Constant temperature and humidity and high temperature testing machine, what is the difference? What's the difference between them? We start from their definitions have anything in common, so that it can be more clear understanding of constant temperature and humidity and high and low temperature test machine.
Constant temperature and humidity can be called high and low temperature test machine, constant temperature testing machine or test box with constant temperature and humidity, the design criteria: GB/T2423//5170/10586, JIS C60068, ASTM D4714, CNS3625/12565/12566
Table type constant temperature and humidity test machine uses: This product can be simulated high temperature and high humidity, high temperature and low humidity, low temperature and low humidity and different test environment. It is suitable for simulating the aging resistance of various materials in a variety of specific environments, and can also be used as a sample pretreatment for other physical testing.
High and low temperature in the strict sense and with constant temperature and humidity test chamber is a little different, high and low temperature literal above to understand is that the high and low temperature; constant temperature and humidity test chamber is low and high temperature, and relative humidity (range: 20%-98%), can better simulated atmospheric environment. Constant temperature and humidity test box function contains the function of high and low temperature test box.
If you only need to do temperature, without the need for humidity, you can select the high and low temperature; single if your product test above a humidity control requirement is needed for test box with constant temperature and humidity of, this is the main points, you choose to buy must be special attention.
Some customers may ask, why not buy a test box with constant temperature and humidity can be?
Of course, this is also considered a cost issue. If you do not have to do humidity, humidity is required for spare parts can be saved, the relative cost of about 2000, if your budget is limited, must be controlled in a range, the test does not need to do humidity, you can choose not to moderate, buy high and low temperature box. This is a little suggestion!
If considering the practicality, taking into account the late development of products may use humidity control, it is recommended that you it is best to buy test box with constant temperature and humidity, multi use of the machine and also eliminates after may want to buy a machine trouble.
