Measuring differential pressure from 10 Pa to 1000 hPa, this transmitter maintains positive pressure in controlled environments and calculates flow velocity from the reading. Additionally, an optional probe adds simultaneous humidity and temperature measurement, and automatic zero-point adjustment preserves accuracy. It includes self-monitoring with an early-warning alarm.
