SENTRY TECHNICAL SPECIFICATIONS:
NOTE: All pressure ratings for BLACOH products are determined using gauge pressure gauges. This means that when the gauge needle reads zero it is at atmospheric pressure. BLACOH does not use absolute pressure gauges which would read approximately 14.7 psi at atmospheric pressure.
