Choosing the Right High And Low Temperature Chamber for Your Testing Needs

High and low temperature chambers are widely used in various industries such as electronics, electronics, aviation, chemical, military, etc. However, the testing requirements for products in different industries are not the same. So how to choose the appropriate high and low temperature chamber equipment for oneself?

Temperature range selection:
In order to meet the testing requirements of different products, there are currently multiple options for the temperature range of high and low temperature chamber equipment. The refrigeration system is the key to the equipment, while the heating system is relatively simple. Currently, the conventional options are -20 ℃~150 ℃, -40 ℃~150 ℃, -60 ℃~150 ℃. If customers have additional needs, they can also customize according to their needs. However, generally, the lower the low temperature, the more expensive the price is. Therefore, it is necessary to be clear about the temperature testing requirements of the product before purchasing equipment!

Studio size selection:
The size of the workroom in the high and low temperature chamber should be determined based on the customer’s test workpiece. In order to meet the accuracy requirements of the test, a certain amount of space should be reserved in the front and back, left and right, and up and down of the workroom during the test process, usually about 5CM. Therefore, it is generally required that the volume of the measured workpiece should not exceed two-thirds of the workroom volume to facilitate the circulation of the air duct and ensure the absolute temperature uniformity and fluctuation of the workroom, Achieve the goal of accurate testing!

Select based on site conditions:
Generally, high and low temperature chamber equipment has a high power and needs to have a voltage of 380V. Therefore, some factories and workshops require additional modifications to the circuit. Of course, users with low testing requirements can consider using a small test chamber with a voltage of 220V.

In addition, attention should be paid to the external dimensions of the test chamber equipment, as the test chamber is a large-scale equipment. It is necessary to consider whether the purchased equipment can pass through the laboratory doors, elevators, walkways, etc. to ensure smooth handling and use!

After sales service selection:
When choosing high and low temperature chamber, one should not only pay attention to the quality and details of the product, but also pay attention to the after-sales service that the manufacturer can provide. Because the testing equipment is a complex instrument, improper operation or long-term use can easily cause equipment problems, which requires the manufacturer’s assistance or after-sales maintenance. Therefore, the assessment of after-sales service ability is also one of the key indicators for selecting high and low temperature test chambers.

In the testing of high and low temperature test chambers, many people are aware of the problem, but they still do not know how to solve it. Here, we will provide you with several methods to solve the interruption problem.

1. When there is a problem with the equipment, the first step is to judge the interruption within the tolerance range based on the standard. Whether it is the interruption of the test conditions or the passing of the test conditions. After determining which situation the problem arises, targeted solutions can be provided.

2. If an interrupt occurs within the tolerance range, it means that the error is not significant and is still within a controllable range. At this point, analysis can be conducted based on the actual situation, and the time point of interruption can be used as a summary of the total testing time. In this way, the final test parameters have little error and are still usable.

3. If there is insufficient testing conditions in the high and low temperature test chamber, it is easy to waste energy. Therefore, when the test conditions exceed the allowable error range, it is necessary to meet the various condition values required for the test, that is, adjust the points of the test conditions to the predetermined test conditions in order to resume the test and continue with the original predetermined test cycle.

4. If there are any issues with the test conditions and if the test sample malfunctions during the testing process, it means that the final test results are also invalid. Therefore, if problems are found with the test samples, in order to prevent testing interruption, the test samples should be replaced first to ensure their correctness, and then the test should be restarted.

5. In addition, in the experiment, it is like a power outage. If there is an accident such as a water outage or equipment malfunction, the test will also be interrupted. It is necessary to seal the test chamber door and then check the test samples. If there are no issues with the sample, the equipment can quickly resume operation and can be handled according to the unqualified test conditions mentioned above.

In addition, it should be noted that when using a high and low temperature test chamber for testing, if the interruption time is less than 2 hours, the corresponding situation can be handled according to the regulations. If the time is longer than 2 hours, this test must be conducted again.

Several issues to pay attention to when operating high and low temperature test chambers:
During the operation of the high and low temperature chamber, it is necessary to remove debris from the equipment. The test chamber equipment should be operated according to the correct process to ensure the correctness of operation and avoid misoperation affecting the accuracy of the test. There are two overtemperature protectors in the internal distribution box of the equipment. Usually, do not adjust them randomly. The manufacturer has already adjusted the set values before leaving the factory.

The overtemperature protector is used to protect the heating and humidification pipes from burning out and water shortage alarms. In addition, at the end of the test, you must wear heat-resistant, electrically resistant, and dry gloves to remove the product. When taking out the test object from the chamber and during the process of opening and closing the door, do not let the rubber edge on the door come into contact with the object to avoid damaging the rubber edge and shortening its service life. We hope that everyone does not ignore these details in the use of high and low temperature chambers.

In addition, attention should also be paid to the cleaning and maintenance of the high and low temperature chambers. Regular maintenance and cleaning of the test chamber equipment is essential. The bottom and surrounding area of the high and low temperature chamber should be kept clean to prevent a large amount of dust from being sucked into the machine and affecting the testing performance of the equipment.

The cleaning of each component inside the chamber should be carried out according to the manufacturer’s formal process. The equipment should be cleaned at least once a year. The dust inside the electrical room can be removed with a vacuum cleaner, and the outside of the test chamber can be cleaned with soap and water. In addition, parts should be inspected regularly. If faults are found, they should be promptly inspected and repaired.
