In our work and life, the role of constant temperature humidity test chamber can not be underestimated. It can simulate a variety of environmental conditions, providing important support for our product testing, scientific research and so on. However, if it is used incorrectly, it will not only affect the experimental results, but also may damage the equipment, and even bring safety hazards.
First of all, let's talk about the problem of water. Constant temperature humidity test chamber water available distilled water, deionised water or pure water, do not use tap water Oh! Because tap water contains more impurities, will affect the effect of the experiment and the service life of the machine. This must be borne in mind, do not make a big mistake because of the convenience of the moment.
Next, before the end of the device, wiring, absolutely not allowed to turn on the power, otherwise it is easy to electrocute or malfunction and fault. This is no joke, safety first is always the most important. And, constant temperature and humidity test box wiring must be correct, and must be grounded, so as to ensure the safety of our use.
And oh, the operator of the test box operation and performance to be familiar with. If you do not understand the equipment, it is easy to make operational errors. We can improve our operation level by reading the manual, attending training and so on.
In addition, the ventilation of the test chamber also needs us to do regular cleaning to remove places where dust is likely to accumulate. This will ensure the normal operation of the equipment and extend the service life of the equipment.
Constant temperature and humidity test chamber using wet bulb gauze is not any gauze can be replaced. We have to use special wet bulb gauze, so as to ensure the accuracy of the measurement.
When the test chamber is doing high temperature test, the temperature inside the chamber will be very high. If you need to open the door of the box during or after the test, you must be especially careful so as not to be burned. Similarly, when doing a low-temperature test, the temperature inside the chamber will be very low, and care must be taken when opening the door to prevent frostbite.
And, although the equipment has sound anti-electrocution measures, we should pay special attention to the control system of electrical appliances in the case of work. Please do not connect the power supply of the test article into the equipment, otherwise it will increase the load of the power supply. Unless the equipment has a test article power supply interface, at the same time, it is prohibited to test with flammable, explosive, highly corrosive items, and do not carry or repair the equipment in the energised state or during operation.
Constant temperature and humidity test chamber should be used in the environment below 30 ° C to ensure the normal operation of the equipment. At the same time, chemicals are prohibited from contacting the equipment to avoid damage to the equipment.
During use, we should ensure that the power supply within the rated voltage range is provided to avoid malfunction. When installing, we have to make sure that the wiring is correct and grounded, poor grounding may lead to electric shock. We also need to ensure that the ventilation holes of the constant temperature humidity test chamber are kept open to avoid unnecessary failures. When cleaning the instrument, make sure you use a dry cloth, do not use alcohol, petrol or other organic solvents.
When opening the door of the constant temperature and humidity test chamber and placing the samples on the sample rack of the chamber, make sure that there is a certain distance between the samples and the wall of the chamber, and that the air around the samples is circulating. At the same time, to check the constant temperature and humidity test box right below the water tank water level line is not more than 3/5, if less than 3/5, add water in a timely manner.
When confirming the test conditions, it is necessary to confirm the environmental conditions such as temperature, humidity, time, etc. required for the test, as well as the precision and stability required for the test, according to the test requirements. When preparing test samples, the test samples should be prepared according to the test type and parameters. Operators need to understand the use and operation of the test chamber, and calibrate the test instrument before conducting the test to ensure its accuracy and precision. Also regularly check whether the water tank storage is sufficient, if the water is insufficient to add sufficient water to the equipment according to the test demand, to avoid stopping the water in the test process. In order to ensure the normal operation of the test chamber, the need for maintenance of the equipment, including cleaning equipment, check the status of the instrument, adjust the stability and accuracy of the instrument.
In short, the correct use of constant temperature and humidity test chamber requires us to pay attention to many details. Only if we take it seriously, can we give full play to the role of the equipment and bring more convenience to our work and life.
