Yellow Jacket Hand-Held Vacuum Gauge, Deluxe, 32 to 122 deg F Ambient, 1/4 in Male Flare Connection, LED Display, Battery, Plastic

This easy-to-use gauge shows that air and moisture have been removed from the system.
Simple push of a button changes the display readout between 7 units of measurement.
Each displays from atmosphere to 10 microns (bar graph indication above 25000 microns) of vacuum to let you know that your vacuum pump is clean and performing properly.
If the sensor gets dirty, simply plug a new sensor into the gauge, run through a quick calibration process and be back on the job within minutes.
