Analysis of vertical and benchtop constant temperature and humidity test chambers

The constant temperature and humidity test chamber can be divided into “desktop” and “vertical”. The main difference is that the temperature and humidity can be different, so the temperature will be different. The vertical can be used for low temperature and dry below normal temperature. The table top can only be used for temperatures above ambient temperature and high humidity.
Analysis of vertical and benchtop constant temperature and humidity test chambers:

In the process of contact with customers, because we know that many customers can't distinguish between the desktop and vertical concepts of constant temperature and humidity chambers, Poussin makes a detailed introduction here, hoping that users who want to buy constant temperature and humidity boxes are It is helpful when choosing a structure.

The constant temperature and humidity chambers are conventional and can be divided into "desktop" and "vertical". The main difference is that the temperature and humidity can be different, so the temperature will be different. The vertical one can be used below normal temperature. The low temperature and dryness of the table top can only be done at temperatures above normal temperature and high humidity.


The same point of the two: the outer box is treated with high-quality matte line SUS304# stainless steel "target=_blank> stainless steel plate or electrostatic spraying treatment, the inner liner is imported (SUS#304) high quality mirror stainless steel" target=_blank>stainless steel plate And the plane has no reaction handle, the operation is easier, safe and reliable; the bright, wide-view observation window: the fluorescent lamp is used to keep the box bright, and the multi-layer hollow tempered glass is used, and the inner glued sheet type conductive film (the process can be clearly observed) . Have a complete safety device: If an abnormal situation occurs, the fault status and power supply are immediately displayed on the screen to ensure the safety of the machine itself, the tested product and the user.


(1) Vertical introduction:

It is suitable for investigating the moisture resistance of electrical and electronic products, components, parts and materials under different temperature and humidity conditions. It can also be used as an adaptability test for storage, transportation and use in high and low temperature environments.



Equipped with a refrigeration system, the temperature can be 0 ° C ~ 100 ° C, the relative humidity range is also wide, humidity range: 30 ~ 98% RH. But the price is also relatively high.

Control instrument is: imported Japanese (OYO) instrument

The inner tank volume (capacity) of the vertical constant temperature and humidity chamber generally does not exceed 1000L.


(2) Desktop introduction:

The desktop constant temperature and humidity chamber is also called a desktop constant temperature and humidity test chamber to detect the parameters and performance of the product after a constant test temperature environment change.



Temperature range: RT+10°C～100°C, there is no refrigeration system, only the temperature from room temperature to 100°C; the relative humidity range can only be 85~98% RH. And affordable.

Control instrument is: domestic digital display Yuyao table

The test machine is compact in design, easy to place, easy to learn, new and perfect arc shape design, high-quality appearance, beautiful appearance.
