HR (High Resistance)

This refers to the resistance of an atomiser or cartomiser and is measured in ohms. A High resistance atomiser or cartomiser will have a rating of 3 ohms and above.

This type of atomiser was designed for electronic cigarettes that run on higher voltages, such as 5 or 6v models. These higher voltages will cause a lot of lower resistance atomisers and cartomisers to run to hot and produce a burnt taste. On a 3.7v or lower battery a High Resistance atomiser or cartomiser will produce a low volume of cool vapour and almost no feeling at the back of the throat when inhaled.
