Comparison of High and Low Temperature Test Chambers and Constant Temperature and Humidity Test Chambers
Today, Dongguan Kevin Test Equipment Co., Ltd. professional sales staff for the majority of customers and friends to explain in detail the similarities and differences of several devices, to facilitate the comparison of customers and friends at the time of purchase and the general use of each device; usually we introduce environmental products with customers At that time, many customers would often ask when comparing high and low temperature test chambers with the prices of other equipment, such as cold and hot shock test chambers, constant temperature and humidity test chambers, all of which are made of high temperature and low temperature, why the thermal shock test chambers The price is very expensive, is the high and low temperature test chamber and temperature and humidity chamber several times? The hot and cold impact test chamber is a large-scale, high-precision and complex test chamber that can form high-temperature, low-temperature, high-low-temperature difference inside the test chamber. The high-low temperature test chamber is a common type that can form high temperature, low temperature, and high temperature difference in the test chamber. Structure Test Chamber A constant temperature and humidity test chamber that can form high temperature and humidity precision chambers in the test chamber. Because the configuration of cold and heat shock test chambers and high and low temperature test chambers and constant temperature and humidity test chambers are not the same, the price of cold and heat shock test chambers will generally be several times more expensive than high and low temperature test chambers and constant temperature and humidity test chambers, and even more. High, thanks to the user's friends for spending a minute to browse this article, to have a certain understanding of the subsequent purchase of equipment, or you may need to plan to purchase this equipment, you can also call our company, our professional professionals for you to know in detail, Thank you!

1. The similarities and differences of the volume of the inner box The volume of the inner box of the high and low temperature test box and the constant temperature and humidity test box generally accounts for 1/3 of the whole, while the inner box of the cold and heat shock test box has the size of 1/8 of the outer box size. Two temperature storage boxes are hidden inside the hot and cold impact tester. One hot and cold impact tester is equivalent to three high and low temperature test boxes and a constant temperature and humidity test box. The high temperature area of ​​the hot and cold impact tester is only responsible for storing high temperature energy. The low temperature area of ​​the hot and cold impact tester is only responsible for storing low temperature energy. The experimental area of ​​the hot and cold impact tester is responsible for receiving high or low temperature energy exchange, high and low temperature test chambers and constant temperature and humidity tests. There is only one zone in the tank. The experimental zone can be controlled to be a high temperature or low temperature zone by program control.
2, the similarities and differences of the test function Because the thermal shock is independent of the three zones, so the exchange speed of high and low temperature energy is very fast, you can complete the high temperature to low temperature exchange in 2 minutes, because the thermal shock test machine exchange mode energy Fast neutralization, or mandatory neutralization. High and low temperature test chambers and constant temperature and humidity test chambers are one area, so the exchange of high and low temperature energy is a slow process. It is to take away the heat little by little by the refrigerant or by heating the system to neutralize the cold.
3. The similarities and differences in the structure of the airframe are mainly different from the cooling system. The cooling of the cold and hot shock chambers is a two-group cascade refrigeration system. Therefore, there are two refrigeration heads and other auxiliary components used in conjunction with the high and low temperature chambers for single-stage refrigeration. With only one nose, there are many auxiliary accessories.
