A new generation of high and low temperature (alternating) heat chamber, set the company many years of successful experience in the design of the box, the spirit of human design, starting from the actual needs of customers in every detail to meet customer requirements, providing customers high-quality products. Features: ◆ Humanized design ● new CFC-free design, so you always walk in front of a healthy life. ● using wet and dry bulb or capacitive multi-purpose multi-stage programmable temperature and humidity control, fuzzy PID controller, precise control of temperature and humidity fluctuations small. ● Long life inlet temperature and humidity control, high-precision CFL20 word × 6 line LCD display, keyboard input, easy to operate. ● left side of the box with a diameter of 25mm or 50mm test hole, easy operation and temperature measurement experiment. ● Built-in sink can be pulled out of water, easy to use. ◆ Quality Assurance ● International brand compressor and circulating fan, the temperature distribution. Environmentally friendly refrigerant (R134a) high efficiency, low energy consumption, promote energy conservation. ● Unique air circulation system to ensure uniform temperature and humidity work. ● imported 304 mirror stainless steel, semi-circular corners over, shelf support handling free, easy cleaning inside the box. ● Multi-segment programmable control, can simplify complex testing process, truly automatic control and operation. ◆ security features ● Independent limit temperature alarm system, exceeds the limit temperature is automatically interrupted run, and sound and light alarm operator. Ensure the safe operation of experiment is not an accident. ● high temperature, low and over-temperature alarm. ● compressor overheating, over current, overload protection, fans thermal protection, water protection. ◆ convenient data processing (optional) ● 485 can be connected to a printer or interface with USB data transfer interface (U disk), a computer display, and print temperature, humidity and time curve, provide a strong guarantee for the trial process data storage and playback . Programmable touch screen controller :( optional) ● with color LCD touch-control screen, menu-driven user interface, observe intuitive and easy to operate. ● English user interface can be arbitrarily chosen, the screen can display real-time temperature and humidity operating curve. ● 1000 100 programs can be preset step 999 cycles, each time setting a maximum of 99 hours and 59 minutes. ● has a screen lock function, to avoid human touch and change the test data or downtime. ● With PID automatic calculation function, you can change the temperature and humidity conditions are corrected immediately, so that more precise and stable temperature and humidity control. ● with RS-232 or RS-485 communication interface, the program can be designed to monitor the testing process and execute switch functions on the computer. ● Install professional control software on your computer, enabling simultaneous monitoring and control 9 devices. ● Real-time analysis of data stored on the computer and to form an Excel document or Word document easy to print.
