The Hollis Low Profile Brass Mini Gauge is a beautifully compact Submersible Pressure Gauge (SPG) by Hollis,. It has a highly contrasted black background with white markings and a luminescent needle, so you can easily decipher your remaining tank pressure.
The low profile and low weight of the SPG allow for a streamlined rigging. It is the perfect SPG for stage and deco bottles or as a backup instrument. It is a standard model with Air Spool and Viton O-rings featuring a super hard PVD coated brass housing with Bourdon tube and a scratch-resistant plastic lens. Furthermore, it comes oxygen clean out of the box.
