High and low temperature test boxes are widely used in many industries, and the equipment plays an important role in the entire industry. Because the equipment is so important in this industry, there are many manufacturers at home and abroad producing this equipment, and as a professional environmental testing equipment, although its selectivity is high, the quality of the products is mixed.
The high and low temperature test chambers are divided into two situations: a constant test chamber and an alternating test chamber. The difference between them is the control method. An ordinary high and low temperature laboratory is generally a constant high and low temperature laboratory. The control method is to set the target temperature, and the device has the ability to automatically keep the target temperature constant.
The high and low temperature changes of the high and low temperature alternating laboratory and the cycle plan also need to be set, but the equipment program settings can be set not only one at a time, but also multiple settings at a time. The laboratory can complete the experiment according to the set curve during the process, the rising and cooling rate can be controlled according to the slope of the set curve, that is, the temperature rise and cooling rate can be controlled according to the slope of the set curve.
Although the high and low temperature alternating test room has the function of setting the temperature and humidity curve in the constant test box, the manufacturing cost of the alternating current test box is relatively high, because the alternating temperature test room needs to be equipped with an automatic curve recording device and a program controller. It is also necessary to solve the problem of refrigerant opening in the high temperature test chamber.
Therefore, the price of the high and low temperature alternating test box is higher than that of the ordinary high and low temperature test box. Users should seek truth from facts when choosing, and choose the appropriate test box according to the needs of the test method.
