Product Description
KOMEG Hot Cold Environmental Humidity Test Chamber for Testing LCD Display
Product Application
Temperature and humidity test chamber is also called temperature and humidity
testing machine, constant temperature and humidity experimental chamber, programmable wet heat
alternating test chamber, or constant temperature machine. The Temperature and humidity test chamber
is used to inspect equipments quality and test performance of materials in various environments,
and all kinds of materials properties of heat resistance, cold resistance, dry resistance and
moisture resistance, which is fit for Electronics, electrical appliances, mobile phones, communications,
meters, vehicles, plastic products, metals, food, chemicals, building materials, medical, aerospace and
other products quality inspection.
