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.
