High and low temperature test chambers are widely used in many industries, so this equipment plays a pivotal role in the entire ring industry. Because the position of the equipment in this industry is so important, many manufacturers at home and abroad produce the equipment. As a professional environmental testing equipment, although its selectivity is many, the quality of the product is not good. So how to choose the right device, let me introduce it to you.
The high and low temperature test chambers are divided into two types: constant test chamber and alternating test chamber. The biggest difference between them is the difference in control methods. Ordinary high and low temperature test chambers are generally constant high and low temperature test chambers. The control method is: setting a target temperature, the device has the ability to automatically thermostat to the target temperature.
The high and low temperature change test box of the high and low temperature alternating test chamber and the program of the cycle are also required to be set, but the setting of the equipment program is not only one set, but also one set at a time. The test chamber can complete the experiment process according to the preset curve, and can accurately control the rate of the temperature rise and fall within the capability range of the maximum temperature rise and fall rate, that is, the temperature rise and fall rate can be controlled according to the slope of the set curve.
Although the high and low temperature alternating test chamber has the functions of constant test chamber preset temperature and humidity curve, the manufacturing cost of the alternating test chamber is relatively high, because the alternating test chamber needs to be equipped with a curve automatic recording device and a program control device, and needs to be solved. The test chamber opens the refrigerant and other problems when the temperature in the working chamber is high. Therefore, the price of the high and low temperature alternating test chamber is higher than that of the ordinary high and low temperature test chamber, so our users should seek truth from facts when choosing, and use the test box to select the appropriate test box.
