Constant temperature and humidity testing machine temperature cycle changes in the current society applies to electronic and electrical components, automation components, communications components, auto parts, metal, plastic and other industries, defense industry, aerospace, military industry, electronic chip IC, semiconductor ceramics and high The physical changes and chemical reactions that take place between molecular materials. The temperature cycle change of the constant temperature and humidity tester as an ambient temperature test uses a better standard value of the test among the values ​​of the temperature range value. Special tests were performed to test the samples for the most heat, cold, moisture, and dry resistance. It is composed of two parts: temperature regulation and temperature increase. The adjustment between the temperatures is the temperature required for the test chamber to reach the test state. In a constant temperature and humidity testing machine, there are changes between its four temperatures. Situation, how to control how to change it? 1. During the cooling process, this process is a much more complex process of relatively warming, and is mainly cooled by the compressor, so that when the temperature is maintained for a period of time, the temperature will be reduced to a certain standard. At the same time, the rate of cooling should be within the specified time; 2. For a constant low-temperature condition, when the temperature drops to a low temperature for a constant period of time, it should be noted that the entire process should be completed within 24 hours before it can end. 3. In the process of temperature increase in the constant temperature and humidity testing machine, as a relatively simple process in the entire temperature change, the temperature is increased by its electric heating method, and the temperature of the constant temperature and humidity testing machine is increased to the most standard. In the standard value, and for the simultaneous warming speed is also within its allowable range, which can not be raised too fast or too slow; 4. In its constant high temperature state, when its temperature reaches the set temperature, it should ensure that the temperature of its test chamber is maintained within this range until it reaches the set constant temperature time;   The temperature cycle change of the constant temperature and humidity testing machine is that the test product must be resistant to high temperature and low temperature, so the high and low temperature test provided by the constant temperature and humidity testing machine becomes an indispensable test instrument, and the temperature cycle change of the constant temperature and humidity tester can be more accurate. The detection of product performance changes in the case of temperature changes to achieve test purposes Dot peen marking works by electromechanically striking a carbide or diamond stylus assembly against the surface of a part to be marked.For example,dog tag engraver.The result is a succession of dots to create digits, text, logos, and 2D data matrix codes. Each such dot is the result of a pulsed current that runs through a solenoid, punches a magnet toward the surface, and subsequently returns the stylus to its starting position, awaiting the next pulse. Because each pulse occurs in only a fraction of a second, an entire 2D data matrix code, for example, can be completed in seconds (depending on the size).
Compressed air is not required.
