Description
This flex temp device has three voltage levels. Change the voltage level by clicking the button 3 times. Each temperature has a different light color so you never get confused on how hot your device is heating. Low is blue (2.7V), medium is green (3.3V), and high is red (4.0V). We recommend always using the lowest voltage for pre-filled cartridges.
