The U-tube pressure gauge, inclined tube pressure gauge and Bourdon tube pressure gauge on the test bench can be used in combination, and the piston pressure gauge can be set to calibrate the pressure gauge to avoid errors caused by instrumentation. The test bench is equipped with two Bourdon tube pressure gauges for Measure the positive and negative pressure, the minimum test pressure is mbar level. Through the relevant experiments designed, students can be familiar with the working principle of basic pressure measurement, and cultivate the corresponding knowledge and skills and the ability of innovation and development.

Features:

Two Bourdon tube pressure gauges are arranged on the test bench, which can measure positive and negative pressures;

The test bench adopts three different principle pressure meters;

The inclined tube pressure gauge on the test bench can amplify small pressure changes;

The test bench is equipped with a piston pressure gauge to calibrate the pressure gauge to avoid additional errors caused by incorrect initial conditions.
