Correct use of the constant temperature and humidity chamber and working environment experimental equipment can not only provide accurate basis for the constant humidity and constant temperature chamber test personnel, but also correctly place the experimental samples. The placement of the experimental samples should be more than 10cm away from the wall of the box, and multiple samples should be placed should be placed on the same plane as possible.

The sample should not block the air outlet and return air outlet, and a certain interval should be reserved for the temperature and humidity sensors. Make sure the experimental temperature is correct. And make the environmental experimental equipment operate normally for a long time, and prolong the service life of the equipment.

First, when conducting an environmental experiment, you must understand the skills and capabilities required for the experiment, as well as the structure of the device, especially the operation and function of the controller.

It is also necessary to read the operation manual of the experimental equipment carefully to avoid abnormal operation of the experimental equipment due to operating errors, thereby damaging the experimental samples and erroneous experimental data.

Secondly, it is necessary to choose the experimental equipment reasonably.

In order to ensure the normal operation of the experiment, a reasonable share must be maintained according to the available capacity of the experimental chamber. For experiments with heated samples, the volume should not be greater than one tenth of the useful volume of the experimental chamber. For non-heated test samples, the volume should not be larger than It should be greater than one-fifth of the useful volume of the constant temperature and humidity machine.
