OEM Temp Humidity Chamber Three Element Compound Cold Cycle Ring
put to use:
Reasonable selection of high and low temperature test chamber test equipment. In order to ensure the normal conduct of the test, should be according to the different conditions of the test sample, the selection of appropriate test equipment, test sample and the effective volume of the test chamber should also maintain a reasonable ratio. For the test of the heating test sample, the volume shall not be greater than one tenth of the effective volume of the test chamber. For non - heating test samples, the volume should not be greater than one fifth of the effective volume of the test chamber. For example, a 21 'color TV in the temperature storage test, choose a cubic volume of the test box can meet the requirements, and in the power work, it can not meet the requirements, should change a larger test box, because the TV at work to diverge heat. In the high and low temperature test chamber environment test, the required test sample performance, test conditions/test procedures and test technology to be familiar with, to be familiar with the technical performance of the test equipment used to be familiar with, to understand the structure of the equipment, especially the operation and performance of the controller to be familiar with. Also carefully read the operation manual of the test equipment, so as to avoid the abnormal operation of the test equipment caused by the error of operation, which can cause the damage of the test sample and the incorrect test data
The main difference:
The difference between high and low temperature test chamber and high and low temperature alternating test chamber mainly lies in the control part and the refrigeration part. Control part of the high and low temperature test chamber is mainly controlled by digital display instrument, high and low temperature alternating test chamber is controlled by programmable controller, digital display instrument for manual control commonly, can follow the orders for the single, while the programmable controller is automatic control, can advance to set the number of parameters and test set in, Then follow the set program. The refrigeration part of the high and low temperature test chamber is relatively simple, as long as it can be constant at a certain temperature. And the high and low temperature alternating test chamber needs to measure a certain amount of cold, in order to output different amounts of cold at different temperature points, to achieve alternating. Their box structure is basically the same, the technical parameters are the same.
