Can it be used to check the radiation level for seafood such as fish or shellfish?

I'm not certain but one of the photos shows fish and radiation symbol. This implies fish can be tested which is useful.

what is the responding time, 5 second, 10second, 1 minutes......?

I didn't time it, but probably 3 seconds. You push the pad on the screen, it flashes a couple times and gives the reading.

What all does this machine test for? Does it chech ph levels, heavy metals, arsenic etc?

This machine test only nitrate concentration in foods. I have test fresh vegetable and for me the results was acceptable.

The greentest website has eco and eco2 , which one is this?

EKO-2 (with radiation levels check).
