GB/T10586-2006 Fast Temperature and Humid Heat Test Chamber With
BTHC and PLC
Product Description:
This test chamber provides a simulated environment of high
temperature, low temperature, high humidity, and low humidity to
detect the materials and strong attenuation of rubber, plastic, and
electronic products before and after the test. The machine can also
simulate the container environment to detect the discoloration and
shrinkage of rubber and plastic under high temperature and high
humidity. Test the heat resistance, cold resistance, dry resistance
and humidity resistance of various materials. It is suitable for
the quality inspection of industrial units in electronics,
electrical appliances, batteries, universities, research
institutes, inspection and quarantine bureaus, paper products,
food, vehicles, auto parts, metals, chemicals, building materials
and other industries.
Way To Control:
The balanced temperature control system (BTHC) controls the SSR in
the P.I.D. mode so that the heating amount of the system is equal
to the amount of heat loss, so it can be used stably for a long
time.
Equipment standard: designed and manufactured according to national
standards GB/T10586-2006 and GB/T10592-1989. *The verification
standard is based on GB/T5170.2-2008, 5170.5-2008
