Ralston DV0V-30HG-D DV0V Pump with 30 inHg vacuum digital gauge

Create a vacuum and calibrate pressure devices with included vacuum pump and vacuum gauge.

Light weight, compact pump generates 23 inHg (584mm Hg) vacuum with ease
Large volume fine adjustment piston provides precise control, even at very low vacuums
Modular design makes field maintenance quick and easy
Precisely vent pressure with soft seated bleed valve
Two outlet ports provide connections for both pressure reference and for device under test thus eliminating a tee
Low volume Quick-test hose, gauge adapter and process connection can be attached to pump without thread sealant or a wrench
Rugged, all metal construction reduces pressure changes due to temperature fluctuations
