Differential Transmitters

Testo 6381 differential pressure transmitter with calculation of flow velocity and optionally with humidity/temperature, accuracy ±0.5% of measuring range final value, automatic zero-point adjustment, selectable measuring range between 10 to 1000hPa, selectable signal outputs, optional display, output of all relevant pressure, flow and humidity paramters.

Testo 6383 differential pressure transmitter in cleanroom-conform panel design, optionally with humidity/temperature, accuracy ±0.3% of measuring range final value, automatic zero-point adjustment, selectable measuring range between 10 to 10hPa, selectable signal outputs, optional display, output of all relevant pressure and humidity parameters.

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.
