    Temperature   balance method: Adopting static balance technology, namely the balance method   of "cooling process without heating" and "heating process   without cooling", it is different from the traditional dynamic balance   technology of "cold and hot dynamic balance" of high-power   refrigeration against high-power heating

    Technique, that   is, when the compressor needs to be turned on (the central controller   automatically determines whether to turn on the compressor based on the   working conditions)

    The central   controller adjusts the refrigerant flow rate according to different   temperature points to control the cooling capacity, ensuring that the   equipment operates in a relatively low power consumption state at all times

    External USB port: can be directly connected to the printer,   enabling local data to be printed online,

     

    It is easy to export historical curves and other data using a   USB port and a USB flash drive.

     

    External LAN standard network interface: Without the need for   dedicated server configuration, it can be easily connected to the company's   computer local area network. A maximum of 16 devices can be connected and   monitored, making it convenient and fast.

    Equipped with RS-485 or RS232 standard communication interfaces,   it can be controlled and managed online with computers Equipped with all   Chinese upper computer software and providing communication protocols The   upper computer acquisition program is written by the user, which includes   protocols for opening temperature signals, various alarm and protection   signals, and fault/shutdown status signals of the test box, in order to   upload the temperature box temperature in real-time to the upper computer   monitoring system. At the same time, a system fault and abnormal alarm   digital node is provided. The upper computer monitoring system needs to   collect the fault/shutdown signals of the test box, in order to achieve   synchronous power-off between the sample and the temperature and humidity box   through the main controller

    3. Real time monitoring can achieve: simultaneously monitoring   the operation status of 1-16 controllers, such as monitoring real-time data   of controllers, signal point status, actual output status, etc
