250L Air cooled Temprature And Humidity Testing Chamber With LCD touch screen controller
Able to accurately simulate a wide range of complicated natural environments, and is suitable for
reliability test in industrial products. Meet GB5220.127.116.11.6-95 standard requirements of environmental
testing equipment and test methods for the basic parameters of electric and electronic products under
the condition of humidity, low temperature, high temperature, and constant heat.
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.
