    This I don't think there is a very well-established definition or norm! Liuqin Technology is an enterprise designed and manufactured by professionals for constant temperature and humidity system software.
    It encounters a variety of customers, some of which basically have no regulations.
    If they can be roughly manipulated, some regulations are very high; basic theory If there is a laboratory with constant temperature and humidity function, it can be called "a constant temperature and humidity laboratory", but during the operation, it is usually based on the temperature and humidity standards of your products or machinery and equipment to clarify your constant temperature.
    What is the constant humidity standard! However, when many people choose a constant temperature and humidity unit, they confuse many key index values, and even the essence is not clear; some of these are not clearly defined in this area soon, and some are represented by some black-hearted regions.
    Or the manufacturer has cheated, such as "fluctuation, precision, precision, error", many customers are not clear about the essence of these many index values, I will show you about it below: 1.
    Fluctuation: refers to the machine During the operation of the equipment or instrument panel, the error between the actual measured value (PV) of the instrument panel and the overall target preset value (SP/SV); the calculation time of this value is different, and there are different specifications.
    In the environmental test equipment, it is to The measurement starts 15 minutes after the temperature, and the constant temperature and humidity machine (some are called constant temperature and humidity air conditioners or precision air conditioners have no established time).
    The term precision is confusing
    .

    2.
    Precision: It refers to the error between the mean value and the maximum or bottom point of 9 standard test cases in a spatial graph; in addition to the linearity of machinery and equipment, this index value also includes the design of the air circulation system of the system software.
    The idea is that in the constant temperature and humidity system software, this standard value is an index value that is very difficult to maintain, especially in the key.
    Regulations, and then exceed their own goals, and because many customers do not understand the difference between the two, they do not know how to accept the project when they accept the project! 3.
    Precision: It is usually used as the indicator value of the controller and the instrument panel as a key main parameter to distinguish its working ability; but for the setting, it is only the marked value of the displayed information, such as 20.
    0 and 20.
    00 , Although it is necessary to control the fluctuation, the key constant index value of the machine is usually confused with the fluctuation index value
    .

    4.
    Error: refers to the error between the precise measurement value and the specific value; this standard value is usually presented by third-party platform measurement and testing companies, and is mainly used for the characteristics of constant controllers and instrument panels; many people with ulterior motives associate this standard value with precision.

    .

    In general, when everything is normal, when a customer prepares a set of constant temperature and humidity laboratory in advance, the key index values ​​are fluctuation and precision, which are the two most critical specific index values ​​of the system software.
    The precision and error of the instrument panel are usually clarified by the supplying manufacturer, and the insider of the customer will suffice
    .

    People don't expect to harm the end user with things like "Anyway, the application side doesn't understand, let's get it cheap"!
