Refrigerating Cycle High And Low Temperature Test Chamber OEM
brief introduction:
High and low temperature test chamber products with the simulation
of atmospheric environment temperature change law. Mainly for
electrical, electronic products, as well as its components and
other materials in the high temperature, low temperature
comprehensive environment transport, use of adaptability test. Used
in product design, improvement, appraisal and inspection. High and
low temperature test chamber according to the test method and
industry standards can be divided into alternating test, constant
temperature test, two kinds of test methods are based on high and
low temperature test chamber upgrade, alternating test chamber can
refers to disposable will need to do the high temperature, low
temperature, as well as the required temperature of time setting
within the instrument parameters, test chamber will walk according
to the set, The high and low temperature test chamber is to make a
fixed temperature, so that the test effect is closer to the natural
climate, simulate a more severe natural climate, so that the
reliability of the tested sample is higher.
the exclusion of environmental test conditions:
Every time, carrying out reliability test of the environment or the
environmental factors in the category, quantity and tolerance has
strict rules, unless the test required environmental factors
permeate side by side, so that at the end of the trial or trial
judge and analysis of product failure and fault mode, providing the
basis of the exact, so the requirements stipulated in the
environmental testing equipment in addition to providing
environmental conditions, It is not allowed to attach other
environmental stress interference to the test product. Such as the
mesa magnetic leakage, acceleration signal-to-noise ratio and total
RMS ratio of in-band external velocity defined in the verification
regulation of electric shaking table. The test of random signal,
harmonic distortion and other precision indexes are all
verification items designed to ensure the uniqueness of
environmental test conditions.
Safety and reliability of test equipment:
Environmental testing, especially the reliability test, the test
cycle is long, the test object is sometimes worth of military
industrial products is very high, in the process of test, test
personnel often have to operate or test work around at the scene,
so the environment test equipment must be running safety,
convenient operation and reliable in use, long service life, etc,
in order to ensure the normal conduct of test itself. All kinds of
protection, alarm measures and safety interlocking devices of test
equipment should be perfect and reliable to ensure the safety and
reliability of test personnel, test products and test equipment
itself.
