Does this have a calibration certificate? Maybe isn't good enough, i need to know for sure.

No, it doesn't come with one. The unit is too cheap for a calibration certificate to be effective.

Does this come calibrated?

As it’s new I’d say it should be. I have my own test box and when testing the readings are spot on.
