Oxygen sensor bench test video. Good or bad?

You have to replace it now that you destroyed it with a torch.

This link says the O2 sensor range is 0.2 volts to 0.8 volts. Also interesting to note that the link says heated O2 sensors can reach 500C in 8 seconds......closed loop happens pretty quick.
