Complied Standards & Clauses
According to IEC60068-2-1:2007, IEC60068-2-2:2007, IEC60068-2-78:2001, IEC60068-2-30:2005.
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.
