When managing high-tech layouts, large displays (20 gallons and above), or splitting gas across a multi-tank setup, you need the ultimate level of precision and pressure stability. The UNS Pro Dual Stage CO₂ Regulator is a commercial-grade powerhouse wrapped in a beautiful space grey finish. Featuring a sophisticated dual-stage design, it monitors both your internal tank pressure and your direct working output pressure simultaneously.

Key Features & Benefits

• An expandable bubble counter manifold lets you split your gas supply seamlessly to feed multiple tanks independently from a single regulator.
• Dual high-precision pressure gauges monitor both your raw cylinder pressure and your exact output pressure simultaneously for total system awareness.
• An electronic integrated solenoid allows you to safely automate your daily gas schedule using any standard light timer or smart plug.
• A heavy-duty adjustable control knob gives you smooth authority over your working output pressure all the way up to an impressive 70 PSI.
