GA-2001-A Programmable Temperature Humidity Chamber
2.Verwendet
This equipment can simulate different environment condition. It’s appropriate for testing material
performance, such as resist heat, resist dry,resist humidity and resist cold. That can define performance of
Material.
GA-2001-A Programmable Temperature Humidity Chamber
Funktion
It simulates the products in the chamber where the climate
condition of different temperature and humidity, such as high-low
operation and storage, temperature cycling, high-low temperature
and high-low humidity, moisture condensation etc. to check its
adaptability and changing performance.
It’s required to conform to international regulation (IEC, ER, GB,
MIL…) to reach the consistency (including test schedule, condition,
method) under the international standard.
Sample application
The chamber applies to:
compatibility test for store, transportation and application of
elektrisch, elektronische Produkte, unit components, parts and other
materials under high or low temperature.
The following samples are prohibited to be tested and stored:
– Inflammable , explosive and other volatile substances;
– Corrosive substance;
– Biont;
– Strong electromagnetic emission source.
