ETHAN is a battery operated portable instrument and serves to measure ethylene levels in chambers for storage, maturation, and ripening of fruit and vegetables. The ETHAN instrument uses an electrochemical detector sensitive to ethylene. The measurements are visible on its digital screen.

ETHAN has an internal pump which provides a continuous flow to the detector. By using an external tube which is five (5) meters long, it can take measurements in places that are difficult to access.
