Temperature chambers are aviation, home appliances, automotive of essential equipment. It determines the performance of the product as it changes with the temperature environment. It is mainly used for high, low, or constant temperature testing.
A constant temperature humidity chamber is suitable for product temperature and humidity change tests. Constant temperature humidity equipment has a large range of temperature and humidity manipulation. It can do a variety of different tests. For example, high temperature and high humidity test, constant hot humid test chamber. Used to test materials for resistance to low temperature, high temperature, dry, and water. At this stage, it applies to a variety of industry fields. For example, textile trade, food, lighting fixtures, chemical plants, and so on.
Selection from functional needs
High and low temperature chambers only function to regulate temperature. It is capable of performing tests in various high and low-temperature environments. It can also be called a high and low-temperature alternating test chamber. But can not carry out humidity inspection tests!
Constant temperature and humidity equipment can test both high and low-temperature environments. At the same time, a humidity test can also be added. It can control the temperature and humidity conditions at the same time. Requirements for temperature and humidity under the set rate of simultaneous changes. Create a simulation of realistic environmental conditions. Can meet the quality inspection needs. Constant temperature and humidity boxes can do both high and low temperatures. It also dehumidifies and circulates. It can also be called a “high and low-temperature humidity and heat tester”. Constant temperature and humidity chambers are generally capable of performing “hot and humid tests”.The supplier designs and adjusts the equipment according to the different test conditions.
High and low-temperature heat and humidity test chamber:
The general temperature will be -20 degrees or lower and can do humidity (only limited to 15 ~ 85 degrees). A damp heat alternating test means that the temperature remains constant over a period of time. Humidity according to your set rate of change for the test. Some tests need the temperature and humidity to change at the same time at a set rate. General constant temperature and humidity test after the temperature reaches. Only in this way can humidity be controlled. Alternating refers to the simultaneous control of temperature and humidity.
Constant temperature and humidity chamber:
Generally refers to the temperature of 15 degrees ~ 85 degrees, can do humidity 20% ~ 98% r.h. Of course, according to the requirements of the lower humidity. We call low temperature and low humidity test boxes.
Summarize
High low-temperature chambers and constant temperature humidity chamber’s use functions are different. During the purchasing process, it is best to pick according to your practical requirements. The pharmaceutical, food, and wine industries have high requirements for temperature and humidity. It is better to choose a constant temperature and humidity test chamber at this time.
If customers want to test the product performance and parameters in humid air. It is best to choose constant temperature and humidity test equipment. If testing the performance of a product in a low or high-temperature environment. Simply select the high and low-temperature test equipment.
Constant temperature humidity chambers and high-low temperature chambers test how well products can handle different conditions. The constant temperature humidity tester and the high low-temperature tester look similar. However, they work differently. Understanding the differences can help users choose the right equipment for their product testing needs.
