The fundamental difference between high and low temperature test chamber and constant temperature and humidity chamber

There are many types of equipment in the environmental test equipment industry. The high and low temperature test chamber and the constant temperature and humidity test chamber are two different types of equipment for environmental testing. From the appearance, they are not big but they are different. The tests they make are very different. What is the difference between the constant temperature and humidity test chamber and the high and low temperature alternating chamber? Now let's briefly explain the difference between the two devices.

First of all, we must understand what your "high and low temperature alternating box" means? The fundamental difference between the high and low temperature test box and the constant temperature and humidity box

1. Only do high temperature and low temperature without humidity, directly called high and low temperature test chamber. It can also be called "high and low temperature alternating test chamber";

2. To do high temperature and low temperature, at the same time to be able to do humidity, for circulation, we call high and low temperature humid heat alternating test box, constant temperature and humidity box, etc .;

Generally, the constant temperature and humidity chamber can do "damp heat alternating test" but it depends on the alternating test conditions you have done. If you want to buy equipment, you should inform the supplier of your requirements before you buy the equipment. So that the equipment can be designed and debugged according to your requirements. Of course, according to the conditions you mentioned, the manufacturer's price is different.

Constant temperature and humidity box: generally refers to the temperature of 15 degrees to 85 degrees, can do humidity 20% to 98% RH, of course, can also do lower humidity according to requirements, we call the low temperature and low humidity test box.

High and low temperature humidity and heat alternating test chamber: the general temperature will be -20 degrees or lower, and can be used for humidity (only limited to 15 to 85 degrees). The damp-heat alternating test is mainly: during a certain period of time, the temperature remains unchanged and the humidity is tested at the rate of change you set, or vice versa. Some tests require that temperature and humidity change simultaneously at a set rate. The general constant temperature and humidity test is to control the humidity after the temperature reaches first (in a word: alternating means to control the temperature and humidity at the same time).
