AKF10+

Duct/Immersion sensor for measurement of air temperature and other gaseous mediums for HVAC applications (e.g. supply and exhaust ducts). Replaces AKF10 in enclosure USE-S (active/passive) resp. in the newly developed enclosure USE-M (LCD/relay/RS485 Modbus) and pocket Ø=6 mm for faster response. Can be used as an immersion temperature sensor combined with a thermowell pocket.
