The difference between the enail display screen temperature and the nail surface temperature is important to understand when using a dab enail. The display screen temperature is the temperature reading displayed on the enail's screen and is based on data from the temperature sensor near the nail. However, this temperature may not always be 100% accurate due to factors such as sensor placement or enail calibration. The surface temperature of the nail, on the other hand, is the actual temperature in contact with the concentrate and directly impacts the flavor, potency, and overall dabbing experience. To get the best results, it's recommended to use a probe thermometer to measure the surface temperature and use the display screen temperature as a guide.
