Overview
Resistance thermometers are essential components in automatic air conditioning systems, used for measuring temperatures in various environments such as rooms, ventilating ducts, outdoor areas, and storage rooms. They ensure fast and reliable ambient temperature measurements due to good thermal exchange with the surrounding air.
