Testo 6351 : Differential pressure transmitters
for critical VAC applications and flow
velocity measurement
The testo 6351 pressure transmitter for differential pressure enables measurements in the 50 Pa to 2,000 hPa measuring range. A particularly outstanding feature of the transmitter is the automatic zero-point adjustment, which ensures high accuracy and long-term stability.
- Automatic zero-point adjustment guarantees high temperature-independent accuracy and long-term stability
- Low measuring range down to 50 Pa ensures very high precision at the lowest pressures
- Measurement of differential pressure, flow velocity and volume flow
- Configurable alarm management with adjustable response delay and alarm acknowledgement
