Replacement for Dog Nose

This electronic sensor, developed by Spanish and Swedish researchers is better than a human nose at distinguishing apples from pears.

It has 32 sensors. The mechanism for determining the odor sounds fairly complicated and requires putting a sample inside a "pre-chamber" for analysis. The results can be viewed on a 3-D graph.

Will it replace a dog nose? 

It looks a lot more scientific, certainly, but, for now I'll place my trust in the dog.

Besides, no self-respecting dog is going to want apples and pears stuffed into his pre-chamber.
