Should I use a CVF 3 ventialtion unit in a warm environment and do I need a heater?
The CVF 3 increases the accuracy and maintenance interval by: In the morning dew on the domes is prevented (ice in your region will be no problem) Dirt (dust) deposit on the domes is less with ventilation Zero offset is less because airflow keeps dome and body temperature closer together. The use of the heater in the CVF 3 is not really necessary. (Although also dew is removed quicker) Here the first item is really the most important one. If dew deposit is no problem the CVF 3 can be omitted.
