ZRDR R100 Solenoid CO2 Pressure Regulator

Engineered for serious aquarists demanding precision, safety, and seamless control of CO2 injection.

The R100 combines a dual-gauge regulator with a bubble counter and pro-grade solenoid valve. The regulator features high-purity aluminum alloy for resistance to corrosion and humidity. It supports multi-standard cylinder threads and fine-tuned pressure control to ensure ideal CO2 dosing for planted tanks. The solenoid valve stays cool during operation, offering increased safety and longevity.
