The Bullseye precision gauge is a rugged portable vacuum meter designed to withstand field use without compromising accuracy. Although calibrated in air at the factory, any dry noncorrosive gas is compatible. A correction factor based on the thermal conductivity of your gas is all that is required to convert readings. Or, recalibrate in the field to your specific gas composition.
Analytics provide a quick visual graphic of the problem (pump, leak, out-gas or stable), eliminating having to guess system status based on current numeric readings alone. Trends are graphically displayed over time, indicating the progression of pump down throughout the evacuation and giving you an early warning that a leak is present.
