Digital Portable Environmental Chamber Horizontal Low Temperature
Test Chamber
Environmental Test Chamber.pdf
Equipment Overview:
The equipment is mainly composed of box, refrigeration system, air
circulation system and control system. The box is horizontal, the
shell is made of matte stainless steel, the inner liner is made of
high quality mirror stainless steel plate, the middle of the box
cover is equipped with a large observation window, and equipped
with observation lights, so that the user can clearly see the test
condition of the specimen. The overall appearance is beautiful and
generous. The insulation layer is rigid polyurethane foam plus a
small amount of ultra-fine glass wool, with high strength, good
insulation and other characteristics. The main temperature
controller of the equipment adopts intelligent digital display
temperature and humidity controller, humanized design of the
operation method, easy to learn and use, and the operation of
different functional grades of instruments are compatible with each
other. Refrigeration system adopts fully enclosed imported
compressor set, mechanical single-stage refrigeration or compound
low-temperature circuit system, fully automatic control and safety
protection coordination system.
Main Functions:
The equipment is mainly for electrical and electronic products, as
well as their original components, and other materials in the high
temperature, low temperature environment storage, transportation,
use of the adaptability test. The test equipment is mainly used for
products in accordance with national standards or user
requirements, in low temperature, high temperature, conditions, the
product's physical and other related characteristics of
environmental simulation testing, testing, through testing, to
determine the performance of the product, whether it can still meet
the predetermined requirements, in order to product design,
improvement, identification and factory inspection with.

Annotation 1. Above data were measured at temperature (QT) 25oC and no-load
condition. 2. Can be customized non-standard-type high-low-temperature testing
mechine according to uses requirements |
Main Features:
1.Refrigerator adopts French original "Taikang" totally enclosed
compressor.
2. Refrigeration system adopts unit or binary type low temperature
circuit system design.
3. the use of multi-wing fan strong air circulation, to avoid any
dead space, can make the test area temperature distribution evenly.
4.wind circulation out of the wind back to the design, wind
pressure, wind speed are in line with the test standards, and can
make the door open instant temperature back to stable time fast.
5. the box adopts horizontal, generous appearance, and large volume
of the inner box.
6. The temperature control adopts imported touch button instrument,
simple operation setting.
7. After the data and test conditions are input, the controller has
a lock function to avoid changing the temperature value by human
touch.
8. With P.I.D automatic calculation function, the temperature
change conditions can be corrected immediately, so that the
temperature control is more accurate and stable.
