Digital Vacuum Gauge in a Blow Molded Case for Butane, Propane, and BHO Extraction, etc.
This vacuum gauge has been designed with the technician?s field environment in
mind, allowing for self-calibration and a sensor that will not be damaged by
small mists of oil. The Mastercool unit allows for a target vacuum range to be
programmed with a light sensor indicator. Now you have the freedom to continue
with your other work and come back to the system once you see the indicator
light signaling your target vacuum.
