1000L Temperature and Humidity Environmental Test Chamber Series
with White Color
Brief Introduction:
Temperature and humidity alternating chamber, that uses the
temperature acceleration technique under the design strength limit
(when circulating in the upper and lower extreme temperature, the
product produces alternately expansion and shrinkage) to change the
external environmental ability. Thermal stress is generated in the
product, through accelerated stress to make hidden defects in the
product emerge (potential part material defects, process defects),
In order to avoid changing the product in the process of use, the
test of environmental stress sometimes leads to failure, resulting
in unnecessary losses, it has a significant effect on improving the
good rate of the product and reducing the number of repairs.
Features:
1. Inner box volume:100L, 150L,225L,416L,1000L optional;
2. Different stress screening temperature rates can be set
1.5℃/min;
3. Can carry out rapid temperature change (stress screening),
condensation test, high temperature and high humidity, temperature
and humidity cycle and other tests;
4. Complete real-time test curve analysis shows,no real-time limit;
5. Meet the stress screening of electronic equipment
products,lead-free
process,MIL-STD-2164/MIL-344A-4-16/MIL-2164A-19/NABMAT-9492/GJB-1032-90/GJB/Z34-5.6.6/IPC-9701...etc.

Product Advantages:
1, Energy-saving and electricity-saving water-saving and
intelligent system, 30%~45% less electricity than traditional
machines.
Chamber appearance: high-textured look, The surface is treated with
an arc-shaped white line and baking paint, use of flat reaction
handle, simple operation, safe and reliable.
2, Operating interface:With high sensitivity touch screen mode,
direct touch option, convenient, intuitionistic and easy to
operate. Real-time automatic storage and graphical representation
of humidity PV/SP values, stored curves, group curves, and progress
status.
3, Operating system: Adopt energy saving cold and heat
single-principal balance(Q1-TEST)independent R&D system and
PID+SSR control mode, It can run smoothly for a long time,Precision
of temperature and humidity control,fast rising and lowering
temperature, Uniform and balanced to save valuable time for users.
