PLS is authorised center for cylinder testing run by Commercial Vehicles Services.They hardly take 2 hrs which includes hydro testing,gas leakage, complience plate and certificate issue.
Staff is very good and technically well trained. I have rated 5/5 as I am very much satisfied by the way they work and also big space for workshop and waiting area for customers..Overall very good experience and highly recommend if you are going for hydro test for your CNG vehicle.
I found them best for hydro test at Noida.
