In reality, there is NO need to know. The end-user is a connoisseur, so they know what they want. For the SSV and any whip vape, the temperature is so greatly affected by the speed of the inhale so to show a temperature is in reality not true.
The SSV is designed for someone who likes big hits, to someone who likes really smooth light hits.
One thing you do not want to do is let your herb turn black or dark brown from the first hit. This means turn it down a little or inhale faster
