Precautions for operating walk-in temperature and humidity Environmental Test chamber

According to different names, the walk-in constant temperature and humidity test chamber can also be called constant temperature and humidity chamber, high and low temperature alternating humidity and heat test chamber, etc. It is mainly used for the detection of environmental resistance test materials. It adopts the originally imported controller, which can choose the test mode suitable for you according to your own use requirements.

At the same time, because the walk-in temperature and humidity environmental test chamber is an environmental test chamber that allows operators to enter, it is still dangerous. In order to avoid the occurrence of safety accidents, when we choose to use this walk-in environmental test chamber, we choose to determine whether we are meeting the following conditions.

1. When we use this walk-in temperature and humidity environmental test chamber, we must first determine whether the door is locked, so as to better ensure that the set environment cannot be reached due to temperature leakage in the walk-in test chamber. But when locking the door of the test chamber, make sure that there are no other people in the studio, because not all high and low temperature alternating humidity and heat test chambers can open the door from outside the test chamber.
2. If you need to open the door to conduct the test during the test, you must first do the protection to prevent injury caused by the hot or cold air rushing out of the studio. At the same time, it is also necessary to ensure that there is sufficient oxygen in the studio, which can ensure that the staff debugs internally, otherwise there may be a lack of oxygen.
3. When the walk-in temperature and humidity environmental test chamber is working normally, the connected power supply should be stable at 380V, so if the person gets an electric shock, it is best to carefully check the power cord and other electrical parts of the device after each use. If problems arise, they must be resolved in time before they can be further tested using a walk-in constant temperature and humidity test chamber.

The above information is about how to correctly use the walk-in constant temperature and humidity test chamber for testing, and hope to help those in need. In the process of using environmental test chambers or battery test chambers for testing, we must first fully understand the operation process of the test chambers, so as to ensure the accuracy of the experimental data and ensure our own personal safety.
