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.
We use PP Film wrapping the test chamber to protect the test
chamber from moisture or being scratched
first, then use strong plywood case for easyload and transport, and
to keep the chambers from potential
crash or impact.
If you face any problems in future during testing process we
promise we will give you a reply within 48
hours and solution provide within 3 working days. We can offer
operation video and English operation
muanual. We can provide video-conference. If customers require
on-site service, the transport and travel
expense shall be borne by customer.
