A top grade electronics/electrical device testing ...

A top grade electronics/electrical device testing laboratory in India. Huge facilities are there. All IT products are tested there before releasing in the market.
For example, if a company makes an action camera that is designed to be IP67 rated, they send a sample to ERTL to confirm/bust it. Varieties of testing instruments are there to simulate environment and the device is put under test.
As a trainee at ERTL, I can confirm that the scientists working there are really knowledgeable and generous too. An ideal place for research.
It's situated right next to the IBM smart city and before techno India. Bus and taxi is the main transport medium. A bus stop is there in front of the ERTL.
Hope this helps. Some images of inside of one laboratory are attached.
