The Fieldpiece Vacuum Gauge Accessory Head displays pressure in microns in steps of 1 microns. Has pump down indication showing progress from atmospheric pressure.

You'll know your vacuum pump is working and you are drawing a good vacuum as you go from atmospheric to deep vacuum. Set your meter to VDC and see the display drop from over 3.0 to under 2.0 as the pressure goes from atmospheric to under 200 microns. Then switch to a mVDC range to display microns and see pressure in microns of mercury to a ±1 micron resolution.

• Range: 50 to 2000 microns of mercury
• Resolution: 1 micron of mercury
• Pump down indication: when pumping down from atmospheric pressure to 2000 microns, output of head goes from over 3VDC to 2VDC
• Straight-in access to sensor for easy cleaning
• Fitting: 1/4" flared brass fitting (male)
• Accuracy (@~75ºF): ±10%, 0-1000 microns of mercury
• Auto-off can be disabled for data logging
• "T" for inline vacuum testing
