ZRDR R103 Solenoid CO₂ Regulator — Professional Dual Gauge CO₂ Control for Aquariums

ZRDR R103 Solenoid CO₂ Regulator — Advanced Gas Control for Planted Aquariums

ZRDR R103 Solenoid CO₂ Regulator delivers precise and stable CO₂ flow for aquatic plants, ensuring optimal growth and photosynthesis. Equipped with dual pressure gauges, it provides accurate readings of tank and working pressure for professional‑grade control.

The integrated solenoid valve allows automatic CO₂ shut‑off when connected to a timer, preventing gas waste and maintaining safe levels overnight. Its high‑purity aluminum body and precision needle valve offer long‑lasting durability and fine‑tuned adjustment for aquascaping enthusiasts.

Key Features:

• Dual gauge design for tank and working pressure monitoring.
• Precision needle valve for fine CO₂ flow adjustment.
• Automatic solenoid valve for day/night control via timer.
• High‑purity aluminum construction for durability and reliability.
• Compatible with standard CO₂ cylinders and diffusers.

Usage Instructions:

• Connect the regulator securely to a CO₂ cylinder.
• Attach the solenoid valve to a timer for automatic operation.
• Adjust the needle valve to achieve desired CO₂ flow rate.
• Monitor pressure gauges regularly for stable performance.
