Alcohol doesn’t only leave through your breath.
Your skin tells a story too.
EthyloKey reads skin ethanol, temperature and humidity to deliver a simple color-coded indication.
01. Power-On
EthyloKey reads the surrounding temperature and humidity before each test.
02. Touch
Smart sensors detect the ethanol released through your skin.
03. Get Result
EthyloKey’s proprietary model combines the signals and gives you a green, orange or red indication.
Your result is a snapshot in time.
One ring. THREE RANGES.
Alcohol levels can rise or fall over the course of an evening. Check again as your night goes on.
