CHINA NBC-225L-40 Programmable Humidity chamber -40 ℃

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 and ensures long-term stable operation of the instrument.

Features

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

• 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 the instrument directly through the computer.

• 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 production areas. The refrigerant is American environmentally friendly refrigerants (R23A, R404A).

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

• 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.

• The specially designed air circulation system and sensing system, with sensors detecting and controlling the air outlet and return air outlet, ensure the temperature uniformity in the Test Chamber and avoid any dead spots.

• Adopting an enlarged observation window and 4 layers of tempered glass, the field of view is wider.

• The instrument has a 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 point and cause will be automatically displayed on the screen. And automatically shut down.

• The heating system adopts multi-section heating tubes and cooperates with the PID module to ensure temperature stability; segmented heating fully saves energy. The heating tube is made of high temperature resistant and corrosion resistant alloy tube to extend its service life.

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

• The pipelines used in the refrigeration system are all made of imported copper material. Its advantages are good flexibility, not easy to break, and good shock-absorbing effect on the long-term vibration characteristics of the refrigeration system.

• The screen is an imported 7-inch color touch screen. Chinese and English can be switched at will. The backlight of the screen can be adjusted. The screen display protection function can be timed or manually turned off.

• It has power-off program memory and can automatically start and resume program execution after power is restored.
