CHINA Plastic programmable Humidity Chamber constant temperature and humidity testing machine -20 ℃~ 150 ℃/100L

Introduction

The high-low temperature damp-heat alternating Test Chamber is mainly used to test the performance of materials in various environments and to test the heat resistance, cold resistance, dry resistance and 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 by controlling SSR and multi-stage intelligent output, so as to ensure that the temperature and humidity in the Test Chamber are fully stable, and has energy-saving functions, 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.Control the instrument remotely directly from your computer.

3. Compressor is used in the refrigeration circulation system: the original imported Japanese "Sanyo" brand fully enclosed compressor (French Taikang compressor purchase), each component is imported from Japan, France, the United States, Italy and other origins, and the refrigerant adopts the United States 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 a fully automatic, high-precision system loop, any part action, P.L.C locking processing, and all P.I.D automatic

Calculated control, 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 to ensure the test

The temperature uniformity in the box avoids any dead ends.

7. Adopt enlarged observation window and 4 layers of hollow tempered glass, which has 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, over-temperature protection, alarm sound prompt, etc., when any abnormal situation occurs, the screen will automatically display the fault point and the cause and automatically shut down.
