Equipment Overview
Samples and restrictions: Parts and materials for electronic appliances, food, automobiles,
rubber and plastic materials, metals, and other products, such as
optical fibers, LCDs, crystals, inductors, PCBs, batteries,
computers, mobile phones, rubber, plastics and other products.
Application: It is used to conduct cold resistance, heat resistance, moisture
resistance, and dry resistance tests on raw materials and devices
such as electronics, electricians, electrical appliances, and
plastics. The purpose is to confirm the reliable performance of
products during storage, transportation, and use in high and low
temperatures and rapidly alternating humid and hot environments.
Test principle: Use heating, humidification, and refrigeration systems to control
and change the ambient temperature and humidity in the box,
simulating the ambient temperature, humidity, and alternating
procedures required by the product.
Structure and features:
This machine adopts a closed-box structure and has the following
features:
1. Energy saving and consumption reduction: Use gas-liquid bypass
mode to adjust the cooling capacity to achieve constant temperature
and humidity.
2. Easy to operate: using Weinview programmable temperature and
humidity controller (7-inch 16-bit true color touch screen),
experimental data recording and processing methods are flexible
3. High reliability: all key components are imported to ensure
service life and reliability; the efficient oil separator ensures
the service life of the compressor.

Function: fixed value test and program test Fixed value test: When the test environment only requires a single
temperature and humidity, select this mode and set the required
temperature, humidity and running time. Program test: When the test environment requires a variety of
temperatures and humidity, select this mode to set the temperature,
humidity and running time of each program, set the program running
sequence, and use 100 program groups |
