What Tests Make the Door of a Constant Temperature and Humidity Test Chamber Heat Up?

The constant temperature and humidity test chamber has its unique value in various fields, and the market space of the equipment expands with the growth of its technology. This equipment is also known as a wet-heat alternating test box. Its main testing durability includes heat resistance, cold resistance, dry resistance, and wet resistance of various materials. It is suitable for use in factories for electronics, electrical appliances, food, vehicles, metals, chemicals, and building materials.

But why does the door of the constant temperature and humidity test chamber heat up during low-temperature testing? Customers often encounter such problems and consult our technicians. This is a common phenomenon. Let us explain it briefly below.

1. Development of Constant Temperature and Humidity Test Chamber

The development of the constant temperature and humidity test chamber relies not only on high technology but also on its unique design and high-end materials. The equipment is mainly made of 304 stainless steel stamping, with a beautiful sheet metal structure, compressor, and high-quality controller, which is the loyal choice for many manufacturers.

2. Design of the Constant Temperature and Humidity Test Chamber

The unique design of the constant temperature and humidity test chamber is to facilitate customer use and ensure the accuracy of the test. For example, during low-temperature testing, the observation window glass is cold, and when it encounters warm air at room temperature, frost will form, condensing on the observation window glass, making it impossible for us to use the observation window to observe the real-time status of our product testing.

Therefore, in order to avoid this phenomenon, our company has a lead line to the inside of the test chamber door, and heating wires are buried around the observation window and its surroundings. The foam is fixed inside the chamber door. When the low-temperature test is performed, the relay will work, and the heating wires will generate heat energy, preheating the door of the test chamber to achieve a normal temperature state. In this way, frost will not form during low-temperature testing, making it easier for customers to observe.

As the constant temperature and humidity test chamber is a high-tech product, we kindly remind customers to read the instruction manual thoroughly after purchasing. In addition, the insulation layer of the equipment is 100mm thick. When high-temperature testing is performed, there is absolutely no heat leakage, and the constant temperature and humidity test chamber door will not get hot.
