An absolute pressure gauge is one that will measure your vacuum system without regard to and independent of local barometric pressure. Many dial (Bourdon) gauges and electronic Transducers reference local barometric pressure as their base measurement. However, since these devices are calibrated at SEA LEVEL conditions, operation of these devices above sea level will cause an erroneous reading. Either the gauge/transducer must be recalibrated for the higher elevation use or an absolute pressure g

Atmospheric Pressure- is variable but is standardized at 760 Torr or 101.325 kPa. Low Vacuum- also called rough vacuum, is a vacuum that can be achieved or measured by basic equipment such as a vacuum cleaner. Medium Vacuum- is a vacuum that is typically achieved by a single pump, but the pressure is too low to measure with a mechanical manometer. It can be measured with a McLeod gauge, thermal gauge, or a capacitance gauge. High Vacuum- is vacuum where the MFP of residual gasses is longer than
