The difference between digital display high temperature test box and drying box

Difference betweendigital display high temperature test box and drying box
In addition to the function of drying oven, the high temperature test box is also mainly used for high temperature performance test of bridge inspection, electrical, electronic and other non-flammable and explosive items
.

The artificial climate simulation system produced by our company provides an intelligent environment simulation test system for the durability of bridge engineering materials under various environmental conditions and different test methods
.

2.
The main technical indicators of the products are different.
The temperature uniformity of the drying box is not greater than ±2.
5% of the higher operating temperature, and the temperature uniformity of the test box is not greater than 2°C (when the test temperature is 200°C)
.

Although it is only a difference in sign, the difference in value is doubled
.

As far as 450°C is concerned, the temperature of any two points in the drying oven can differ by 22.
5°C, while the test chamber cannot exceed 9°C.
3.
The difficulty of product manufacturing varies.
On the surface, there is not much difference between the two
.

The actual difficulty is that when the air is heated to a high temperature above 350°C, the movement of the gas becomes very difficult to control.
Even under the condition of forced blowing, the flow of the gas is still turbulent, so the design requirements for the air duct
.

The air duct should vary for different studio sizes
.

In order to obtain reasonable data, it is often necessary to go through repeated experiments
.

In order to obtain a higher uniformity index, the cost of manufacturing the test chamber is much larger than that of the drying chamber
.

 　　4.
The product control system is different.
Because the drying box has a low index, it is enough to use an ordinary instrument
.

The test box uses an instrument with PID calculation function, and sometimes the instrument can run the program for the needs of the test
.

When in use, the PID value of the high temperature section can be obtained through self-tuning, and sometimes the value obtained by the self-tuning needs to be modified by the operator
.

 　　By reading the full text, we can know that there are four differences between the digital display high temperature test box and the drying box.
First, the product uses are different, the second is the main technical indicators of the product, the third is the difficulty of product manufacturing, and the fourth is the product control system.
The difference, when choosing, should be combined with the needs to buy, I hope to help you
