The DNA 40 is the first power supply for electronic cigarettes to directly measure and limit the temperature of the heating coil during operations.
By preventing the coil from becoming too hot regardless of fluid, wicking or airflow, a variety of undesirable situations can be prevented.
For example, appropriate temperature settings will prevent the wicking material from charring, which compromises taste and introduces unintended chemicals into the vapor.
Appropriate temperature setting will also reduce the breakdown of flavoring and base liquid components, which could impact taste or safety.
The DNA 40 OLED display will automatically detect whether a temperature sensing (Nickel 200) or standard (Kanthal etc) coil is attached.
Nickel 200 is commercially pure nickel. It is often sold in vapor shops and online as “non-resistance wire”. Historically, Nickel Chromium or Kanthal alloys are used.
If the temperature reaches the maximum value, the wattage applied to the atomizer coil is reduced to prevent overheating.
This to ensure that the coil does not short to itself.
Please note that the temperature reading is the average temperature of the atomizer coil so that the temperature is uniform, without hot or cold spots.
Large vapor volumes can be produced without unnecessarily high temperatures because wattage, not temperature, controls vapor volume.
When the device is firing, the actual average temperature of the coil is displayed on the screen.
When the device is not firing, the maximum temperature setting is displayed on the screen.
