Carbon Dioxide (CO2) supply regulator with dual stage for planted aquariums and calcium reactors in marine aquariums. Includes electromagnetic safety valve, dual manometer, needle valve, and bubble counter.

The PRO-SE series is the new generation of CO2Art's most popular CO2 regulator. It has been completely redesigned, featuring new construction for pressure stabilization. It incorporates much larger internal springs, providing safety and accuracy at the highest level.

The dual-stage design minimizes the rise in outlet pressure as the pressure in the gas cylinder drops and will prevent the end-tank-dump, keeping the aquarium's inhabitants safe and CO2 levels stable.

Features:

• New quality design and completely new construction for exceptional accuracy and safety during use
• Dual manometer with tank volume pressure and operating pressure indications
• Includes needle valve and bubble counter for precision adjustments
• Integrated 12V DC electromagnetic valve
• Adjustable operating pressure +/- 40 PSI (3 BAR)
