2000L Air cooled temperature and humidity test chamber with German
BITZER semi-compact compressor.
Able to accurately simulate a wide range of complicated natural
environments, and is suitable for
reliability test in industrial products. Meet GB5184.108.40.206.6-95
standard requirements of environmental
testing equipment and test methods for the basic parameters of
electric and electronic products under
the condition of humidity, low temperature, high temperature, and
Temperature and humidity test chamber is also called temperature
testing machine, constant temperature and humidity experimental
chamber, programmable wet heat
alternating test chamber, or constant temperature machine. The
Temperature and humidity test chamber
is used to inspect equipments quality and test performance of
materials in various environments,
and all kinds of materials properties of heat resistance, cold
resistance, dry resistance and
moisture resistance, which is fit for Electronics, electrical
appliances, mobile phones, communications,
meters, vehicles, plastic products, metals, food, chemicals,
building materials, medical, aerospace and
other products quality inspection.

Q1 : Can you customize the product?
A: Yes, we can customize any products according to requirements.
Q2 : How to choose the most suitable products?
A: Our professional team will give you the best suggestion,just be
patiently to tell us the information about
the parameters your required.
Q3 : Can you arrange installations and commissioning in our lab?
A: Firstly, for standard chamber we had 3-5 days commissioning
before shipping , you just need link
power in your lab, then can start to operate;
Secondly; we had detailed operation manual with chamber , any
problems you can find and solve in it;
Thirdly, some of customized chambers we should to install and teach
your team to operate.
Packing and Shipment:
(1).Strong standard wood case, inner plastic films wrapped for
temperature and humidity test chamber
(2).Usually we delivery the equipment by air,by sea or by express.
it depends on customer.
