3. Control system
, temperature and humidity controller Using the original imported (South Korea) color touch-type intelligent programmable temperature and humidity controller, the program is easy to edit and the screen operation is simple.
, Chinese and English LCD touch panel, screen dialogue input data, temperature and humidity can be programmable at the same time, backlight segments are adjustable, curve display, set value/display value curve.
, precision., resolution.℃.
, Temperature sensor platinum resistance sensor, high accuracy.
, multiple sets of control functions, precise monitoring functions, and displayed on the screen in the form of data.
. It has the function of automatic calculation, which can immediately correct the temperature and humidity changing conditions, making the temperature and humidity control more accurate and stable.
The controller has an automatic screen saver function, which can better protect the LCD screen and extend its life under long-term operation.
It has a group program, each group of segments, and the capacity of each segment's cyclic steps. The maximum value set for each period of time is.
The temperature control adopts + system coordinated control on the same channel.
After entering the data, data and test conditions, the controller has a screen lock function to avoid shutdown due to human touch.
, control mode heat balance temperature adjustment mode, all electrical appliances adopt (Schneider) series products.
, with or remote communication interface, can design programs on the computer, monitor the test process and perform functions such as automatic power on and off.


4. Box material
Perfect shape design, arc shape and surface spray treatment, high-quality appearance, more clean and beautiful.
The box shell is made of high-quality steel plate CNC machine tools, with a beautiful and elegant shape, and the surface of the shell is spray-painted.
The inner tank of the box is made of high-grade () stainless steel plate.
. The insulation material is high-density glass fiber cotton, and the thickness of the insulation cotton is /.
The observation window is made of multi-layer hollow tempered glass, with built-in lighting, and the inner glued conductive film is heated and defrosted to clearly observe the test process.
The temperature circulation system adopts a temperature-resistant and low-noise air-conditioning motor and a multi-blade centrifugal wind wheel.
Double-layer high-temperature-resistant and inflatable sealing strips are used between the door and the box to ensure the sealing of the test area.
There is one test hole on the left side of the box, which can be used for external test power lines or signal lines (if the hole diameter or number of holes increases, please explain).
The bottom of the high and low temperature alternating heat and humidity test chamber adopts high-quality fixed movable wheels for easy movement.
5. Refrigeration system
The compressor is fully enclosed and original from France Taikang.
, condensation mode forced air cooling.
, refrigeration mode single (double) machine refrigeration.
, Dehumidification adopts laminar flow contact dehumidification method at dew point temperature of evaporator coil.
, solenoid valves, oil separators, filter dryers, repair valves, refrigerant flow windows, and liquid storage cylinders are all imported original parts.
6. Heating and humidification system
Heating uses far-infrared nickel alloy high-speed heating electric heater.
High temperature, low temperature and damp heat are completely independent systems and do not affect each other.
, External stainless steel humidification tube, steam humidifier has the function of energy saving and consumption reduction, and has automatic water level compensation.
The humidification system pipeline is separated from the control circuit, power supply, controller, and circuit board, which can avoid affecting the circuit due to pipeline leakage and improve safety.
7. Safety protection system
Protection against overall equipment over-temperature, refrigeration system overload, refrigeration system over-pressure, leakage, water shortage, operation instructions, automatic shutdown after fault alarm, etc.
Free door-to-door delivery. After the installation and debugging of the equipment, relevant technical personnel will be provided with corresponding basic operation training. Two-year warranty and lifetime maintenance
