Brief introduction to the list of common problems of programmable constant temperature and humidity machine
With the rapid development of science and technology, environmental testing equipment has been integrated into various fields such as colleges, well-known listed companies, military industry, aerospace, scientific research institutes, other large enterprises or foreign-funded enterprises, etc. The constant humidity test chamber has become an indispensable test instrument in the test equipment, so what are the common problems encountered when using a programmable constant temperature and humidity chamber? Sorting out and introducing the current environmental testing, users are using environmental testing equipment, and the problems and losses often encountered by the requirements of the specifications. If you have the following related questions, please contact the business department. We will serve you wholeheartedly.
What is the correct layout for environmental testing?
Description: The product to be tested is placed in the test area of ​​the machine. How to arrange it correctly? Is there any requirement in the specifications? Is it related to volume, weight, material? ?
When testing and integrating the constant temperature and humidity machine, how to arrange the test wire in the furnace?
Note: When performing test integration, how does the arrangement of the test wires in the furnace affect the validity and accuracy of the experiment?
What are the specifications for non-condensing machines for constant temperature and humidity machines?
Explanation: The specification is aimed at how the machine needs to be non-condensing. Can the machine be tested for condensation or non-condensation? How should the so-called machine non-condensation be determined? Affect, my things don't have electricity, so it doesn't matter if there is condensation?
Does dirty water affect the test?
Note: If the humidity of the constant temperature and humidity machine is used for water, if the water quality is not good for the test, what kind of water quality is qualified? Will it be affected if you use ordinary tap water?
Is there any difference between RO deionized water and distilled water for high temperature and high humidity test results?
Note: RO deionized water and distilled water are both very clean water, does that have any effect on the experiment?
What material should be used for the jig for placing the test object?
Note: In the constant temperature and humidity machine, what kind of material should be used for the jig used to place the test object, is it a bakelite board or a cardboard or a biscuit box and a wood board?
Do not set the temperature and humidity synchronous slope for high temperature and high humidity?
Note: When using a constant temperature and humidity machine for high-temperature and high-humidity tests, if the humidity synchronization slope is not set at the temperature rise and fall, will it affect the test?
Can I open the door halfway during the high temperature and high humidity test?
Note: Since there are many products to be tested by the company and the number of machines is not enough, it is necessary to open the door in the middle of the high-temperature and high-humidity test to place or take the test object. Does this affect the test results?
Will the test be effective after it is taken out and put in again?
Note: The test product is half taken out, and after a few days, it will be put back to test whether the test has continuity and whether it is effective. If it is just taken out, it does not matter at all, what will happen
Can I open the door halfway during the low temperature test?
Note: Since there are many products to be tested by the company and the number of machines is not enough, it is necessary to open the door at low temperature during the test to place or take the test product, which will affect the test results.
What is the effect of high temperature and humidity fluctuations on the test?
Note: What is the impact of the temperature and humidity fluctuations of the test furnace on the test product
Impact of machine noise on users?
Description: What kind of machine noise is suitable for it? Does it have any effect on the human body?
Does the heating load affect the test product and test?
Note: The heating load will be formed after the test product is energized. Is there any effect on the test furnace and the test product and the test results? What if the heating load exceeds the machine's tolerance?
How to calculate the heat load of the product under test?
Description: How to calculate the heat load generated by the product under test when it is powered, how to absorb and release heat from the material itself, and how to consider the load weight of the product itself
Why is there a test condition of 10% humidity?
Explanation: Why there are so-called humidity 10% test conditions among the environmental test conditions
Why is there a test condition of 5% humidity?
Explanation: Why there are so-called ultra-low humidity test conditions with a humidity of 5% among the environmental test conditions
Why do the temperature and humidity tests we see are all above 85% RH?
Explanation: Why are the humidity above 85% RH when conducting the so-called high-temperature and high-humidity test, why the humidity does not see the test conditions below 85R.H.
Why the test condition of so-called double 85 at 85 ℃ / 85% RH
Explanation: Why do you need to carry out the so-called double 85 test condition at 85 ° C / 85% RH, is it because of the heat resistance test, because everyone is doing it, because the customer requires it, is it right?
Why does the 85 ℃ / 85% RH test set the time to 168 hours?
Explanation: Why do you often see that the test time is 168 hours during the 85 ℃ / 85% RH test? What is the purpose?
How to calculate the estimated life of the product through the constant temperature and humidity machine?
Note: Can a constant temperature and humidity machine be used to calculate the estimated life of the product?
