Humidity Chamber

Temperature and humidity balance box is used to adjust the test box with constant temperature and humidity, humidity is the key factor that affects the strength of carton, the carton is sensitive to temperature and humidity, temperature and humidity, moisture content of the carton is different. Therefore, we carry out the carton transport packaging test must be carried out before the temperature and humidity balance of packages, moisture content until the carton will no longer change processing time of sample generally takes more than 8 h (temperature: 23 degrees Celsius, humidity 50%RH, can also according to the actual conditions of temperature and humidity storage and transportation), to ensure that the test the package of objective and reliable. Constant temperature and humidity test box can also be used for paper and board temperature and humidity regulation and other materials environmental temperature and humidity test.

Product features

The new fluorine free design adopts wet and dry ball type multi-function multi section programmable temperature and humidity controller, fuzzy PID controller, temperature control, humidity precision, small fluctuation.

Imported 304 mirror stainless steel inner container, four corners and half arc transition, shelf support can be freely loaded and unloaded, easy to clean the box.

The user set parameters can be automatically stored in the event of a sudden power failure and run the original setup program after power on.

International brands of compressors and recycling fans, environmental protection refrigerants (R134a), high efficiency, low energy consumption, and promote energy saving.

Unique air circulation system, ensure the temperature and humidity of the workshop is even, and the diameter is 25mm. The test hole is easy to operate and test.

Independent temperature alarm system, more than the limit temperature is automatically interrupted operation, and sound and light alarm, prompting operators to ensure the safe operation of the experiment, without accidents.

High temperature, low and over temperature alarm, compressor overheating, overcurrent, overload protection, fan overheating protection, water shortage protection.

A printer or 485 communication interface can be connected and displayed by computer, and the temperature, humidity and time curves are printed to provide a strong guarantee for the storage and playback of the data stored in the test process.

With large screen touch screen screen, the screen is easy to operate and easy to edit.

The controller interface design English available instant operation graph by screen display.

With 100 sets of programs, 1000 segments, 999 cycle steps, each time set the maximum value of 99 hours, 59 minutes.

After the data and test conditions are input, the controller has the function of screen locking and stops the human touch.

With P.I.D automatic calculation function, the temperature and humidity change conditions can be corrected immediately, and the temperature and humidity control can be more precise and stable.

With RS-232 or RS-485 communication interface, you can design programs on the computer, monitor the test process, and the implementation of switching machines and other functions.
