The 532.54 WIKA High Safety Absolute Pressure Gauge is used for pressure measurement of gaseous and liquid media.

Absolute pressure is the pressure that is compared to zero pressure in an empty, airless universe. This reference pressure is the ideal or absolute vacuum. Signed “abs”: Pabs.

The difference between absolute pressure gauges and conventional pressure gauges is best described in the WIKA article Difference between gauge pressure and absolute pressure measurement
