The complete testing system for gas and water pipes

Unique

Efficient mmeasurement ddue tto
absolute ppressure ccompensation
testo 314 independently
compensates fluctuations in
absolute pressure during volume
flow measurement via absolute
pressure compensation.

Fast

Zeroing pphase ffor cconnected ppipe
To determine ΔP efficiently and

quickly, zeroing to ambient air
pressure takes place while the
measurement is in progress. This
eliminates interruptions and
removal of pipes.

Efficient

Measuring uusing sstandard ttest
pressure ccompensation wwith
feeding uunit

The flow test which is
independent of gas mains, has
the advantage that pressure
fluctuations in pipes can be
compensated. The built-in flow
pressure controller (gas bubble
with gas feeding unit)
compensates for fluctuations. The
finely adjusted value is displayed
in testo 314 along with the
leakage amount.
