For those times when you need to distinguish between your partner’s farts and the dogs then you will definitely need the smell Inspector.
Now before you go and purchase just for that reason, we may still be a little way off. So unfortunately the dog will still get the blame.
The smell Inspector can smell a number of unique smells that have been programmed into it. Such as coffee, tea, lemon juice, chocolate, meat and fish, and more.
  Chemically it can smell carbon monoxide, ethanol, acetone, and much more.
 So far the smell inspector can be used for food and medicine, safety and security, and manufacturing.
  Detecting early smells or changes in smells can help us detect early signs of trouble or failure in certain areas or products.
