CHINA semiconductor Humidity Chamber paint panel -70 ℃~ 150 ℃/225L

Introduction

The high-low temperature and humidity alternating Test Chamber is mainly used to test the performance of materials in various environments and to test the heat resistance, cold resistance, dryness resistance and moisture resistance of various materials. Suitable for quality testing of electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, medical, aerospace and other products.

Control method: Using the Balanced Temperature and Humidity Control System (BTHC), the induction system transmits the actual data in the Test Chamber to the controller. The controller controls the SSR, multi-stage intelligent output, and balances the output power of the temperature and humidity system to ensure that the temperature and humidity in the Test Chamber are The temperature and humidity are fully stable, and it has an energy-saving function, which reduces the power usage of the instrument to a greater extent and ensures long-term accurate and stable operation of the instrument.

Features

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

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

3. The refrigeration cycle system uses a compressor: an original imported Japanese "Sanyo" brand fully enclosed compressor (optional French Taikang compressor). All components are imported from Japan, France, the United States, Italy and other producing areas. Refrigeration The agent uses American environmentally friendly refrigerant (R23A, R404A).

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

5. It has a fully automatic, high-precision system loop, any machine movement, PLC locking processing, all using PID automatic calculation control, and the temperature in the entire area has high precision and high stability.

6. Specially designed air circulation system and sensing system, the air outlet and return air sensor are detected and controlled to ensure the temperature uniformity in the Test Chamber and avoid any dead spots.

7. Adopt an enlarged observation window and 4 layers of tempered glass to provide a wider field of vision.

8. The instrument has a comprehensive protection system, including power overload protection, leakage protection, control loop overload, short circuit protection, compressor protection, grounding protection, over-temperature protection, alarm audible prompts, etc. When any abnormal situation occurs, the fault will be automatically displayed on the screen immediately. Point out the reason and automatically shut down.

Structure and composition

1. Heating system

• Multi-section heating tubes are used, combined with PID modules, to ensure temperature stability; segmented heating fully saves energy.

• The heating tube is made of high temperature resistant and anti-corrosion alloy tube to extend its service life.

2. Humidification system

• The circular split humidifier avoids the freezing phenomenon that occurs with Water Tank humidifiers during low temperature testing.

• The humidification tube is made of special alloy and can be dry-heated for more than 1 hour when the instrument fails and lacks water. Together with the high-temperature alarm module, it effectively extends the service life of the humidification system. Built-in Water Tank and drawer-type water filling box are convenient and beautiful.

• Equipped with water circulation system, saving 40% water.

• It has a water quality filtration system to avoid clogging of the humidification system and reduce the frequency of cleaning.

3. Refrigeration system
