| Box structure characteristics |
|
The box body of the constant temperature and humidity test box is processed and formed by CNC machine tools. The appearance is beautiful and novel, and the non-reaction handle is adopted for easy operation.
The inner shell of the box is made of imported high-grade stainless steel (SUS304) mirror panel or 304B argon arc welding, and the outer shell of the box is made of A3 steel plate spray.
Constant temperature and humidity test chamber temperature "Youyi Control" brand temperature meter imported from Japan, 7-inch high-definition true color LCD touch screen, simple screen operation, easy program editing, no key input, direct touch option on the screen. (South Korea TEMI880 instrument)
The operation interface of the controller is available in Chinese and English, and the real-time operation curve can be displayed on the screen.
It has a capacity of 100 groups of programs, 1000 segments and 999 cycle steps, and the maximum value of each segment of time is 99 hours and 59 minutes.
After data and test conditions are input, the controller has a screen lock function to avoid shutdown due to human touch.
With RS-232 or RS-485 communication interface, you can design programs on the computer, monitor the test process and perform functions such as automatic power on and off.
With the function of automatic calculation, the temperature and humidity change conditions can be corrected immediately, making the temperature and humidity control more accurate and stable.
The large observation window is equipped with illuminators to keep the inside of the box bright, and double-layer glass is used to clearly observe the situation inside the box at any time.
Equipped with an independent temperature limit alarm system, which automatically interrupts when the temperature exceeds the limit, ensuring the safe operation of the experiment without accidents.
Optional recorder, the printer can print and record the setting parameters and scan out the temperature and humidity curve, 4-20mA standard signal.
The left side of the box is equipped with a 50mm diameter test hole.
