4 Supply air circulation system:

1. Adopt a multi blade centrifugal circulating fan, reinforced with an axis and aluminum alloy rotating blades that are resistant to high and low temperatures, to achieve forced convection

2. FLOW THOW air supply method; Horizontal diffusion, vertical heat exchange, arc-shaped cycle

3. Adjustable side blowing air outlet and protective net return air outlet

Five controller:

1.7-inch high-definition color touch screen, with 65000 true colors and a resolution of 800 * 480. The core controller is PLC, which has a long service life, strong anti-interference ability, high control accuracy, fast data processing speed, and multiple signal combination relays (transistors) output. The signals can be logically processed (NOT, AND, OR, NOR, XOR)

2. Temperature and humidity 2-channel input, independently controlled, capable of 10 point linear slope compensation for each temperature and humidity of nonlinear sensors; There are two control modes for each channel: fixed value/program fixed value. The maximum time can be set to 9999999 hours; Program editing and looping, the program can be programmed with 100 groups, each consisting of 100 segments, supporting free combination programming to output high difficulty controls such as serial and parallel.

3. Equipped with Chinese character input function, edit and input manufacturer information, fault alarm name, test name, data group name, etc

4. Communication function: The instrument is equipped with a USB interface, which supports USB storage, exporting historical curves, and data functions, and can be viewed and printed using computer software

5. Interface type: Chinese/English can be freely selected and switched; Temperature and humidity control and single temperature control display can be freely selected

6. Compressor delay function; Manual, automatic, and timed shutdown functions; Appointment activation function

7. 4 internal alarms and 8 external alarm functions can be customized, and the external input DI alarm signal can be freely switched between normally closed or normally open signal modes

8. The instrument is equipped with an alarm buzzer, which can freely set whether to delay the output when the alarm is triggered, how long to delay, whether to stop the machine, whether the buzzer will sound an alarm, whether the alarm interface will pop up, whether to output external alarm points, and other functions; In case of hardware failure at the input/output point, the backup function of moving the point; Water shortage prompt, automatic replenishment; Automatic alarms for overheating, overload, etc

9. The controller can display the current operating status in real time, such as set values, real-time values, running time, number of groups and segments, number of cycles, and other main process parameters, as well as statistical data; Various control parameters can be set arbitrarily

10. Real time display of temperature and humidity PV/SP curves; And it can also query historical curves
