ZRDR 2 Gauge CO₂ Regulator with Solenoid & Bubble Counter
The ZRDR 2 Gauge CO₂ Regulator with Solenoid and Bubble Counter is a professional-grade regulator designed for precision CO₂ injection in planted aquariums. Built with durable brass and stainless steel, it ensures long-lasting performance, safety, and stability.
This regulator features dual pressure gauges to monitor cylinder and output pressure, a precision needle valve for fine flow adjustments, and an integrated bubble counter for easy dosage control. The addition of an electric solenoid valve allows automatic control of CO₂ flow using a timer, ensuring plants receive CO₂ only during the photoperiod—saving gas and preventing fish stress.
