Bourdon Tube Test Gauges

Test gauges with bourdon tube are suitable for the measurement of positive and negative overpressure between 0-0.6 bar and 0-1,600 bar for gaseous or low-viscosity media that do not corrode brass/bronze or stainless steel.
They are applied when the measuring task requires higher accuracies than those of the bourdon tube pressure gauges, as for example for test equipment or in a laboratory.
