use

This constant temperature and humidity environment Test Chamber can simulate a variety of temperature and humidity environments, mainly used to test the performance of materials in various environments and test the heat resistance, cold resistance, dry resistance, humidity resistance of various materials. It is suitable for testing the quality of electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, aerospace and other products.

Control mode: Balanced temperature and humidity control system (BTHC) is adopted, the induction system transmits the actual data in the Test Chamber to the controller, and the controller balances the output power of the temperature and humidity system through the control SSR and multi-segment intelligent output, so as to ensure that the temperature and humidity in the Test Chamber are fully stable, and has the function of energy saving, which reduces the power of the instrument to a greater extent and ensures the long-term accurate and stable operation of the instrument.

Features

1. The product has beautiful appearance, reasonable structure, precise process, simple and convenient operation and stable and reliable performance.

2. The controller adopts a large color LCD man-machine touch dialogue LCD man-machine interface controller, which is simple to operate, easy to learn, stable and reliable, and displays the complete system operation status, execution and setting program curve in Chinese and English, and can realize RS232 computer interface docking, and directly control the instrument remotely through the computer.

3. Compressor is used in the refrigeration circulation system: the original imported Japanese "Sanyo" brand fully enclosed compressor (purchased by Taikang compressor in France), all components are imported components, respectively from Japan, France, the United States, Italy and other origins, and the refrigerant adopts American environmentally friendly refrigerant (R23A, R404A).

4. There is a test hole with a diameter of 50mm on the left side of the Test Chamber.

5. It has fully automatic, high-precision system loop, any part action, P.L.C locking processing, all of which are controlled by P.I.D automatic calculation, and the temperature of the whole area has high precision and high stability.

6. Specially designed air circulation system and sensor system, the air outlet is detected and controlled by the return air outlet sensor, so as to ensure the uniformity of temperature in the Test Chamber and avoid any dead ends.

7. The use of enlarged observation window, 4 layers of empty tempered glass, a broader field of vision.

8. The instrument has a comprehensive protection system, power overload protection, leakage protection, control loop overload, short circuit protection, compressor protection, grounding protection, overtemperature protection, alarm sound prompt, etc., when any abnormal situation occurs, the screen will automatically display the fault point and cause and automatically shut down.

Temperature and humidity control range curve

Heating system

Multi-section heating tube with PID module is used to ensure stable temperature, and sectional heating is used to fully save energy.

The heating pipe is made of high-temperature-resistant and corrosion-resistant alloy pipe, which prolongs the service life

Humidification system

The round split humidifier avoids the freezing phenomenon of the sink humidifier during the low temperature test.

The humidification tube is made of special alloy, which can be boiled for more than 1 hour when the instrument is faulty and short of water, and the high temperature alarm module effectively prolongs the service life of the humidification system. Built-in Water Tank, drawer-type water box, convenient and beautiful.

It has a water circulation system, which saves 40% of water.

It has a water filtration system to avoid clogging of the humidification system as much as possible and reduce the frequency of cleaning.

Air circulation system

1. High resistance air circulation motor

2. Multi-wing fan blades

3. Specially designed fan forced air supply circulation system

Refrigeration system

Compressor: original imported Japanese "Sanyo" brand fully hermetic compressor (French Taikang compressor purchase)

Condenser: Fin-type multi-stage condenser with integral forced cooling fan

Evaporator: Fin-type multi-stage automatic load capacity adjustment evaporator, with energy-saving control valve, realizes forced refrigeration and constant temperature refrigeration segmented control

Refrigerant: The United States imports new environmentally friendly refrigerants R404A and R23A to achieve zero pollution to the environment
