The Hollis Brass Gauge comes in a rugged chrome-plated brass housing and with scratch-resistant tempered glass. The SPG is oxygen-clean. Available in 360 BAR. It measures 5.8cm (2”) in size and is super easy to read.
It features a bourdon tube, air spool, Viton O-rings and a luminescent faceplate. Shine your torch on the face of the pressure gauge and it will light up, making it easy to read during a night or cave dive. The safety reserve is highlighted in red.
