What to pay attention to when using high and low temperature test chambers:

1. Check whether the switching power supply is stable before starting.

2. In order to better avoid electric shock accidents or cause wrong operation and common faults, please do not connect to the switching power supply before installation and wiring are completed.

3. In order to prevent common failures of the equipment in the spray paint high and low temperature test chamber, please show the switching power supply within the rated current range.

4. The high and low temperature test chamber is non-explosion-proof equipment, so it cannot be used in an environment with flammable or combustible vapors.

5. When the high and low temperature test chamber is running, please do not need to open the tailgate as much as possible. Opening it at a high temperature is likely to be harmful to the actual operating staff. It can cause burns. Turning it on at ultra-low temperature is likely to cause freezing of the workers, and it is likely to cause the air conditioner evaporator to freeze, which will endanger the actual cooling effect. If you must turn it on, please do a good job of safety protection.

Frequently Asked Questions Cleared

1. High and low temperature test. In the high temperature experiment, if the temperature change does not reach the experimental temperature value, the household appliance system software can be checked, and the failure detection one by one. If the temperature rises relatively slowly, you need to query the air-breathing system. See if the adjustment partition of the air circulation system is open and everything is normal. On the contrary, check if the motor of the air circulation system is running normally. If the temperature overshoot is strong, then the main parameters of the PID setting must be set. If the temperature is immediately Rising, temperature protection, then, the control panel has a common failure, and the control instrument must be replaced.

2. If the ultra-low temperature fails to reach the experimental index value, then you need to observe the temperature change. Is the temperature drop relatively slow, or the temperature has a trend of warming up after the temperature reaches a certain value. The first one needs to be checked for ultra-low temperature experiments Was the personal studio air-dried before, so that the personal studio was kept dry, and then the experimental samples were put into the working room to do the experiment? Is the experimental sample in the working room too much placed in the working room? The wind in the middle room cannot sufficiently circulate the system. After the reasons are cleared, it is necessary to consider whether it is a common fault in the refrigeration unit, and then you need to ask the manufacturer’s technical professional staff to carry out maintenance. The situation is caused by the application of machinery and equipment in a poor natural environment. The working temperature of the machinery and equipment and the place where it is placed (the distance between the back of the shell and the wall) must meet the requirements.

3. In the cold and wet experiment, it appears that the specific environmental humidity will reach 100% or the specific environmental humidity is very far from the overall target environmental humidity, and the standard value is much lower. The previous situation: it may be dry bulb temperature sensing If the sand cloth on the device is dry, it is necessary to check whether there is little water in the stainless steel tank of the dry bulb temperature sensor. The water level line in the stainless steel tank is automatically controlled by a liquid level controller. Check the liquid level controller. Is the power supply of the water supply equipment normal? Is everything normal during the operation of the liquid level controller? Another possibility is that the dry bulb temperature shabu will harden due to the long use time or the purity of the power supply water body. , So that the sand cloth cannot digest and absorb water and become dry. If the sand cloth is removed or cleaned, the above situation can be removed. The latter situation is mainly that the humidification system software is not working, and the water supply equipment of the humidification system software is inquired, Is there a certain amount of water flow in the water supply equipment, whether the water level line operation of the water level line of the humidification heating furnace is normal, and whether the water level line in the humidification heating furnace is normal.

What is the difference in the function of the high and low temperature test chamber, the temperature control environment test box, and the humidity control environment test box?

1: Although they are all environmental test chambers, the natural environment in which they accurately measure raw materials is different. For example, the temperature-controlled environmental test chamber can ensure that the raw materials are tested under a condition where the temperature remains unchanged, whether it is high temperature to 300 ℃ or ultra-low temperature to minus ℃, it can ensure that the temperature around the raw material will not change.

However, it cannot guarantee the environmental humidity around the raw materials. The humidity-controlled environment test box just fills in the shortcomings of the temperature-controlled environment test box. The humidity-controlled environment test box can ensure that a certain environmental humidity around the raw materials does not change, and is convenient for accurately measuring the environmental humidity of the raw materials into the category. The high and low temperature test box just combines the advantages of the above two environmental test boxes, which not only has the functions of high temperature, ultra-low temperature, and environmental humidity, but also independent high-temperature experiments and ultra-low temperature experiments.

Because it has such a powerful effect, it is called a piece of indispensable experimental equipment in the industry.

2: Above is the difference between them, and naturally the price is also different. Relative to the high and low temperature test chamber, the price of the temperature control environment test box and the humidity control environment test box is not as expensive as the previous one, and because of the powerful effect, there must be a difference in the price.
