Chemical experimenters will use the test tube to measure the amount of chemical water for relative testing. In the process of using the constant temperature and humidity test chamber or during the test, it is necessary to make certain treatment according to the nominal value. As an important feature of the constant temperature and humidity test chamber for the nominal value of the working environment parameters, it is also the basis for calculating the deviation of the environmental parameters. However, it is necessary to make the basic settings when performing the verification work. However, the actual operator's understanding of its nominal value is limited, so let's clearly explain the nominal value.
First, the main characteristic is the nominal value, which is mainly marked on the gauge with its characteristic or guiding the use of the value;
Second, the main characteristics of the nominal value: it is a measurement result and is owned by the measuring instrument, but also belongs to a known value;
3. For the role of the nominal value in the constant temperature and humidity test chamber and the verification work, the environmental conditions required in the environmental test are provided by the test chamber, but the test method standard is the nominal of the environmental conditions. The value is an ideal value, but many factors are generated during its actual test, which affects the actual value of the environmental conditions provided by the test chamber. The nominal value cannot be reached only when it is close to the nominal value, and the degree of proximity depends on the accuracy of the system controlled by the test chamber. The other main functions are reflected in the following two aspects:
1. The nominal value is the basis for setting the value of the system controlled by the test box;
2. The nominal value is the basis for calculating the environmental condition deviation at each point of the test equipment working space;
The relevant knowledge points about the nominal value are expected to be understood, because environmental conditions and test conditions may be involved, but the nominal value of the constant temperature and humidity test chamber is an important point for the relevant calculation of the experimental results.
Why is Sit Stand Desk becoming more and more popular? Sit stand desk is not only a desk. Using sit and stand desk station interchange for office can make sense of life, reduce fat, enhance energy, reduce pain, improve work efficiency and improve team cooperation ability.
1.5-2.5mm thick cold rolled steel plate with high mechanical strength, smooth surface and uniform thickness,Double motor balanced drive, lifting the whole table without shaking. The rising and falling sound is less than 45 dB, which is lower than that of keyboard typing.
The color of ergonomic Standing Desk frame: black, white, gray, and can be customized; it can be matched with different color panels, reflecting the modern design of the product.
