Equipment Overview
It is used for cold, heat, humidity and dryness testing of raw materials and devices such as electronics, electricians, electrical appliances, plastics, etc. The purpose is to confirm the products reliability of storage and transportation under high and low temperature alternating heat and humidity.
The sample range can be Electronic & electrical appliances, food, automotive, rubber and plastic materials, parts and materials for metal and other products, such as optical fiber, LCD, crystal, inductor, PCB, battery, computer, mobile phone, rubber, plastic, etc.
The heating, humidification and refrigeration system are used to control and change the ambient temperature and humidity in
the chamber, to simulate the ambient temperature and humidity and alternating procedures required by the product.
This machine adopts a closed chamber structure with the following features:
A. It has an extremely wide temperature and humidity control range to meet the various needs of users.
B. It adopts a unique balanced temperature adjustment and humidity control mode to adjust the ideal temperature and humidity environment. The heating and humidification capability are stable and balanced, and the temperature and humidity control are high-precision and high-stability.
C. Automatic selection of refrigeration circuit: The automatic control device has the ability of automatically starting the running refrigeration circuit according to the set value of temperature, can start the cooling directly under the high temperature state. The refrigeration adopts the air-cooled condensing unit with fully enclosed compressor (imported).
D. The door is equipped with a observation window, which is convenient for observing the test state of the test sample.
