KAF120 Series IP65/NEMA4 Air Velocity Transmitter with Polycarbonate & ABS Housing and RS-485 Output
The KAF120 Series is a multi-functional transmitter designed specifically for ventilation systems, capable of simultaneously measuring air velocity, air volume, static pressure, and differential pressure. It can be used with various sizes of Pitot tubes to accommodate different duct specifications, with a measurement range from 0-100 Pa to 0-10 kPa.
All models are equipped with a backlit LCD display for convenient on-site real-time data reading. The housing is made of polycarbonate & ABS flame-retardant material (UL94V-0) with IP65/NEMA4 protection, suitable for long-term stable operation in commercial buildings and industrial ventilation environments.
